Application at 3:30 PM; Pale yellow at 5:30 PM; Trace gray at 7:30 PM; No color 9:00 PM.
The guidelines we have (from an MD instruction sheet) say if color is gone in 4 hours, you have a severe deficiency; 8 hours => moderately low iodine levels. With sufficient levels, the original color remains there for 24 hours. My wife has been taking over 50 mg a day in a supplement. So, is this test valid? Beats me. If the test is valid, she has some sort of absobing problem. We'll have more formal result in a week or so, and will know more.
I have never heard anyone question the validity of the test, but for all I know, everyone flunks it!
