Repeatability of hormone levels in the two samples. Comparison of hormone levels in the two samples. For s-androstenedione, s-testosterone and s-DHEAs the shaded areas represent hormone levels below, within or above normal range in both measurements. For s-17-hydroxyprogesterone the shaded areas represent hormone levels within and above normal range for both measurements. The ICC is reported with the 95% CI. ICC, intraclass correlation coefficient; LLN, lower limit of normal; ULN, upper limit of normal.
