Time of day to measure test?

[Killler]

The lab tells me it doesn`t matter when the blood is taken and if you have eaten before hand.

Is this true?

All the ones I've done require to fast for 8 to 12 hours , optimum time to check test levels is between 6 and 8 a.m

I have also head that T peaks when you wake so the best time is early morning. I don't know if fasting matters

Fasting doesn't matter just tell your doctor to take a non fasted blood test.... But personally I prefer to take it fasted I think it's more accurate but I could be wrong

 

[stevesmi]

fasting only matters obviously if you are interested in seeing your glucose results. so what if its included I would go into it with a normal breakfast and plenty of water like usual. just ignore your glucose results

you want to get it done before 8am..

Morning. Around 7am. That's when your test is the highest. It starts to decline after that.

pretty much doesn't matter, unless cholesterol/blood sugar is tested

Not true. T levels are highest in the morning.
Google circadian rhythm of testosterone.

Thanks for the answers guys,I`ll probably go measure it in the morning,but I don`t care about the little daily oscillations,just want to see if my test is horribly low to begin with.

They aren't necessarily little fluctuations. In this study, the average variation was 420 low to 577 high throughout a day.
