Not Fasting Before Testosterone Blood Test?

Hello all,

I recently had blood work done and as it was a last minute appointment, I did not fast and my blood was drawn at 1230 in the afternoon. My total testosterone was about 150 points lower than my last test(8 months ago). Is it possible that eating an hour before the rest could have skewed the results?

Thanks in advance!

Getting your blood dawn to late in the day is the reason, you must get it dawn before 10am. Results are useless as T starts dropping after 10am and continues dropping throughout the day.

It really makes that much of a difference?

Your T levels are not static, they fluctuate every hour and everyday. You watch porn an hour later it goes up, you lift weights and days later it goes up.
