So when doing the TA test with the test kit it seems that my color switched to pink, not red as the directions suggest. Should I stop adding regent at the bright pink color and call that red? Mine doesn't seem to ever get to red. I was at 30 drops the other day- today I'm at 14 drops and it is just bright pink. Advice?? Will it ever actually turn true red? It seems like I will use the entire bottle to run one test if I am truly waiting for a "red" color.
