That is really helpful info so I pressed the informative button - but oooooh what a pretty picture of your little ladies looking so lovely!The issue is specimen collection. Most people are not great at collecting their own specimen. So they tell people to retest. Best practice is to take a good specimen the first time and accept the result.
There are only a couple of reliable tests on the marketplace and to my knowledge only one has actually proven the sensitivity and specificity to be "approved". The rest are still being sold and used under the EUA. It is a dirty little secret that many of them do have equally high false positive as negatives. The package insert for your test should list the sensitivity and specificity. If it does not, then you should question its reliability.
