Read the bolded. Jeez. |
| I like how half the posters on this thread got the isolation period wrong. |
It's nice in practice. The rapid tests don't really have false positives, and if you test positive on one, you are very likely infectious. They aren't like PCRs where you can test positive for weeks or months. If you're testing positive on a rapid test, you should stay home. |

Here's the most recent school guidance from DC Health:

HAHAHAHAA oh my god that is the most false statement I've seen in a while. |
I'll amend: I've known two instances where people got false positives from required asymptomatic rapid antigen tests. In both instances, the later PCRs showed negatives. In one case, the false positive shut down a classroom, until the PCR result came in (and the school accepted the follow-up PCR). Fortunately the school allowed the PCR result, rather than sticking with the rapid antigen. But yes, I do grant that false positives are more likely with PCRs than with rapid antigens, and false negatives are more likely than false positives in rapid antigens. |

BMJ wiki on false positives. Even with a 99.9% test specificity (like for rapids), you still get a high percentage of your positives being false positives. For example, stick in a 44% test sensitivity (like for rapids in asymptomatic individuals) and a 99.9% test specificity, with a true positivity rate of 1%. You get 23% of your positives are false positives.

Isolate for five days, test on Day 6 with rapid test. Return to school with negative rapid. |
right? that "really" is doing a looooot of work there. |
This is correct. Though my 6 year old didn’t test negative until around day 8 of isolation, FYI. |

For returning to school after testing positive, are people using the at-home rapid antigen tests or do you have to go somewhere for the rapid antigen test?
Also if your kid tested positive on day 5, then do you keep testing each day or do you stay at home until day 10 and then return? If stay at home until day 10, do you test again or do you just return to school on day 11? I appreciate this chart, but there are some things that are still not clear to me. https://osse.dc.gov/sites/default/files/dc/sites/osse/page_content/attachments/Return%20to%20School%20Criteria_1Pager_April22.pdf |
