What Is The Best Time To Get A Testosterone Blood Test Done?

Have you ever heard of someone getting prescribed HREA for low T? Free T levels at 7:30am were 230 and this is what was prescribed yesterday,  but increases the next day.

To understand this change in T levels, we need to know what time of day were the tests were done and what are the best time to check for T levels. 

T is highest between 8-9am. All your test should be done between 8 and 10am. That is the perfect time according to Endocrinologist. T is at its peak then and drops throughout the day.

It's critical that people with doubts get their blood drawn around 8am or by ten at the latest, and that they have two tests on different days and are not sick with a virus or something. Blood levels can drop a substantial amount, as much as 400 ng/dL from dawn to dusk.

E.g. You might have had one come back at 329 "normal" and the recheck could came in at 140. Without the second test, it isn't as convincing to doctors.

Also, getting some blood tests is useful, but if you get something abnormal (less than 500 if you're under fifty), then a full pituitary and sex hormone panel is going to give you the best info to decide what to do.

8-9am based on... What? It may be related to the daylight cycle, your sleep cycle, etc. On 3-13's, overnights, 6pm to 7pm. So a T test at 8am, after you have been awake 16-24 hours...

Based on a specific average wake time? If it's a set time after awakening, that number would be more useful, as not everyone works 9-5 and wakes at the exact same time as everyone else.
