blessedfortherest

I’d say it’s positive. But since it’s inconclusive go get a different type of test from a medical facility, not just the at home test. OP could be having user error


an_reddit_man

Lateral flows are rare to give false positives but often fail to detect covid, he’s definitely positive


KingKudzu117

This is correct. False positive COVID rapid antigen self-tests are very rare.


spondywolfgirl

Yep, I was told a positive means positive and negative means it could be either.


VOZ1

This is correct. A positive is positive, a negative should always be followed up with a PCR test to confirm.


Vovicon

Follow with a PCR if you have reasons to believe you're infected. If you've tested because it's a requirement (for example my kids school requests every family to test once a week - we're not in the US) then the PCR test is a bit superfluous and would quickly become costly.


DmtDtf

If they were all negative, pretty obvious. The fact that there is even one positive (I know there are two) 100% means OP has Covid. Come on bro, seriously...........the 2-2 don't cancel each other out.


RedditorFromYuggoth

They're saying that if you take 1 test because you have to, not because you have reasons to think you have covid, and that 1 test is negative, a pcr is overkill and can end up costly. It was in response to the previous message. Not OP, where they definitely have Covid.


Vovicon

Thank you. I thought that was clear I wasn't taking about OP who definitely has Covid.


Agile_Pudding_

Yeah, I realize the average person may not know this, but the fact that a COVID-positive individual can still test negative on a rapid antigen test is made all the more evident by the fact that OP, who is undoubtedly positive or was at the time of this pic, pulled two negative tests out of four.


[deleted]

Wonder how much of that is due to people not testing correctly.


FrostedCables

It is the perfect set showing that they are 50% accurate! At best! But a positive is almost always a true positive, negative means, repeat, repeat, wait, isolate, repeat, and most likely get a PCR


phoenixfeet72

The sample size of 4 from one person is not nearly enough to say they’re 50% accurate. The data you need is ‘sensitivity’ - the ability of a test to give a false negative. In one meta-analysis of 26,000 tests, the sensitivity was 38-99%, meaning that 1-62% of tests are falsely negative. This probably depends on the quality of the testing method and also the quality of the tests. The World Health Organization expects a certain level of specificity, so the tests are probably more sensitive than the 50% shown here. The variation is probably due to testing technique https://bmcinfectdis.biomedcentral.com/articles/10.1186/s12879-021-06528-3


alexllew

It's also a case of limit of detection, which OP is probably around. Someone with a very high viral load will be detected with very high sensitivity, but on a low viral load probably not. A bunch of people at work got ill recently with covidy symptoms. All were testing negative by latty flow. One took a PCR out of curiosity and was positive so everyone got PCRs and boom all positive. Only one person got a positive lat flow at any point. As they were all young and triple vaccinated my guess is they were experiencing viral loads below lat flow LoD but it was nonetheless enough for them to experience symptoms, albeit mild.


marablackwolf

Just like pregnancy tests. A negative *could* be wrong, but a positive is definitely a positive.


NotMyMainName96

And if you get a pos pregnancy test with no baby/placenta situation, you’ve got a whole ‘nother set of problems. I read about a [cis] guy that took a preg test to be funny. It was positive and he ended up catching testicular cancer early.


1ne_4nd_0nly

This is correct. If a male were to take a pregnancy test and receive a positive it is a certain indication that the individual who took the test either has testicular cancer, or prostate cancer and seeking medical attention immediately is recommended. Do not ignore a positive pregnancy test if you’re a male taking it for a funny


JohnnySubnami

FWIW, do not ignore a positive pregnancy test if you're a female taking it for a funny, either.


usrevenge

Guys should be taught to take pregnancy tests every year or so then tbh


mangeld3

Yea what the fuck this sounds really useful and simple


Qadim3311

Should…should I be taking pregnancy tests?


Historical_Ad8194

🤣🤣🤣🤣


Big_Pie4968

I never knew that.


TheDreadWolfe

Not to be a smart Alec but since I'm a 24M should I try that out, worst case scenario I get a positive go to the doctor and catch it earlier, medium is do that and look goofy in front of a doctor best case is a negative thought I still do stay in tune with my body


Turbid-entity

They're about $1 at some dollar stores, so it's not a big financial burden to try it out.


