Antibody test AFTER a vaccine

[TheGoodEnoughWife]

Hi, has anyone tried a at home antibody test after they have had the vaccine?

I was hoping for one where you drop the blood in and it tells you within minutes (similar to a pg test) although most I am finding online you send away.

I know I would need to leave it maybe four weeks after the jab?

I would just be interested to know if I have any coverage after first jab last Saturday!

I'm about ten weeks post dose one (and 24 hours post dose two, woohoo!). I'm doing monthly antibody tests as part of a research project.

The most recent result I have reads:

N-antibodies: Not detected
S-antibodies: Detected

Apparently if you've had an infection, you're likely to show both N and S antibodies, but the vaccine induces just S-antibodies.

I don't know what N and S stand for in this context.

I had Pfizer, but the info leaflet from the trial organisers doesn't specify that there's any difference.

I'm doing it too. My latest results are:

N-antibodies: Detected
S-antibodies: Detected

• same as last month, so at least it's consistent. Apparently "This indicates that it’s likely you’ve previously been infected with SARS-CoV-2."

However, husband had no detectable S-antibodies - and I've barely been out of the house in the last year, let alone been ill!

(First Pfizer vaccination in February. )
