In any case, want to hear from DDF -
Vaxxed, had minor cough, yesterday went to Chai and tested positive on rapid, isolated, received back negative PCR result this morning. Went to Chemed today and tested negative on rapid, awaiting PCR (after shabbos).
Chai told me (upon receiving positive rapid) that negative PCR won't clear me since they went further up nose for the rapid.
Chemed person behind the counter told me I'm good to go even without another test.
The nurse who gave the test seemed to think similar and said that I'm good if the rapid comes back negative (which it did).
I think official health policy is 2 negative PCR's, 24 hours apart.
@ShimshonK I'm trying to read various recommendations, and it's confusing. This is my best guess, but look at the sources below.
Vaxxed, 7 months ago.
Symptoms - only a cough. (no headache, congestion, fatigue, nausea, fever)
You don't have personal physician
I assume:
Symptoms began within 3 days prior (Tues, Wed or Thurs)
You're in your 20s or 30s (because if you were older you'd probably have a personal physician)
After a positive on rapid test, should isolate until get results from PCR. PCR used to confirm rapid test results should use "specimens with evidence of the most sensitivity, such as nasopharyngeal or mid-turbinate swabs," that is, from all the way up the nose.
It sounds like Chai is saying that they didn't do that, that is, that they took the PCR specimen from lower down. Does that sound like what you felt? Did Chemed take the PCR test from all the way up? If you think that the Chai PCR may not have been taken properly, but that the Chemed test was, then it makes sense to continue to isolate over Shabbos, till you get the results of the second, more accurate, PCR. And if that's also negative, then one would assume that the first rapid result was a false positive, so you can rejoin society.
I don't see anything recent about 2 tests separated by 24 hours, and I'm wondering whether that might have been the policy last year, when the initial tests were less accurate.
But this is where it's confusing: All this is predicated on the assumption that you did not have close contact with someone who is known to have a covid-19 infection. If you did have such a contact (or if you find out retroactively that someone you were near has since become ill) then the recommendation is to count 5 days after that contact before getting a test. That is, it can take 5 days for the PCR to turn positive, so if, for example, you were near an infected person on Tues, it's possible that you were infected but the PCR would be negative on Thurs, Fri, and only turn positive on Sunday. So if you have reason to think that you had close contact over yuntif with someone with covid, then perhaps you should continue to isolate and have an additional PCR on Sun/Mon.
