Didnt lie test down
Hi, I completed a rapid test. After 15 mins of the test standing up there was only one control line so negative, I didn’t lie the test down though i only held it up to better lighting to double check. Does that still mean my test is negative? Im panicking now that to activate(probably the wrong wording) the second line if positive it has to be lay down, or is it still a negative while just standing?
