If fertilization does not occur, the corpus luteum degenerates, leading to a decrease in hormone levels and subsequent menstruation, initiating a new cycle5. In some cases, healthcare professionals may request multiple tests over a certain period of time to get a more accurate picture of your testosterone levels. This can help identify any long-term trends or fluctuations that may occur. In addition to these alternative tests, there are also newer and more specialized tests that can be used to check testosterone levels. One example is the dried blood spot test, which involves collecting a small amount of blood on a filter paper and measuring testosterone levels from this sample. This test is particularly useful for individuals who have difficulty providing a traditional blood sample, such as children or individuals with a fear of needles. Like the name suggests, this test involves collecting urine over a 24-hour period and measuring the amount of testosterone present in the urine.

One improvement I would make to the tests is clearer marking on the boxes and inserts stating which test you’re taking. If you order multiple tests, it can be unclear which test you’re taking until you activate it — or you have to search through the codes on the biohazard bags and test tube to work it out. It may be a really good fit for people who need results quickly and those who aren’t used to taking finger-prick tests. The ordering and testing process is very easy and relatively pain-free, and results come quickly.

Hypogonadism is categorized as either being primary or secondary.

However, it is worth noting that high testosterone levels are rare in cases where someone is not taking testosterone. If your results show high testosterone levels, it might be worth meeting with your doctor to confirm the results through a physician-ordered blood test and to discuss your next steps. For males under age 45 years, a testosterone test is usually performed in the morning when T levels are highest. Sometimes, the test needs to be retaken to confirm the measurements. Only a testosterone test can measure how much of the hormone is in your body and determine whether your level is within a healthy range. An abnormal testosterone test result doesn’t guarantee that you have a medical condition. Other factors, like certain medications and existing health conditions, can affect your test results.

In men, artificially high testosterone can lead to testicle shrinking, low sperm count, infertility, heart damage, and a higher risk of a heart attack. Disorders of the pituitary gland, adrenal gland, or ovaries may also play a role in testosterone imbalance. Testosterone tests evaluate testosterone in the saliva, blood, or urine.

The test measures the amount of testosterone in the blood and provides a numerical value that indicates the level of the hormone. A 2016 study in the Journal of Sexual Medicine found that the variability of testosterone test results can be as high as 40% when levels are below 100 ng/dL. And that’s a problem because even subtle differences in hormone levels can indicate a health concern, particularly in females. While older at-home tests measured only total testosterone, newer-generation blood and saliva tests can also measure free and bioavailable testosterone.

Your lab report should show the range that your lab uses for each test. Your doctor will also look at your results based on your age, health, and other factors.

Testosterone testing is part of the work-up of certain adrenal tumors. Seeing an abnormal test result may kick off alarm bells in your mind. But know that having an abnormal testosterone result doesn’t necessarily mean you have a serious medical condition. Your healthcare provider will let you know if you need further tests. Your child’s healthcare provider may recommend a testosterone blood test if your child has signs of starting puberty earlier or later than expected. Some of the participants stated that they had growth of hair on the back due to increased testosterone levels after exercise. When getting tested for testosterone levels, it is important to follow certain guidelines to ensure accurate results.

Additionally, the levels of testosterone in saliva and urine can be influenced by other factors such as oral medication, diet, and stress, further impacting the accuracy of these tests. While it’s the most widely used test, caution is needed when interpreting the results. First, a lot of the testosterone bound to proteins is not active in the body. Also, the percentage that binds to proteins differs; it differs from one man to the next. Laboratories set normal values based on men having their blood drawn between 7 a.m.
