Testosterone blood test: How is testosterone measured in a blood test? Your testosterone levels fluctuate throughout the day, ranging from a few hundred to thousands of milligrams. Sometimes, they may rise because of a tumour in the ovary or adrenal gland. Other times, they may fall, due to a high level of prolactin. A blood test is helpful in diagnosing symptoms and helping your doctor determine the cause of any abnormalities.
Testosterone levels fluctuate throughout the day
During the morning, men have higher levels of testosterone than in the evening, which explains why the results of a testosterone blood test may be abnormal. Although the level of testosterone in a blood sample varies greatly between men, the average level is around 350. Some labs can report as high as 800. This is far higher than the normal level for an average male. The test will not detect a difference in a man’s sex drive due to a change in his testosterone level.
They can rise because of tumours in the ovary or adrenal gland
A high level of testosterone in a woman may be a sign of polycystic ovaries, which are a common hormonal imbalance. Women with these conditions may experience increased acne, body hair, and facial hair. In some cases, severe testosterone levels can also lead to infertility and obesity. Testosterone levels can also be raised in women with a group of inherited disorders called CAH, which affect the adrenal glands’ ability to produce estrogen and cortisol. In these patients, an enzyme that regulates hormone production is missing and the hormones produce too much testosterone. There are two types of CAH: nonclassic and classic, but the symptoms are not the same.
They can fall because of high levels of prolactin
If the test results reveal a significant drop in testosterone levels, it may indicate an underlying condition. Doctors measure hormone levels in nanograms per millilitre. Testosterone levels are measured by determining how much prolactin is present in the blood. The range is different for every person and lab. In some cases, high levels of prolactin can indicate a problem. Hyperprolactinemia occurs in a rare case, largely due to a malfunctioning pituitary gland.
They can help diagnose symptoms
If you think you might be experiencing the symptoms of low testosterone, a blood test for testosterone levels may be in order. While the total testosterone level is the most accurate way to diagnose low levels, it may not always be the best option. A low level of testosterone in a blood test could be a sign of a condition other than low levels of testosterone. If you suspect that you have low testosterone, it may be beneficial to undergo a blood test to determine whether your levels are normal or too high.
They can create a treatment plan
When it comes to men’s health, knowing how testosterone is measured in a blood test can help you create a treatment plan. Your doctor may want to know about your lifestyle or the cause of your declining levels. Often, medications and weight gain can cause your levels to decrease. There are many different ways to deliver testosterone replacement therapy to your body, including a skin patch. There are several other ways to measure testosterone in your blood, as well.
