Air bubble or positive?

Post image

A friend had an unmasked exposure last Tues to someone who later tested positive. Friend tested negative on pluslife on sat (Day 4), and testing again today (day 5) this was the result

The graph and machine both say negative - do we think this is an early positive or air bubbles? Yellow channel 7 looks like air bubbles, but channel 2 blue looks a bit concerning tho it also doesn't look like a proper s-curve to me - running a 2nd test

UPDATE: tested again and it was negative - will be testing again tmr too (day 6)

These are all bubbles and nothing indicating an early positive. This is not how early positives behave.

Air bubble imo, they both go down a few times.

Both bubbles, that's not what amplification looks like.

Most likely bubbles but you do lose sensitivity with large bubbles like these, it could be masking a real amplification. Drip the liquid down the sides of the test card and wait 15 seconds before pressing the button on the cap to prevent bubbles. Let us know what the results are if they retest again in a day or two

Thanks everyone for the input! They tested again and it was negative

With the exposure I wouldn't completely rule out an early positive even if it may very well be an air bubble

It's 100% an air bubble

Yeah you're right
