Re: Free testosterone ng/dL to pg/ml?

[Guest guest]

I believe you multiply number of units by 10 to go from ng/dL to pg/dL. Then

12.1 ng/dL = 121 pg/dL. See if that sounds right.... If I am wrong someone

please correct.

Using LabCorp's ranges, Free T has a range of 5-21 ng/dL while total T is

241-827 ng/dL. You will see that free T is around 2% of total which I believe

is the normally considered value.

I was actually looking for a conversion to pg/ml.

This is one example of free T ranges I found .

Reference Intervals for Free Testosterone from LabCorp

* 20-29 years 9.3-26.5 picogram/mL

* 30-39 years 8.7-25.1 picogram/mL

* 40-49 years 6.8-21.5 picogram/mL

* 50-59 years 7.2-24.0 picogram/mL

* 60+ years 6.6-18.1 picogram/mL

I'm just wondering where I fall. My total T was 327 ng/dL and my free T was 12.1

ng/dL

ng to pg is a factor of 1000 (to get ng divide pg by 1000, to get pg multiply ng

by 1000)

from this link.

I found that link last night before I posted but there is so much conflicting

info. in it so I had to ask here.

So to get ng to pg you multiply by 1000 but then you still have to convert from

dL to mL.

Going by this Dr's response:

" You asked originally:

I want to convert 122.3 pg/ml to ng/dl.

A pg or picogram is 1/1000 of a nanogram. Therefore 122.3 pg/ml would be 0.1223

ng/ml.

ng/dl means ng per 100 ml. Therefore to convert 0.1223 ng/ml to ng/dl you would

multiply by 100 to get 12.23 ng/dl. "

I would take 12.1 ng/dL / 100 to get .121 ng/mL. Then I take .121 ng/mL x 1000

to get 121 pg/mL.

121 pg/mL makes no sense in any of the free T ranges I've seen. I think my

results are screwed up and possibly my free T # is already in pg/mL.
