Can a bloody nose give a false positive covid test? I got a positive test?

[Anonymous]

I am bleeding in one nostril only and I took a swab with both nostrils and it came back with a positive

I have taken 4 more tests with just one nostril the one that is not bleeding and they are all negative

My mother has a negative test and she tested both nostrils and i live with her

Am I positive or is it the blood?

I tend to avoid at home nasal swab tests in general. Simply because it seems like it's really easy to cause a nose bleed using them and a nose bleed in general. Also it's like repeatedly blowing your nose. The more you blow your nose or swab your nose, the more likely you are going to get a bloody nose at some point.

The blood is immaterial.

You probably had a bit of covid particles in there somewhere, or it was a flase positive.

Give it a week and then test again.

I've tested 4 more times but just with the one nostril that is not bleeding. Wouldn't covid still show in the one nostril?

im a covid tester and blood, as with saliva, ruins the sample... incidentally lfd home tests can be fooled with something as simple os coka cola or a fruit shoot.

[wankiam]

lfd test or pcr... lfds are quite innacurate but almost always a ruined pcr swab will return an inconclusive result. false positives are very rare with a pcr test

These are the at home ones

[wankiam]

so when you get a positive home test its advised that you go for a proper pcr test which will give you an accurate result. i suggest you do that but given the other three were negative i think you should be fine

[Asker]

Or are they negative because I only tested one nostril and nothing else?

[wankiam]

just go for a pcr... incidentally i work at a covid test centre so unlike others here, my opinion is better based in fact

[Asker]

I'm going for the PCR in the morning

If the lateral flow test is positive due to the blood and the PCR test is negative then is it safe to say its the blood?

I tested again and there is less blood on the swab and the positive line on the test is more faint. The blood was stronger before when the line was really strong

I read that juice etc can give a positive result due to the acid. Maybe my blood Is acidic?

That is possible

[wankiam]

so what did the pcr test say?

Go and get a proper test not the silly ones you do at home as you can easily contaminated them

[Iron_Man]

Just redo the test

I doubt it
