Testosterone test (Blood)

Testosterone Test via Blood

Testosterone is the primary androgen hormone, produced mainly in the testes in men and in smaller amounts in the ovaries and adrenal glands in women. It plays an essential role in regulating sexual function, fertility, muscle strength, bone health, mood, and overall energy balance.

Why measure testosterone?

Abnormal testosterone levels can affect both men and women. Low testosterone in men may cause reduced libido, erectile dysfunction, fatigue, loss of muscle mass, mood changes, or infertility. In women, low levels may contribute to reduced energy, low libido, or decreased bone density, while high levels are often associated with symptoms such as irregular cycles, acne, or excess hair growth (hirsutism). Measuring testosterone can therefore provide valuable insights into reproductive health, hormone balance, and overall wellbeing.

If you want a more complete overview of your hormonal health, it can also be helpful to assess your thyroid function, for example with the Thyroid TSH Test, as Thyas thyroid hormones play an important role in metabolism, energy levels, and hormonal balance. For a more comprehensive evaluation of testosterone and related hormones, you may also consider the Testosterone Test Plus, which provides deeper insights than a standard testosterone measurement.

Symptoms of testosterone imbalance

• Low testosterone in men: decreased sexual function, low energy, mood swings, loss of strength or muscle mass, increased body fat, infertility.
• High testosterone in women: irregular periods, acne, hair thinning on the scalp, increased body or facial hair, possible links to polycystic ovary syndrome (PCOS).
• Low testosterone in women: fatigue, reduced libido, mood changes, and weakened bone health.

When is testing relevant?

Testing may be considered if you experience unexplained fatigue, reduced sexual function, fertility problems, mood disturbances, or symptoms suggesting hormonal imbalance. It may also be useful for individuals undergoing hormone therapy, athletes monitoring performance-related health, or women being evaluated for PCOS.

Key benefits of the Testosterone Test (Blood)

• Measures total testosterone directly in blood
• Relevant for both men and women
• Supports the investigation of symptoms such as fatigue, infertility, low libido, or irregular cycles

How the test works

The Testosterone Test (Blood) is performed using a simple dried blood spot (DBS) sample collected at home with a finger prick. The sample is sent to our accredited laboratory for analysis, and results are delivered digitally, giving you secure and convenient access to your hormone health insights. For those who prefer a non-invasive option, GetTested also offers a saliva-based testosterone test.
