However, when you’re undergoing TRT, some people test to determine the peak amount of testosterone, and some people try to grab the trough, says McDevitt. Clinically, if you’re doing well and your doctor agrees that your levels are within good ranges, then you’ll want to test every six months. During the ramp up, you should expect to test every 90 days until your levels get to a good therapeutic state, as determined by your doctor and how you feel. Our simple test gets mailed to your home and uses a few drops of blood to test for a wide range of biological markers, that are crucial to understanding your hormonal levels. Now, thanks to Hone’s at-home hormone test, testing your hormone levels has never been easier or more discreet. You used to have to go to the doctor’s office, or to a clinic that specializes in hormone evaluation.
Although this new information is somewhat reassuring, men and their doctors should still weigh these issues before committing to long term testosterone therapy. On treatment, the body stops making testosterone. If a man's testosterone is below the normal range, it's best to repeat it once more to be sure before starting testosterone therapy - often staying on it indefinitely. General fatigue and malaise has so many other causes, and when most men get a blood test, the result is a normal testosterone level. Women with high testosterone may reduce their testosterone levels naturally by incorporating certain foods and herbs into their diets. Medical conditions causing low levels of testosterone, such as ovarian tumors, should be treated by a medical professional. Many women suspect they have low testosterone or other androgen levels because they have low libido.
Beyond aggression, excessive testosterone can contribute to broader emotional instability, including anxiety, restlessness, and rapid mood swings that seem disconnected from external circumstances. Some men resist these interventions because they're focused on the benefits they feel from higher testosterone and don't want to dial it back. Others experience no symptoms at all until a serious cardiovascular event occurs.
In most cases, you should get the results of your testosterone test within two to three business days, though it could take longer. Your provider will let you know if you need to follow any specific instructions. High levels may point to precocious (early) puberty. Testosterone in your body exists in free (not attached to anything) and bound (attached to proteins) forms. Stay on top of latest health news from Harvard Medical School.

Just like it can be too low, your testosterone can also be too high, and that’s equally problematic (8). Accompanying the weight gain is muscle loss, and the inability to perform workouts to the same levels as before, but also seeing fewer results from the same workouts. "Honestly, a low libido is one of the least heard symptoms," McDevitt says. "What I’ve noticed in my patients," says McDevitt, "is that anyone in the 400s will start to exhibit symptoms of low T." In that case, your doctor may prescribe an aromatase inhibitor like anastrozole or TRT.
While levels below 300 ng/dL are considered clinically low total testosterone, McDevitt says that symptoms can appear even in a healthy range. Even if your total testosterone levels are in a normal range, your free testosterone can still be low. The average male who reaches 70 years old will have testosterone production that’s 30 percent below his peak (5). McDevitt says she sees older men who live a healthy lifestyle in their fifties who have the testosterone levels of a man in his thirties. You may talk to your healthcare provider about a testosterone level test if you have symptoms of low testosterone. Laboratories may have different reference ranges for normal testosterone levels.
Below is a chart representing the normal range for female testosterone levels by age and ng/dL. The most common "out of balance" testosterone levels are found to be on the low side of normal; this occurs because a male's highest testosterone level usually peaks at about age 20, and then it decreases slowly with age. But "normal ranges" for testosterone levels also vary based on the type of blood test done and the lab where it’s done.
