I had made some posts about FRER indents. I decided to test my theory last night by testing the same urine sample with two different boxes of FRER.

One box had clear indents (bad), the other had none visible to my eye. I had a chemical last month (confirmed with beta), so these indents are really disheartening.

Just wanting to put this out there. I’m not sure if these can even be called indents? The “bad” test line is pink.

Photos 2 and 3 are what these “indents” look like under brighter light.
