FYI If the Control line on your test (Next to the “C”) is very faint, it may be near expiring or otherwise not reliable. If I had the test in the image below, I’d consider it defective and would get a different one.

To be clear though - if the “T line” is showing up, consider it a true positive even if the C line is faint. But if the C line is faint and there is no T line… this should not be reliable as a “negative” result
@michaelmina_lab This test was just done (expiration date is 10/23/23) but it’s what we have. The control line is faint and the sample line is strong. Would this be considered positive?
@michaelmina_lab I have found that tests that arrived during a heat wave seem not to work (no C line) even if well within expiration date. Probably kept in a hot truck too long.
@michaelmina_lab You mean big % of tests that handed out for free by gov’t? Have to wonder if anyone who approved mass mailer in August looked at the expiration dates given the White House projected 100M infection surge that now pretty much looks like a guarantee. False negatives will skyrocket
@michaelmina_lab @DaliaHasanMD VERY GOOD QUESTION ⁉️
@michaelmina_lab This is great, you have non science ppl doing these tests. Exactly, it's a control for that reason. Measure your result against the control. Lets you know if your reagents are working properly
@michaelmina_lab Many people I’ve chatted with found their initial positive test result was faint subsequent tests were much darker, my experience was the same not sure if that’s just coincidence…
