58% to 71% range I saw prior to omicron which it has been said to be less effective. They small study showed it was extremely unreliable early on when PCR was basically 100%. At any rate, you all asked and I provided.Your anecdotal account notwithstanding, "reliability" is a relative term; like everything else concerning COVID it is a matter of probabilities, and new information is constantly coming in. For a test to be worthless its reliability would have to be on the order of 50% (i.e., wrong as often as right). Rapid testing may not be 100% (nothing is) but it is much better than 50%.
