Anyone here got the scoop on antibody tests? I took one yesterday from LabCorp and it came back positive with a count in the 60s U/mL. Reading around this seems like the baseline for prior infection (my exposure was ~6 months ago) as some people get scores in the 1000s+, but antibodies also arent the full picture as T-cells are an important factor as well. Hong Kong uses 50 as a threshold for antibody immunity. Wondering if anyone here has definitive info on this subject because i havent seen much yet.
Also i took my 1st antibody test at CVS last month and it came back negative so i wouldnt even waste your time with them if youre interested. They took a tiny sample from pricking my finger and ran it through a one-off handheld machine. LabCorp did a full bloodwork sample from the artery, had my result within 48 hours, and was about the same price (and had options for insurance but its <$50 total).
Why are taking one in the first place? My understanding is that they are just another version of the PCR test, which is incapable of diagnosing infection. There is no test for COVID-19, since (1) the PCR and its 200 to 300 versions of it cannot diagnose an infection. (2) There has never been any virus ever that has been isolated and purified. You are taking a ride to nowhere.
Business Insider reports: A new study evaluated the accuracy of more than 60 coronavirus antibody tests. 13 were a cut above the rest.
Blood draws are from a vein, btw. The only blood tests from an artery would be an arterial blood gas — painful procedure, takes some skill.
Business insider is buzzfeed for finance bros so ill take ot w a grain of salt. Good call in veins though i was high af when i wrote that last night
That should be our vaccine "passport"
