Generally, the earlier upon waking, the better--
--as daytime activity, especially exercise, can skew the results of the test. When the test is being done, good labs will tell you to stay very still in between draws--no walking around, and certainly no heavy physical activity (and no eating until the test is over--so most labs want to start the test very early to avoid low blood sugar readings from too long a fasting period).
