Hi. I'm 24 years old. I want to ask about my serum total
testosterone. I've done this examination two times in early morning. First reading was 6 ng/ml Ref range (1.3-7.7) .. second was 6.2 ng/ml ...Ref range (2.4-8.3) ... it seems in the upper normal range.. Should I be concerned about it.. or everything seems normal.? Thank you in advance..
