Testosterone levels in males and females ; Total testosterone Stage Age range Male Female Values SI units Values SI units ; Infant: Premature (26–28 weeks) 59–125 ng/dL: 2.047–4.337 nmol/L
A 2011 Institute of Medicine (IOM) report set the sufficiency level at 20 ng/mL (50 nmol/L), while in the same year The Endocrine Society defined sufficient serum levels at 30 ng/mL and others have set the level as high as 60 ng/mL. [89] As of 2011 most reference labs used the 30 ng/mL standard. [63] [89] [90]: 435
Serum 25(OH)D concentration is used as a biomarker for vitamin D deficiency. Units of measurement are either ng/mL or nmol/L, with one ng/mL equal to 2.5 nmol/L. There is not a consensus on defining vitamin D deficiency, insufficiency, sufficiency, or optimal for all aspects of health. [19]
Hormones predominate at the left part of the scale, shown with a red at ng/L or pmol/L, being in very low concentration. There appears to be the greatest cluster of substances in the yellow part (μg/L or nmol/L), becoming sparser in the green part (mg/L or μmol/L).
Reference ranges for blood tests of plasma renin activity can be given both in mass and in international units (μIU/mL or equivalently mIU/L, improperly shown as μU/mL or U/L, confusing mcU/mL used where Greek μ not available), with the former being roughly convertible to the latter by multiplying with 11.2. [3]
A broad reference range of 20 to 150 nmol/L (8-60 ng/mL) has also been suggested, [16] while other studies have defined levels below 80 nmol/L (32 ng/mL) as indicative of vitamin D deficiency. [ 17 ] Increasing calcifediol levels up to levels of 80 nmol/L (32 ng/mL) are associated with increasing the fraction of calcium that is absorbed from ...

100–200 pg/mL <55 ng/dL [4] Callen-Lorde: United States "Some guidelines recommend checking estradiol and testosterone levels at baseline and throughout the monitoring of estrogen therapy. We have not found a clinical use for routine hormone levels that justifies the expense.