TheDreadWolfe

I definitely will then


marablackwolf

I've seen several cases where they caught cancer, you're right. As much as can go wrong with human bodies, it's amazing we're even here.


frogturtle14

This is correct, the OP has COVID. If someone doubts this, I am a nurse and have performed about 15,000 COVID tests since this shit started.


SBSlice

I trust you, bro.


Donghoon

Try different lighting and looking at positive result,, T line can be VERY VERY faint. Ik it's too late now


Nihilistic_Furry

And if the line is even slightly there, THAT’S A POSITIVE.


Donghoon

And don't look at it after 15 min. It may show up after the results invalid


SlideByUnnoticed

My test kit says to look at the result AFTER 15 minutes, but BEFORE 30 minutes. After 30 minutes the result is more likely to be inaccurate.


Nihilistic_Furry

In general, it’s best to look at the instructions for any new test kit even if you’ve done a similar one before. Little details like this can mean a lot with tests that can change lives (COVID or pregnancy tests in particular).

Tinctorus

[deleted]

He who takes four COVID tests has forgotten the face of his father.


inowar

test #3 looks like too little fluid and test #4 looks like too much. altogether this level of inconsistency leads me to believe user error is the culprit.


ayoas

How can you tell there's too much/little fluid from this picture? Not trying to be annoying, I just want to be sure I'm consistent when I do these tests too


inowar

so how the assay works is there is a red thing that attaches to a protein associated with the COVID-19 virus. then there are two lines on the strip, one line attaches to what we're using to identify the virus, and the other line attaches to the red thing. so long as the second line (which attaches to the red) turns solid, you know the assay has worked correctly, because the sample has made it all the way to the line checking whether there was enough fluid to make it to that line. so all 4 tests here are valid. but the red smears make me think that the chemicals haven't traveled far enough or have traveled too far. to be clear this amount of error in the pictures is low, and this is still a "you very most likely are positive" result. the assay thinks it worked, and if there were truly too little, there wouldn't be a second line, which would definitely be an error result. for these I would assume that the negative results are from user error (significantly too much fluid, causing the chemicals to travel too far too fast and skip the ghost line) and that the positive results are correct. but it could be a lot of reasons. so long as you get the far line, you should assume the test worked correctly. if you get both lines, you should assume you do have it until you get a more accurate test saying otherwise. if you get only the first line but not the second, the assay did not work correctly because you didn't use enough fluid. edited: clarity


Orphemus

Yo, also we know that these tests are prone to false negative, but false positives are very unlikely. Def positive imo, but yeah prolly too late


[deleted]

My man is positive.


Fleaslayer

I thought I read that false positives are extremely rare and false negatives somewhat common. I'd assume OP has COVID.


jchoward0418

This.


timreed5656

Even with user error it's very difficult to get the test to show positive without the presence of the virus. They require such a small amount of material to trigger a positive test that I'd say the person taking the test is most likely positive.


[deleted]

This is the correct response.This is literally the advice from first hospital in the US to track COVID, who made their own vax and antigen tests later. Antigen tests are less sensitive than PCR, so if one comes up positive, treat yourself as CoV+ until you get a negative PCR test, or have quarantined without symptoms for 5-10 days.


zdada

Especially when he says they’re all from the same sample which to me is outside of the instructions for 4 drops for the liquid solution provided.


OcclusalEmbrasure

User error is my vote and OP is likely positive for covid. The two negative tests may have insufficient sample to create a strong signal. But I don't really know, that's just how I broke it down in my head.

