The problem with that test is that it doesn't measure the diurnal variation in cortisol levels. It can't distinguish people with normal total output, but with reversed phase, or those with no diurnal cycling at all. Nor the effect of stressors during the day, which can skew the results.
I don't have faith in those who would try to interpret a daily total cortisol output, when the pattern of output is of diagnostic importance also.
