    CYA Test

    Just a quick question. Following directions, they say to put you back to the sun. When I do this as apposed to facing the sun, I get about 5 points difference. Should I block sun out or I'm I being to silly about it? Thanks Bill

    We dont do "5s" here. The best way to get results is the 10's method. Start at the 30, then the 40, then the 50 etc. Only look at the tube after filling to a 10, it makes much more consistant results.

    YOur test results are fine. Do not worry about that tiny difference either way.

    The precision of the test is plus or minus 10 ppm and some say even plus or minus 15 ppm.

    The general advice is to block the sun
