What is the normal range for bioavailable testosterone?

Reference Interval

Component Reference Interval
Testosterone, Bioavailable, Adult Male 14-15 years: 10-337 ng/dL 16-17 years: 35-509 ng/dL 18 years and older: 131-682 ng/dL Tanner Stage IV: 40-485 ng/dL Tanner Stage V: 124-596 ng/dL
Testosterone, Percentage Free, Adult Male 1.6-2.9%

How much bioavailable testosterone should a man have?

108-500 ng/dL
Male ≥18 years old

Male ≥18 years old
Free Testosterone 4.5-25.0 ng/dL
% Free Testosterone 1.1-3.0%
Bioavailable Testosterone 108-500 ng/dL

How do you convert nmol l to NG dL?

1 nmol/litre = 28.85 ng/dL.

What is testosterone Bioav calculation?

T = testosterone in nmol/L; SHBG – in nmol/L; Albumin – in mg/dL; Free Testosterone from mol/L to nmol/L, multiply by: 2.88 x 10-13 x 1.6 x 0.003448. Bioavailable Testosterone (nmol/L) = Free Testosterone in nmol/L x (1 + c)

What is considered low bioavailable 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.

Is bioavailable testosterone the same as free testosterone?

Some testosterone is free, which means it is not attached to proteins. Free testosterone and albumin-bound testosterone are also referred to as bioavailable testosterone. This is the testosterone that is easily used by your body.

Why is my bioavailable testosterone low?

In men, low levels of bioavailable testosterone are consistent with primary hypogonadism (testicular impairment) or secondary to a pituitary problem. Andropause in men (decreased libido, erectile dysfunction, muscle weakness, etc.) is caused by secondary hypogonadism associated with aging.

How do you convert nmol to Ng?

To convert ng/ml to nmol/L multiply the ng/ml by 2.5 for example 50 ng/ml is equivalent to 125 nmol/L.

What is the difference between ng/ml and NG dL?

ng/ml↔ng/dL 1 ng/ml = 100 ng/dL. ng/ml↔g/dL 1 g/dL = 10000000 ng/ml.

What is a low bioavailable testosterone level?

What is the difference between total free and bioavailable testosterone?

Historically, only free testosterone was thought to be the biologically active component. However, testosterone is weakly bound to serum albumin and dissociates freely in the capillary bed, thereby becoming readily available for tissue uptake. All non-SHBG-bound testosterone is therefore considered bioavailable.

How can I increase my bioavailable testosterone?

Vitamins and Supplementation Specific vitamins and minerals may be beneficial in boosting testosterone levels. Research has shown that zinc, vitamin d and vitamin b supplements increased sperm quality by over 70%. Zinc has shown to help boost testosterone levels in athletes.
