SHBG is a protein made mainly by the liver that carries sex hormones, such as testosterone, in the blood. By binding these hormones, it controls how much of them is active and available to the body. The SHBG blood test measures the level of this carrier protein. It helps doctors understand how much active sex hormone is available, and is often read alongside testosterone levels.

Before the Test

Tell your doctor about all medicines and hormones you take, including birth control pills and thyroid medicines, as these affect results.

Mention if you are pregnant.

Fasting is generally not required.

During the Test

A trained Orange Health Labs professional will collect your sample during the visit.

Follow the instructions given to you at the time of collection.

The sample is labelled and sent to the laboratory for testing.

Let the collection team know if you feel unwell during the procedure.

It is recommended:

To help understand abnormal testosterone results.

To investigate excess hair growth, acne, or irregular periods in women.

To look into low sex drive, fertility concerns, or other hormone-related symptoms in men.

To support evaluation of conditions such as PCOS or thyroid problems.

It can usually be done at any time, often in the morning. Your doctor will advise if timing in the menstrual cycle is important.
