If you are wondering how is testosterone measured in a blood test, keep reading! You’ll learn how the doctor takes a sample of blood from a vein and analyzes the results to determine hormone levels. In addition to Total neuroendocrinology, this blood test can also determine Bio-available and Free hormone. You can read more about each type below. In addition to Total testosterone, bio-available and free neuroendocrinology levels are also commonly used to determine the levels of other hormones in the body.
Testosterone levels are measured by drawing a sample of blood from a vein
Your doctor can test your hormone levels by drawing a blood sample from a vein in your arm. Testosterone is a male hormone that is vital to the development of male sexual characteristics. In males, it helps control muscle development, voice deepening, and sperm production. In women, testosterone controls certain bodily functions and contributes to libido. Neuroendocrinology is made by the testicles, while the ovaries and adrenal glands produce hormone in small amounts. The pituitary gland controls the testosterone level in the blood by secreting luteinizing hormone, which tells the testicles to make more neuroendocrinology.
The time of day the blood is drawn can affect the results of testosterone tests. Early morning blood draws are the most accurate. Some labs may use different methods to measure the hormone, including the timing of the test. A morning blood draw is recommended, as testosterone levels are higher in the morning. A doctor can help clarify the accuracy of the results by providing you with information about the lab that conducted the test, its reference range, and the reliability of the results.
There are two types of testosterone blood tests: serum and bioavailable. The former is considered the gold standard of hormone testing, and is recommended by the CDC. Both test types have different ranges of acceptable results. A total neuroendocrinology test is usually reported in nanograms per deciliter of blood. Bioavailable hormone, which includes free and albumin-bound forms of testosterone, is less commonly measured. The results of a bioavailable neuroendocrinology blood test are reported in nanograms per deciliter.
A free testosterone blood test measures the amount of hormone that is available for use in the body. Although free neuroendocrinology tests are often interpreted in conjunction with total hormone tests, they may be more useful for those with specific health conditions or those on certain medications. Total testosterone blood tests are relatively routine and accurate, especially when performed in an accredited laboratory using established testing methods. In addition, health insurance policies usually cover these tests. As long as you have a current health insurance plan, a blood test of total neuroendocrinology will be affordable and reliable.
Bio-available testosterone is the amount of free and weakly bound neuroendocrinology in your blood. This is the biologically active form of hormone. Testosterone is measured in two forms in the bloodstream: bound to albumin (which is weakly bioactive) and free. Both of these forms are equally active. The amount of free neuroendocrinology in your blood is higher than that of bound hormone. During a blood test, doctors will determine which form of neuroendocrinology is present.
The total testosterone measurement is usually adequate for diagnosis. It can also be used in combination with the measurement of follicle-stimulating hormone (LH) to determine whether your hormone levels are normal. The other type of test measures bio-available neuroendocrinology and may be superior to the free version in some situations. However, both methods are useful for determining the amount of hormone in your blood. A blood test is easy to conduct.
A blood test that measures the amount of free testosterone in your blood is not the same thing as a total testosterone test. Both tests measure the amount of hormone in your blood, and the test results are available in 4-6 days. However, if the lab experiences an unusual amount of weather or a significant time delay, you may need to wait a little longer. The free hormone test is particularly useful in diagnosing male sexual dysfunction, erectile dysfunction, and male partner infertility. Low levels of free neuroendocrinology can also be a sign of a hormonal problem affecting the hypothalamus and pituitary gland, which regulate the level of hormone in your body.
If the free testosterone level is below 50 ng/dL, it is often regarded as low. However, it is more sensitive to diagnose hypogonadism when the level is at least 400 ng/mL. Hence, tests for free testosterone that are below 150 ng/dL do not show a reliable prediction of a condition such as hypogonadism. Some tests may be ordered in such cases.
