You might have better insurance than many here.
Has anyone here been denied coverage?
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.

Has anyone here been denied coverage?

As in: provider doing the test and submitting it only to get it denied and billed directly to patient?

Or do you mean: provider won't administer test because it isn't pre-approved, and you're on record with us as having had the test recently?
I've been waiting over 5 years with bated breath for someone to say that!

Tested now a full year later.

Bh.

I wanted to see where I'm holding ahead of vaccinating.

Brother and sister both recently tested with very high levels after having it last March.

Did you have any exposure in the interim?

Nobody close to me confirmed. No idea though.

had covid in mid dec 2020, just took a anti body test on fri at chemed. the results seem to show i had it but dont show any levels....is that weird? how can i see the level of antibodies?

COVID-19 Antibody, IgG
NAME   VALUE   REFERENCE RANGE   LAB
F   SARS-CoV-2 Antibody, IgG   Positive   Negative    RN
- Results suggest recent or prior infection with SARS-CoV-2. Correlation
- with epidemiologic risk factors and other clinical and laboratory
- findings is recommended. Serologic results should not be used as the
- sole basis to diagnose or exclude recent SARS-CoV-2 infection. False
- positive results infrequently occur due to prior infection with other
- human Coronaviruses.
- This assay was performed using the DiaSorin Liaison(R)
- SARS-CoV-2 S1/S2 IgG assay.

You took a qual test. You need a quant test for that.

The best one is the Roche Labcorp test 164090. A Dr can write an Rx for that test code.
Cost is about $50, should be covered by insurance.

The Roche test administered by NYC HHC is qualitative as well, does that mean that the number on this test is meaningless (compared to a quantitative test) for determining antibody levels?

based on what we know:
if you pass the threshold for qual test, should be fair to assume that you're (still) safe today. how long that will last? nobody knows, but quant tests can give some ideas

Someone on DDF just reported today of known reinfections with recent confirmed antibody, so it isnít 100%:

My chavrusa was informed by the doctor at Friendly Urgent care that they have seen ~25 cases of people with prior antibodies getting reinfected in the last week. His cousin with *very* recent antibodies (tested within the last month) tested positive as well.

Why do you say it's qualitative?

Don't know if this is current, but it doesn't mention either qualitative or quantitative.

https://www.fda.gov/media/137603/download

If they give you a number, that's by definition quantitative, no?

Sorry, my bad, I read it here:

Immunoassay to qualitatively detect antibodies against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)
Elecsysģ Anti-SARS-CoV-2 is an immunoassay intended for the qualitative detection of antibodies to SARS-CoV-2 in human serum and plasma. The assay uses a recombinant protein representing the nucleocapsid (N) antigen for the determination of antibodies against SARS-CoV-2. The test is intended for use as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection.

There appear to be 2 versions of the test, the newer one with an S at the end, which Roche explicitly calls quantitative. I think I was given the fact sheet for the former, but as I said before, if your result has a number, stands to reason it's quantitative.
