Why does testosterone have to be checked in the morning?

You may be asked to take a fasting test first thing in the morning. In that case, you should stop eating before midnight and then drink only sips of water in the morning. You can usually keep taking whatever medications you need, but check with your doctor. If you think you have low testosterone levels, check out these testosterone tests that you can order online at an affordable price and check how your hormones are doing.

Women produce much lower amounts of testosterone in the ovaries, adrenal glands, and other body tissues. The results of the above studies pave the way for a potentially important change in the way testosterone tests are done. The study revealed that testosterone levels decreased by approximately 25% after glucose ingestion. However, some studies suggest that fasting before a testosterone test can significantly alter final results.

A testosterone test is a test that measures the amount of testosterone in a person's blood or saliva. Many factors can affect the results of testosterone blood tests, including your age, health, and what's happening to your body. Testosterone levels vary widely depending on time of day, diet, age, fitness level, and other factors. Because the natural daytime variation in testosterone levels tends to decrease with age, it's acceptable to test men age 45 or older before 2 p.m.

There are different forms of testosterone in the blood that can be measured to help diagnose certain health problems. A testosterone level test alone cannot diagnose any health condition, but abnormal results with symptoms may be a sign of a health problem. The guidelines recommend collecting a sample first thing in the morning to compensate for the natural daytime variation in testosterone levels. Scientists have reason to believe that fasting is also important when it comes to controlling testosterone levels.

This study also exemplifies how testing testosterone levels while fasting is very different from testing them in a state of eating. The study measured total testosterone and did not take into account possible confounding factors, such as obesity or the use of testosterone replacement therapy or androgen deprivation therapy, which could affect globulin that binds to sex hormones and therefore could alter the total level of testosterone.
