About the Test

Testosterone is often referred to as “the male sex hormone”, but it is also produced in (and important for) females. In males, testosterone helps regulate sex drive and erectile function, muscle mass and strength, body fat distribution, bone density, and sperm production. In females, the role of testosterone is only partially understood, but it helps produce estrogen and may help regulate how eggs develop in the ovaries. Abnormal testosterone levels in both males and females may result in changes to your overall health and physical appearance.

Testosterone testing may provide insights to men experiencing symptoms of hypogonadism (ie, low testosterone) - which are associated with aging and medical conditions like diabetes, high blood pressure, and obesity. Testing may provide insights to women experiencing symptoms of hyperandrogenism (ie, high androgen levels, like testosterone) – which are associated with medical conditions like polycystic ovary syndrome (PCOS).

With Quest, you can buy a testosterone test online and get testing at a nearby location – no doctor’s visit required.

This test can be taken by people of all sexes and may be right for you if any of the following are true:

You are experiencing symptoms of testosterone imbalance (see Signs & Symptoms section below)
You are planning for a family and want help in evaluating hormones that can impact your fertility
You are a transgender male or female and want to evaluate your testosterone levels
You are monitoring your testosterone levels because you are on hormone therapy (ie, testosterone replacement therapy or androgen deprivation therapy)

Hormone imbalances can only be diagnosed by a healthcare professional based on your symptoms and history. By getting tested and sharing your results, you and your healthcare provider can understand the cause of your symptoms and identify next steps based on your specific medical situation.

Testosterone is an androgen steroid hormone and the principal male sex hormone, but it is also produced in females. In men, testosterone plays a key role in development of the male reproductive system and promotes secondary sexual characteristics such as facial and chest hair and upper body muscular build. It is primarily secreted from the testes. In women, testosterone is secreted in the ovaries and adrenal glands and helps create estrogen and may help regulate how eggs develop in the ovaries.

This test measures total testosterone, which represents all biological pools of testosterone, including the free forms, as well as those bound to proteins in the blood. This test will determine whether your total testosterone level is normal, high, or low.

A testosterone level that is lower or higher than normal can affect the body in many ways. In males, low testosterone levels are more common than high levels. Some males can have abnormal testosterone levels for years without knowing. In females, high testosterone levels are more common than low levels.

Symptoms of low testosterone in males can include:

Decrease in sex drive
Difficulty getting or maintaining an erection
Decrease in muscle mass
Bone weakness
Breast tissue development
Hair loss
Difficulty sleeping
Difficulty with memory and concentration
Decrease in testicle size
Decrease in semen production that can lead to fertility problems

Symptoms of high testosterone in males can include:

Elevated blood pressure
Heart or liver problems
Headaches
Aggressive behavior
Excessive body hair growth
Acne
Prostate enlargement
Decrease in sperm production
Insomnia

Symptoms of low testosterone in females are not well characterized. Symptoms of high testosterone in females can include:

Acne
Hair loss
Increased body or facial hair
Hypertension
Irregular or missing periods
Insulin resistance

As you age, your testosterone level gradually declines — typically about 1% a year after age 30 or 40. For older men, it's important to determine if a low testosterone level is due to normal aging or if it is due to a disease (hypogonadism).*

In women, testosterone is important for muscle health, bone density, energy, mood, fertility, and libido (sex drive). Testosterone levels fluctuate throughout the menstrual cycle, but it remains important throughout life.

How to get your testosterone levels checked, including symptoms of hormonal imbalances, available test options, and how to interpret your results.

When it comes to men’s health, testosterone often gets all the attention. But it’s just one part of a larger, connected system. Overlooked, yet critical: estradiol, prolactin, SHBG, and albumin are also key players. Read the article to learn more.

Testosterone is often thought of as only a male sex hormone, but females have (and need) testosterone too, just in much smaller amounts. Read our article to learn more about essential hormones and how they affect women's menstrual cycles.
