I just checked and I, a 62 year old man, had a level of 120 nmol/L .
I read this could be low for a couple reasons.
That I was stressed at time of blood draw. Or a sign of a low adrenal glands.
The test was done when I was in severe pain, Decompressed disk and the effects of multiple rib fractures. Plus the uses of narcotic pain medication. Most likely not an accurate testing time.
