What is testosterone bioavailable?
Testosterone bound to sex hormone binding globulin (SHBG) is tightly bound and is essentially inactive. Bioavailable testosterone (BT) refers to both free testosterone and that which is bound to albumin.

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.
What is low testosterone bioavailable?
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.

What percentage of testosterone is bioavailable?
Only 2-3% exists in free, biological active form. Testosterone is weakly bound to albumin and can be reversed easily, therefore albumin bound and free testosterone are considered to be bioavailable testosterone….Male ≥18 years old.
| Male ≥18 years old | |
|---|---|
| % Free Testosterone | 1.1-3.0% |
| Bioavailable Testosterone | 108-500 ng/dL |
What is testosterone free bioavailable and total MS?

What is free testosterone direct LC?
The Testosterone Free and Total LC/MS-MS test provides two measurements for Testosterone levels. Results for this test will include Free Testosterone and Total Testosterone measured by liquid chromatography and tandem mass spectrometry (LC/MS-MS). Testosterone is the primary male sex hormone.
Is total testosterone the same as bioavailable testosterone?
The total quantity of albumin-bound and free forms is called “bioavailable testosterone.” Total testosterone is the sum of the three forms of testosterone.
What is the CPT code for a testosterone test?
Testosterone, Total, Males (Adult), Immunoassay All test requests for Testosterone on female and pediatric (<18 years) patients must use test code 15983 – Testosterone, Total, MS.
How is the concentration of free and bioavailable testosterone determined?
The concentrations of free and bioavailable testosterone are derived from mathematical expressions based on constants for the binding of testosterone to albumin and/or sex hormone binding globulin. Days of the week the test is performed. Expected turnaround time for a result, beginning when ARUP has received the specimen.
