SHBG slightly elevated

[Scout4answers]

Any thoughts on why SHBG is slightly high?

Sex Hormone Binding Globulin Your Value=78 nmol/L

ComponentYour ValueStandard Range

Testosterone, Free, Calc<1 pg/mL

47 - 244 pg/mL

INTERPRETIVE INFORMATION: Testosterone, Free Calculation

Free testosterone concentration is calculated using total

testosterone (measured by immunoassay) and the binding constant of

testosterone and sex hormone-binding globulin (SHBG). Testosterone

immunoassays are both imprecise and inaccurate at low testosterone

concentrations, such as those found in children and cisgender

females. For these individuals, testing by mass spectrometry is

recommended; refer to Testosterone, Free (Adult Females, Children,

or Individuals on Testosterone-Suppressing Hormone Therapy) (ARUP

test code 0081059).

For individuals on testosterone hormone therapy, refer to

cisgender male reference intervals. No reference intervals have

been established for males younger than 14 years or for cisgender

females. For a complete set of all established reference

intervals, refer to ltd.aruplab.com/Tests/Pub/0070109.

Testosterone, Adult, Male<3 ng/dL

300 - 720 ng/dL

INTERPRETIVE INFORMATION: Testosterone by Immunoassay

Testosterone immunoassays are both imprecise and inaccurate at low

testosterone concentrations, such as those found in children and

cisgender females. For these individuals, testing by mass

spectrometry is recommended; refer to Testosterone (Adult Females,

Children, or Individuals on Testosterone-Suppressing Hormone

Therapy) (ARUP test code 0081058). Free or bioavailable

testosterone measurements may provide supportive information.

For individuals on testosterone hormone therapy, refer to

cisgender male reference intervals. No reference intervals have

been established for males younger than 14 years or for cisgender

females. For a complete set of all established reference

intervals, refer to ltd.aruplab.com/Tests/Pub/0070130.

Testosterone, Bioavailable<1 ng/dL

131 - 682 ng/dL

INTERPRETIVE INFORMATION: Testosterone, Bioavailable

Bioavailable testosterone concentration is calculated using total

testosterone (measured by immunoassay) and the binding constant of

testosterone and sex hormone-binding globulin (SHBG) and/or

albumin. Testosterone immunoassays are both imprecise and

inaccurate at low testosterone concentrations, such as those found

in children and cisgender females. For these individuals, testing

by mass spectrometry is recommended; refer to Testosterone,

Bioavailable and Total, Includes Sex Hormone-Binding Globulin

(Adult Females, Children, or Individuals on

Testosterone-Suppressing Hormone Therapy) (ARUP test code

0081057).

For individuals on testosterone hormone therapy, refer to

cisgender male reference intervals. No reference intervals have

been established for males younger than 14 years or for cisgender

females. For a complete set of all established reference

intervals, refer to
