Testosterone Tests: How It’s Done, Levels, and Results

Testosterone Levels Test: MedlinePlus Medical Test

A doctor may order different tests based on what they suspect the issue is. As discussed above, testosterone’s primary role in women is to convert into estradiol. However, testosterone also influences primary and secondary sex characteristics such as clitoral size and breast development. Additionally, there is a rise in testosterone during ovulation, when the egg is released during the menstrual cycle. T is the prototypical male hormone, though it is also produced in females. In females, 25% of T is produced in the ovaries, 25% in the adrenal glands, and 50% in the peripheral conversion of androgen precursors. T is metabolized to dihydrotestosterone (DHT) and estradiol (E2) in both males and females.

Health professionals use LH and FSH readings to explore a possible cause of low testosterone and diagnose hypogonadism. Bioavailable testosterone includes testosterone that is free or loosely attached to albumin. Because of this, free testosterone is theorized—although still debated—to be a good proxy for how much of your testosterone is actively working. Measuring your SHBG level provides information about how much of your testosterone is active. Only testosterone that is free or attached to albumin is considered available for use.

The most precise FT assay requires liquid chromatography-tandem mass spectrometry (LC-MS/MS) and equilibrium-based dialysis methods (test code 36170). A healthcare professional should discuss your testosterone test results with you. If not, we encourage you to prompt such a discussion; it is important to understand how your results relate to your symptoms, general health, and long-term disease risk. Free testosterone is the amount of the hormone that’s readily available for the body to use. Bound testosterone is attached to proteins like sex hormone-binding globulin (SHBG) and albumin, which transport it through the body. If your doctor is drawing your blood—and potentially treating you for low T—make sure they’re board-certified and specialize in men’s health.

For males who have gone through puberty, the test is mostly used for symptoms of low T levels (testosterone levels which are too low). But other health issues may also cause low T, such as thyroid problems, long-lasting illness, or problems with the testicles. You may need this test if you have symptoms of abnormal testosterone levels.

Studies have shown that lack of sleep may lead to lower testosterone levels. In women, testosterone is made in the ovary from the prohormone DHEA (made in the adrenal glands). Testosterone is converted into estradiol, one of the primary female hormones. In fact, ovaries produce three to four times more testosterone than estrogen, making it the true dominant hormone in women.

Additionally, all participants were closely monitored to adhere to a uniform diet plan. The participants were instructed to follow the same exercise regimen at the same time of day, with samples collected in the morning to mitigate the impact of natural hormone fluctuations throughout the day.

Another symptom that may warrant a testosterone level check is fatigue or a general decrease in energy levels. Testosterone helps regulate metabolism and energy production, so low levels of testosterone can lead to feelings of fatigue or tiredness even after sufficient rest. If an individual is experiencing unexplained fatigue despite adequate sleep and other lifestyle factors, it may be beneficial to check testosterone levels. It is worth noting that testosterone levels can vary throughout the day, with the highest levels typically occurring in the morning.

Testosterone is the primary male sex hormone responsible for numerous functions within the body. From regulating bone density and muscle mass to influencing sex drive and mood, testosterone plays a crucial role in overall well-being. However, fluctuations in testosterone levels can have significant impacts on health. That’s why it’s important to have an understanding of the different tests available to check testosterone levels. These tests can help diagnose hormonal imbalances, monitor treatment effectiveness, and identify potential underlying health issues. Whether it’s a blood test, saliva test, or even a urine test, there are various options to accurately assess testosterone levels and ensure optimal health. Hormonal balance, including optimal testosterone levels, is pivotal in preserving overall health and well-being across various physiological systems.

Testosterone is known as a “male” sex hormone, but females have testosterone in smaller amounts. If your testosterone levels are too low or high, you might develop symptoms that interfere with your daily life. A simple blood test can help you determine if your levels are in the normal range, which is 300–1,000 ng/dL for men and 15–70 ng/dL for women. Treatments are available if your testosterone levels are abnormal.

The sample is sent to a lab, and results are available within days. A health professional uses a needle to take a blood sample, usually from the arm. There are different forms of testosterone in your blood that may be measured to help diagnose certain health problems. The proteins prevent your tissues from using the testosterone right away, which helps control the amount of “active” testosterone in your body. Testosterone that’s not attached to proteins is called free testosterone vs serum (kekkekamperen.nl) testosterone. Addressing high testosterone could include considering medications, exploring the underlying cause (such as tumor removal), and making healthy lifestyle adjustments. Increased muscle mass, mood changes, and fertility problems are common.