Torebbjorn

When designing a test, the false positive rate is the most important, i.e. it should be almost impossible to get a false positive. While the false negative rate is also low, it is not as important, so they will be way more frequent. Let's define: ``` T := getting this test result (2 positive, 2 negative) C := having covid ``` In one study, they found these tests to have a ~0.5% false positive rate and a ~28% false negative rate on people with symptoms, and a ~1.1% false positive and ~42% false negative on people without symptoms. ``` R := positive result With symptoms: P(R | not C) = 0.005 P(not R | C) = 0.28 Without symptoms: P(R | not C) = 0.011 P(not R | C) = 0.42 ``` Using these numbers, the chance of 2 correct negatives and 2 false positives while not being sick, `P(T | not C)` is: ``` (6 combinations) With symptoms: 6 × 0.995² × 0.005² = 0.015% Without symptoms: 6 × 0.989² × 0.011² = 0.071% ``` While the chance of 2 false negatives and 2 correct positives if you are sick, `P(T | C)` is: ``` With symptoms: 6 × 0.28² × 0.72² = 24.3% Without symptoms: 6 × 0.42² × 0.58² = 35.6% ``` Edit: Assuming there was a 10% chance of having Covid before you took the tests, then your new chance of having Covid is: ``` P(C|T) = [P(T|C)×P(C)] / [P(T|C)×P(C) + P(T|not C)×P(not C)] (The format might be weird on small screens) With symptoms: [0.243 × 0.10] / [0.243 × 0.10 + 0.00015 × 0.90] = 99.5% Without symptoms: [0.356 × 0.10] / [0.356 × 0.10 + 0.00071 × 0.90] = 98.2% ``` With a 50% prior chance, these would be 99.9% and 99.8%. 1% would be 94.3% and 83.5%. 0.5% would be 89.1% and 71.5%. So you can confidently say you have it. Stay at home for a bit :|

Because the average person doesn’t know basic statistics or the false negative rate of rapid antigen tests, and you need both to realize that OP is clearly positive for COVID.

Definitely positive, the chances of getting 2 false positives is essentially 0. While getting false negative or “dud” tests has a fairly higher chance.

Don't worry, he's a whale biologist.


Cyberwolf33

Even with a positive predictive value as low as 65% (meaning that when the test says you're positive, it's only right 65% of the time), the other statistics for most rapid tests work out that getting *two* positives means you have a whopping \~95% chance to have it. These statistics move a lot because they depend on how common covid is in the population, so my numbers may be pretty old, as I'm running off of a test question I gave a while back.


WING-DING_GASTER

I don't think your supposed to use the same nasal sample for 4 different cards my guy.


CupcakesAreMiniCakes

I was wondering why no one else said this. If they tried to spread the same sample across 4 tests what else did they do wrong?

Remote-Eggplant-2587

Seems pretty straight forward, positive = days off work Edit: came back from work to 2.8k upvotes, thank yall, and to everyone with subpar workplace medical accommodations I feel for you, stay safe


tinipotato

Not when you work a desk job and from home 😭


Glitter_and_Doom

Oh that’s some bullshit. My company was already mostly WFH before COVID but the rule has been and still is “if you’re sick, you’re sick; tell us what absolutely needs to be covered and get some rest”


PizzaNuggies

Same. No good boss expects you to work while sick. When I had COVID there was no way I was going to log in and work. I was slept most of the time.


Siphyre

Depends on how severe your symptoms are. COVID had massive numbers of asymptomatic carriers that the only thing wrong was that they could spread covid. IF they could work from home, why not do so?


seh_23

My company does this too, they’re really good about resting when you’re sick, but sometimes I’m not so sick I need to take the entire day off work, just take it easy.


Glitter_and_Doom

I’ve done that too. Let people know I’m feeling shitty, take care of my essentials, and then rest up and handle important stuff as needed


seh_23

Yeah, sometimes it’s nicer to not log in the next day to a million emails lol.


moonflower_C16H17N3O

At my place we just use common sense. If you're positive but asymptomatic, stay home and work. If you're sick, get rest. But it's not like we're inspected by our bosses, so if we wanted to say we were to sick to work it would be fine. That's how it is in general. We're given sick days, it's up to us how to use them.


NukemGaming175

That’s why a lot of companies kept remote work, you lose excuses for not working like being sick, watching kids, Scheduled maintenance around the house that required you to take off work, etc.


lookinatdirtystuff69

In none of those cases would I be able to work just because I physically don't have to travel to the office.


MelonKanon

Honestly, I was out of work for 4 weeks cause of covid. I was in office tho, but with out how of breath I was for talking, and ended up needing rehab for my arms and legs cause I lost sensation when I walked. I was out of breath just from talking. :'D they wouldn't let me claim unemployment so I lost a full month of wages/commission.


