T Levels

[Aido]

Hi all, new here and first post so be gentle please :3

I'm trying to find out what the normal range of testosterone should be? I've gotten different results from searching online, some sites have it around 300-1000, then there's others that are 35-89. I figure it's a different way of measuring it depending on the country (I'm in Ireland) so I'm just wondering if anyone knows what it is?

Depends, total testosterone or free testosterone?

That 300-1000 range is total testosterone, which is what most doctors look at.

You can find a break down here.

There are 2 ways to measure T levels: nmol/l which I think is the higher number and ng/ml which is the lower. I found the normal levels both way but I don't think I can help you cause I'm in Hungary and the numbers are different here what you wrote.

Thanks, but gonna have to ask my doc methinks. I'm on T two months now. Pre T my results were 1.6,I  rang my doctor about my results from a few days ago and all she told me was that they are 52. Not sure if it's total or free she meant. Seems very low to me, but I don't know how we measure it here

Hi ado, cut and paste right off my blood screens, done last week:


As nanomoles per litre (nmol/L) the normal range is (9.9-27.8 ) nmoles/litre....

A nanomole is 1X10-9 moles per litre.

A mole of testosterone weighs 288.4244 g/mol.  So, 9.9 to 27.8 nmoles/litre corresponds to:

(9.9 X 288.4244)/1,000,000,000 grams/litre to (27.8 X 288.4244)/1,000,000,000 grams/litre or

0.002855 miligrams/litre to 0.008018 milligrams/litre.

How much do you weigh in Kilograms?  Multiply each number to get range in the total weight of testosterone in your body....(because the density of our bodies is roughly 1 kilogram/litre - that's why you float when you hold your breath and sink when you exhale, in the water)...

Now I'm even more confused  Best to just go through it with the doc, the only results I've seen (the first ones) just had tesosterone - 1.6 written on it so no idea about the rest of it.

High Ado.....do u have the path screen handy....does it have the units of measure on the number?  If u post that, I can convert for u...

kind Regards
