Based on that, I would be considered high and eligible for plasma donation



At what point was your result 109? How long after your recovered? Did you have any severe (or mildly severe) symptoms? [my symptoms last year were diarrhea for about two days, low grade fever for one day, loss of appetite and overall weakness (the latter two symptoms bringing about a nice ~20lbs drop in body weight, which was unfortunately since regained). I didn't lose taste or smell (though I disliked seltzer for a couple of weeks), nor did I have any difficulty breathing or coughing.]

Isn't the NYC HHS test the Roche Elecsys Anti-SARS-CoV-2 (not Abbott)? The chart you screenshotted shows COI of >109 to be considered high titer for the Roche test I'm referring to.

Entire family should quarantine for 10 days from onset of symptoms, and until they are without fever for 24 hours.

If possible patient should isolate, especially if there are seniors or other at-risk people on the household, and certainly if they didnít have COVID in the past 6-8 months. Family doctor should be consulted for details on what and how long.

And to be clear, if the family does not separate from each other, the timeline for the exposed family members wouldn't start until the end of the covid patient's 10 days.

If that's the case, it may be worth testing individual family members in case they are presymptomatic, so you can start counting earlier. As always, ask your doctor.
Workflowy. You won't know what you're missing until you try it.

6 negative Covid tests, 6 negative antibody tests (despite me having gotten the vaccine and my wife having tested positive!!)
Where/what type?
https://www.fda.gov/media/137603/download
Vaccinated (2nd dose?) when? Tested positive when?
Tested positive 12/29
Second shot 1/17
Anyone with any theories in this? Problem with the antibody testing? Problem with my shot? False positive for my wife on covid test?

False positive COVID test is certainly a possibility.
Not all antibody tests detect the vaccine's antibodies.
Try the Roche semi quant at Labcorp/Walgreens (You'll need an Rx from a Dr for Labcorp test 164090)
Save your time, I don't answer PM. Post it in the forum and a dedicated DDF'er will get back to you as soon as possible.

Faulty antibody test is the only option that answers all the questions, so probably the most likely, IMHO.

You'd have to assume both of those are true, which may be, but a false positive COVID test is much less likely than a false negative antibodies test.

My wife also had a negative antibody test on January 15th (though at the time, we chalked that up to being too early)

Free from the kupah with a doctor's referral (I'm eligible because I lived with someone who tested "postive"). I don't think it's a quant test though

Just walk into any labcorp with an Rx, they're in most walgreens these days. Can also make an appointment on labcorp.com.

Unfortunately not at any of the walgreens within 10 minutes of me. Too much effort
