The Testosterone Panel test is a comprehensive screening that measures the levels of testosterone, a key hormone responsible for various bodily functions like muscle mass, bone density, mood, and sexual health. This test helps identify any imbalances in testosterone levels, aiding in diagnosing conditions like hypogonadism, infertility, or hormone-related disorders. By assessing testosterone levels, this panel provides valuable insights for healthcare professionals to recommend appropriate treatments and optimize overall well-being.

Testosterone is classified as an androgen, a type of steroid hormone. Leydig cells in the testicles produce testosterone in males, while females generate it in their ovaries and adrenal glands. This hormone plays a crucial role in male reproductive system development, activates sexual drive, enhances sperm production and potency, and influences the psychophysiological aspects of sexual behavior. Three types of total blood testosterone are free, mixed with sex hormone-binding globulin, and albumin-bound testosterone. Free and weakly bound testosterone are considered bioavailable and have biological activity. On the other hand, bound testosterone is inactive. The concentration of sex hormone-binding globulin does not affect the level of free testosterone. Therefore, testing for free testosterone is more informative than total testosterone when SHBG concentration is elevated or reduced due to conditions like hyperthyroidism, cirrhosis, obesity, androgen excess, pregnancy, and others.
The identification of causes for early or delayed puberty in male individuals, as well as impotence and infertility issues in men. Diagnosis of tumors producing testosterone in the reproductive organs and detecting polycystic ovaries and other causes of virilization in females. Monitoring prostate cancer treatment using GnRH analogs and antiandrogens and identifying acne causes. Evaluation of the endocrine system function and diagnosis of hypothalamic-pituitary disorders. Additionally, clarification of the sex of newborns with ambiguous sexual characteristics. The study is scheduled for men with delayed development of secondary sexual characteristics or early puberty, decreased sexual desire, impotence, suspected hypogonadism, infertility, andropause, severe acne, and osteoporosis. The study is scheduled for women with irregular menstrual cycles or absence of menstruation, infertility, hirsutism, excessive development of male external signs, and acne. In the case of newborns with unclear sexual characteristics, the study may be conducted alongside other methods to determine the levels of sex hormones and other diagnostic procedures.
It is recommended that testosterone testing be conducted during the morning hours between 7 a.m. and 10 a.m. when levels are typically at their highest. In some cases, doctors may ask patients to fast for a few hours before the test, refraining from consuming anything except water. However, not all doctors may require fasting before testosterone testing. It is important to consult with your doctor to determine any necessary test preparations and follow their instructions diligently.
TESTP, TESTO, TESTB, TESTF, and SHBG blood tests are laboratory tests that measure different aspects of testosterone levels in the body. TESTP measures the total amount of testosterone in the bloodstream, while TESTO measures the free or unbound testosterone available by the body's cells. TESTB measures the amount of testosterone bound to a protein called sex hormone-binding globulin (SHBG), while TESTF measures the amount of free testosterone not bound to SHBG. SHBG blood test measures the levels of the protein that binds to testosterone in the bloodstream. These tests are important for diagnosing and monitoring hormonal imbalances related to testosterone, such as low testosterone levels, polycystic ovary syndrome (PCOS), or male hypogonadism. They can also help evaluate fertility issues and identify the cause of abnormal menstrual cycles in women.
TESTP, TESTO, TESTB, TESTF, and SHBG blood tests, collectively known as the testosterone panel, collectively known as the testosterone panel, can help in diagnosing and managing conditions related to hormonal imbalances by providing information about the levels of testosterone in the bloodstream. Low testosterone levels can cause symptoms such as decreased sex drive, erectile dysfunction, decreased muscle mass, and fatigue. On the other hand, high testosterone levels can cause symptoms such as acne, excessive hair growth, and menstrual irregularities in women. In the case of PCOS, women may have high levels of testosterone and other androgens, which can cause irregular menstrual cycles, excessive hair growth, and acne. Male hypogonadism is a condition in which the testes do not produce enough testosterone, which can cause delayed puberty, infertility, and decreased muscle mass. By utilizing the testosterone panel blood test, healthcare providers can accurately diagnose these conditions and effectively manage their treatment.

There may be specific preparations or guidelines to follow before undergoing tests such as total testosterone (TESTP), free testosterone (TESTO), bioavailable testosterone (TESTB), calculated free testosterone (TESTF), or sex hormone-binding globulin (SHBG) testosterone panel blood test. Your healthcare provider will give you instructions on preparing for the test, including fasting for a certain period, avoiding certain medications or supplements, or refraining from strenuous exercise before the test. It is important to follow these instructions carefully to ensure accurate test results. If you have any questions or concerns about the test, talk to your healthcare provider before the test.
Testosterone panel lab tests differ in how they measure testosterone levels in the bloodstream. TESTP measures the total amount of testosterone, while TESTO measures the free or unbound testosterone available by the body's cells. TESTB measures the amount of testosterone bound to a protein called sex hormone-binding globulin (SHBG), while TESTF measures the amount of free testosterone not bound to SHBG. SHBG blood test measures the levels of the protein that binds to testosterone in the bloodstream. Each test provides different information about testosterone levels and hormone balance, and your healthcare provider may order one or more of these tests based on your symptoms and medical history. For example, if you have symptoms of low testosterone levels, your healthcare provider may order a TESTP and a TESTO test to assess the total and free testosterone levels in your bloodstream. If you have symptoms of PCOS or male hypogonadism, your healthcare provider may also order an SHBG and a TESTB test to evaluate testosterone levels bound to SHBG. Each test provides valuable information for diagnosing and managing hormonal imbalances related to testosterone, and a combination of tests may be necessary for a more accurate assessment of hormone balance.
Certain medications, supplements, and lifestyle factors can influence the results of TESTP, TESTO, TESTB, TESTF, or SHBG blood tests. Medications such as steroids, hormonal therapies, and some antidepressants can affect testosterone levels and alter the test results. Herbal supplements, like saw palmetto or DHEA, may also impact hormone levels. It is crucial to inform your healthcare provider about any medications, supplements, or lifestyle factors that could influence the testosterone panel results. This information allows the healthcare provider to interpret the results accurately and make informed decisions regarding diagnosis, treatment, or further testing.
The time it takes to receive the results of TESTP, TESTO, TESTB, TESTF, or SHBG blood tests may vary depending on the laboratory and the healthcare provider. Typically, it takes a few days to receive the test results. Once you receive the results, your healthcare provider can interpret them and explain their meaning. The normal range for testosterone levels may vary depending on age, sex, and other factors. Your healthcare provider can help you interpret the test results based on your medical history and symptoms. Your healthcare provider may recommend further tests or treatment options if the test results indicate abnormal testosterone levels.