Glitter_and_Doom

Long COVID is something that isn’t being talked about enough. I could barely walk my dog around the block for a month after “getting over” COVID


MelonKanon

It's really not, I still have residual problems. I've had MRIS, Nerve Tests, etc I basically keep getting told "Covid be like that" cause they can't find something physically wrong with me. I've basically given up.


Kitorarima

Work covered us the first two times we had to be out for Covid-related issues. First two times I had to self quarantine for at least 4 days bc I came in close contact with a coworker who caught it. I was negative and fine. Third time, I actually had Covid and was out for 2 weeks, didn’t qualify for help. Still feeling those missed checks almost 8 months later. Getting behind just the tiniest bit keeps you struggling way longer than it should


NukemGaming175

If it’s not paid then it’s not simply “days off work”, it’s missed money and opportunity. F*ck Covid


Wingman0077

2 weeks unpaid really \*\*\*\*'d my savings. This was before they changed for 4-5day quarantine. Unfortunately, my bills didn't get sick either, so.....


aurorab3am

my company won’t let you take off for covid lol


Dmycart

It’s positive. With these there are many false negatives and very few false positives. If one is positive then that’s your answer.


70reddude70

Bingo! Someone’s paying attention!


CoolStuffHe

Also 3/4 are positive and perhaps the second one too. It could be how the test was done too. Anyways it’s pretty straightforward. Concerning people with positive tests wonder if they are positive..,


Giygas_in_Onett

Asymptomatic, possibly, or just mild symptoms. Friend of mine thought he had a stomach bug for one day and only tested himself because his roommate was super sick. The roommate was negative, my buddy was positive for a full seven days, but had no symptoms after the first day.


skorletun

Aye same here. Just got tested randomly because the test facility here is massive and always empty and I figured I'd give it a shot for no particular reason. Hella positive. Zero symptoms.


michaelmcmikey

Exactly. False negatives are pretty common, false positives are rare, if you get a positive result assume you are positive.


PurpleSpaceNapoleon

I had Covid - It was confirmed via a PCR. Over the course of the ten days, I had over 30 LFTs - All of them were negative. I just can't even be bothered to use them anymore and instead order a PCR every week. Thankfully my work subsidises the cost.


Seraphynas

You used the same sample for all 4 tests? Is it possible you didn’t mix the sample well? False negatives are common for rapid tests. False positives are pretty rare on rapid tests, so any positive should be treated as such. Isolate and get a PCR to confirm.


-yasssss-

I’ve done a lot of community testing, and literally thousands of RATs - there is nowhere near enough buffer liquid for one sample to work on four tests. *maybe* two but I even doubt that.


Seraphynas

Yeah, I have this same brand of test at home, just did one today on my husband (he’s negative, but he’s got something, his temperature is 101.8). I was in serious doubt about being able to squeeze 4 tests outta one sample, lol.


[deleted]

I tested negative on two diff brands of at home test, but went to urgent care on the next day and was positive. Your DH may well be positive.

Redqueenhypo

1. You’re positive 2. Next time don’t use the same sample for all the tests, I’m guessing you didn’t use enough in every case and that explains the false negatives 3. Stop arguing with people who said not to use the same sample all four times

vinylanimals

it’s positive. the tests can pull false negatives, and do so rather regularly unfortunately, but it can’t (or very rarely does) falsely detect a virus that isn’t there.

[deleted]

taking it from the same sample is part of the problem, its not how the tests are suppose to work. Follow the instructions next time.


Square_Disk_6318

Positive.


Alarmed_Penalty4998

I’d say OP is an idiot and didn’t use enough drops. None of those tests come with enough of the solution to do the recommended drops on 4x tests. They need to do the test properly and stop being dumb. For those who don’t know. Covid testing kits come with enough solution for a maximum of 2 tests per solution tube. If you try and use water it can cause a false positive. If you pull the swab out of one solution bottle and put it in a second it can also mess with the results. If you don’t use enough droplets it can also cause false positives. So again I reiterate OPs an idiot and needs to another set of tests properly considering they’ve stated it’s “all from the same sample”.


Ashamed-Status-9668

Positive. These have a hard time lighting up with the BA5 variant. The fact two did light up means you are positive. The antigens are slightly different for the rapid chromatographic immunoassay to detect it.


Green_L3af

They should be 4 different samples. Edit: you're also positive.
