Baffled

Done antibody test I'm positive for lgG negative for lgM

I only had my second jab in October why would I not have antibodys from a vaccine ? Or have I got them the wrong way round ?

TA

Isn't there an instruction leaflet that tells you how to read the results?

@SerfNTerf yes I'm confused as to why I have no antibodys from the vaccine but am positive from previous infection

I have a similar antibody test here and it doesn't say anything about testing for vaccine antibodies. What does it actually say each line refers to?

@SerfNTerf

Ok we have the exact same tests! Mine has a bigger leaflet that explains how to interpret the results. I'll take a photo of the relevant bit after I've done the dishes!

@SerfNTerf thank you 😊

IgM is short lived (weeks) where as IgG persist for months.

@vickyc90 thanks I'm really struggling to understand if I have antibodys from A previous infection or the vaccine

They are both for antibodies after infection. Not vaccination

...it isn't a test for vaccine antibodies

It's doesn't tell you that unfortunately, it only tell you a yes or no to whether you have antibodies. A IgM would imply you have been vaccinated or been exposed recently. IgG on its own indicate it wasn't within the last few weeks.

Infected people generally have a higher IgM & IgG post infection with a subsequent vaccination than someone post vaccination who has never been exposed.

But that isn't a quantitative test, to be fair the only times I've seen it quanted is in research.

This might help

@vickyc90 ok thanks I bought this test as they told me that the test tells me it I've ever had covid 19 😞

Is it an Anti-N test? I haven't seen an at home anti-N test only the Roche one where you send off a finger prick. Do you have a link in tempter now if its anti-N. None of the vaccine produce an Anti-N so if you are Anti-N IgG positive that would indicate a past infection some weeks ago as you have no IgM.

The fact it's IgG vs IgM only tell you a time.

@vickyc90 I got it www.zedmed.co.uk/store/Panodyne-Covid-19-Antibody-Rapid-Test-Kit.html

@vickyc90 can u let me no if it is 🤦‍♀️ I have tried to look but no clue what I'm doing

It doesn't specifically say either way which is naughty but reading it from a science perspective I very much doubt it's Anti-N as they would shout about it if they had managed it. The Roche one is UKAS accredited so is more reliable if you want to know for certain.
