Fragen und Antworten zu Sexualhormon-bindendes- Globulin (SHBG)
What is the respective laboratory value?
SHBG is a protein that binds sexual hormones such as testosterone and estradiol in the blood. The laboratory value measures the concentration of SHBG in the blood, which influences the free portion of these hormones.
For whom is such a test to be considered?
A SHBG test is recommended for: • Men with symptoms of low testosterone levels (e.g. loss of libido, muscle weakness) • Women with suspected androgen excess (e.g. acne, hirsutism, PCOS) • Patients with liver diseases, as the liver produces SHBG • People with thyroid disorders, which can affect SHBG
What is it used for?
The test serves to clarify hormonal disorders and is often measured together with testosterone or estradiol to calculate the free hormone level. It helps to clarify the cause of symptoms such as infertility or androgen excess.
What can be inferred from that?
A high SHBG value can lead to a lower free testosterone level and is often observed in: • Liver diseases • Hyperthyroidism • Intake of estrogens (e.g. in the birth control pill). A low value indicates an increased free testosterone level, as in PCOS, obesity or insulin resistance.
What is the ideal time for a test?
The testing can be carried out at any time of the day and is independent of food intake.
Particularly interesting?
• SHBG is often used to calculate the free androgen index (FAI), which indicates the ratio of testosterone to SHBG. • Changes in liver function, thyroid function, and insulin resistance strongly influence SHBG levels. • The test is particularly helpful in diagnosing androgen disorders in women.
