Hormones are responsible for everything from regulating your mood to helping the body break down food. A hormone imbalance can cause serious health problems.
The most common test for testosterone is a blood test taken from the arm in the morning before 10 a.m. The test measures the amount of testosterone bound to proteins in the blood.
Testosterone is a male sex hormone and androgen that helps male features develop during puberty, such as a deeper voice and more muscle mass. It also boosts libido and contributes to reproductive functions, and it’s an essential component of many bodily processes in both men and women.
A testosterone blood test measures the concentration of this hormone in the blood. It can reveal whether a person has low or high levels of this hormone.
A health professional uses a needle to take a sample of blood from the arm or scrotum for testing. The process is quick and painless, with most people feeling a slight sting or pinch. The sample is then sent to a laboratory for analysis. The results typically arrive within a week, with some companies offering same-day turnaround.
Testosterone, the major androgen in men, is essential for male development and function. It helps boys develop masculine features like facial and body hair, a deeper voice, and muscle strength; it maintains adult secondary sexual characteristics and sperm production; and regulates gene expression in most extra-genital tissues.
In adults, testosterone levels decline slowly throughout life, dropping by about 1 percent a year after age 30. Low testosterone can contribute to a variety of symptoms, including loss of muscle strength, decreased energy and libido, erectile dysfunction, changes in mood and memory problems.
A blood test is the best way to measure total testosterone in your body. A reference laboratory will typically use liquid chromatography tandem mass spectrometry (LC-MS), which measures both protein-bound and free testosterone. A serum sample is diluted to separate the protein-bound and free hormones. Equilibrium dialysis is then performed overnight against buffer or an albumin solution, or more rapidly using centrifugal ultrafiltration cartridges; the unbound steroid H3-testosterone is measured by LC-MS.

Testosterone is essential to the male sex hormone system. It helps to build muscle mass, maintain a healthy weight, support normal cholesterol levels and reduce inflammation. It also regulates sex drive and helps to achieve and maintain an erection. Low testosterone has been linked to reduced sex drive, infertility and depression.
Testosterone levels increase during puberty and reach a peak in the late teen years. Then, the hormone begins to decline gradually until it reaches a low point in adulthood.
While there is no way to reverse natural declines in testosterone, there are steps that can slow the process and help you feel your best. Some of these include exercise, getting enough sleep and limiting alcohol. Some supplements may also help boost testosterone.
One of the best ways to increase testosterone is by taking a supplement such as Testogen, which contains D-Asp. D-Asp stimulates LH, which triggers the Leydig cells in the testes to produce more testosterone. It also includes fenugreek extract, which contains furostanolic saponins that inhibit the enzymes that convert testosterone to estrogen.
Many at-home testing kits are available for a blood or saliva sample. A person should carefully read the kit description to see what biomarkers it tests for. A person should also look at a company’s reputation and what it says about a sample collection method, as some home test kits require fasting before the procedure.
Most tests measure total testosterone, which includes both free and attached testosterone. But a few tests may focus on measuring only free testosterone. To do this, a tracer is added to the sample and it’s allowed to partition into compartments containing the testosterone and binding proteins. After reaching equilibrium, a centrifugal ultrafiltration accelerates the dialysis and free testosterone passes through a semi-permeable membrane into a second compartment containing the tracer and a buffer solution.
Most blood tests need to be taken on an empty stomach, so a person should check with their doctor or the pathology collection centre about when they can have food and what they should avoid. Some test results may also vary between laboratories.
