What is the normal free testosterone level pg mL?
Free testosterone levels are measured by picogram/milliliter. Normal free testosterone levels vary from a range of 9.3-26.5 pg/mL for men aged 20-29, to 6.6-18.1 pg/mL for men 59 and older. For middle-aged men (between the ages of 40-49) the normal range is 6.8-21.5 pg/mL.
What is normal free testosterone pmol L?
American consensus statements say above 11.1 nmol/L is normal, below 6.9 nmol/L is diagnostic of hypogonadism, and 6.9–11.1 nmol/L is equivocal.
How do you calculate free testosterone from testosterone?
Therefore, in routine clinical practice, free testosterone can be calculated assuming an albumin concentration of 43 g/L (6.2 x 10-4 mol/L), only requiring input of measured values for total testosterone and SHBG.
How do you convert testosterone from nmol L to ng mL?
The conversion factors are:
- 1 nmol/litre = 28.85 ng/dL.
- 1 pmol/litre = 0.2885 pg/mL.
What is a low level of free testosterone?
Generally, most experts would agree that a total testosterone level less than 250 ng/dL is considered low, whereas some experts endorse a higher level of around 350 ng/dL as the lower limit of normal.
What is a healthy testosterone level by age?
But by 15 to 16 years old, the ng/dL should be 100-1,200. Late Teens: Anyone between 17 to 18 years old should have testosterone levels between 300 and 1,200 ng/dL. Adults: An adult (19 years and older) should have anywhere between 240 and 950 ng/dL.
What is normal range of testosterone?
Testosterone levels are measured through blood tests. Most doctors agree that a “normal” reading falls anywhere between 300 to 1,000 nanograms per deciliter (ng/dL). About 40% of men over age 45 will have levels that come in below that range. But a low reading by itself isn’t enough to warrant alarm.
What is a normal testosterone level NHS?
The NHS, and most other healthcare experts consider normal testosterone levels to be between 10 and 30 nmol/L, although depending on the lab doing the test, the normal levels can vary slightly. Levels lower than 10 nmol/L could be a sign of ongoing low testosterone levels.
What percentage of testosterone is free?
Approximately 98% of the testosterone the body produces is bound to either sex-hormone binding globulin (SHBG), or albumin. This is referred to as “bound testosterone.” The 2% that’s left is known as “free testosterone.”
What is considered low free testosterone?
The American Urology Association (AUA) identifies low blood testosterone (Low-T) as less than 300 nanograms per deciliter (ng/dL). These symptoms or conditions may accompany Low-T: Low sex drive. Fatigue.
How do you convert pmol L to nmol l?
pmol/l↔nmol/l 1 nmol/l = 1000 pmol/l.
What is more important free testosterone or total?
Total T should be the first test ordered in the workup for hypogonadism. Free T is most useful when there is a reason to suspect that the sex hormone- binding globulin level is abnormally decreased, leading to potentially falsely low total T readings. This may occur particularly in older or obese patients.
What does pg/mL mean on a testosterone test?
Some laboratories measure free testosterone levels pg/mL by age – pg/mL meaning picograms per milliliter. Other labs use ng/dL – nanograms per deciliter, which is what our charts on this page will show.
What is the normal range of free testosterone in males?
Free testosterone Males 0-9 years Less than 1 pg/mL 10-11 years Less than 4 pg/mL 12-13 years Less than 68 pg/mL 14-15 years 2-95 pg/mL 16-17 years 26-119 pg/mL 18 years and older 32-168 pg/mL Tanner stage I Less than 3 pg/mL Tanner stage II Less than 15 pg/mL Tanner stage III Less than 68 pg/mL Tanner stage IV 24-117 pg/mL Tanner stage V…
What is the difference between nmol/L and free testosterone?
WeightTraining.NZ Conversion : nmol/L to ng/dL ng/dL to nmol/L Total testosterone : nmol/L Free testosterone : pmol/L
What is a normal testosterone level for a 40 year old?
Testosterone levels in men over 40. Free: 6.8 – 21.5 pg/mL. Total: 201 – 993 ng/dL Normal 500 – 550 ng/dL. Testosterone levels in men over 50. Free: 7.2 – 24.0 pg/mL. Total: 170 – 918 ng/dL Normal 400 – 450 ng/dL. Testosterone levels in men 60 and ove r. Free: 6.6 – 18.1 pg/mL.
