I have a quick question on the TF100 FC/CC drop test. I did a test and forgot to clean the tube out right away and I noticed that after an hour or so the clear liquid turned back to pink. This is normal right? Just want to make sure I am not testing incorrectly. Thanks!

Yes - completely normal. The initial color change is the one you are interested in.

You should be fine. It is advised to take/use the readings immediately after doing the initial drop test to measure FC. Once the liquid is clear, follow-up immediately with the CC test then discard the liquid. Anything you may have left or forgotten about after your testing is invalid and just waste.
