And if you do a retest with the same tube as went blue do you get that blue colour again?

When I test it on the same day it is always a different tube. I suppose I could have chosen the same tube when I retest it on a different day but I would expect that at least once or twice it has happened it would have been a different tube. I don't always use the same tube for PH, same tube for ammonia etc so maybe that could be the issue?
