Testosterone Test: Free & SHBG, High vs Low vs. Normal Levels

Understanding total testosterone vs free testosterone

It is important to be aware of these symptoms in order to seek appropriate medical attention and treatment if necessary. On the other hand, levels of free testosterone that are above the normal range may indicate an excess of the hormone. This condition, known as hyperandrogenism, can lead to symptoms such as increased aggression, acne, excessive body hair growth, and an enlarged prostate. Hyperandrogenism can be caused by various factors, such as tumors in the testes or adrenal glands, certain medications, or genetic disorders.

Additionally, we could not use the serum estrogen level as a variable due to a lack of data. Therefore, we believe that our data provide the most concrete evidence among the studies that attempted to elucidate the relationship between testosterone levels and nephrolithiasis. In both men and women, persistently high levels of % Free Testosterone can lead to symptoms like acne, hair loss, increased body hair, mood swings, and even cardiovascular issues over time.

On the other hand, a woman with symptoms of excessive hair growth or acne may benefit from a lower level of free testosterone. During puberty, testosterone levels increase significantly, leading to the development of secondary sexual characteristics such as facial hair, deepening of the voice, and increased muscle mass. This surge in testosterone levels is essential for the physical and sexual maturation of males.

Monitoring % Free Testosterone is particularly important in diagnosing conditions like hypogonadism, polycystic ovary syndrome (PCOS), and certain metabolic disorders. It’s also used to track the effectiveness of hormone replacement therapies. Various factors can influence % Free Testosterone levels, including obesity, liver disease, thyroid disorders, and certain medications.

If you suspect you have high or low testosterone levels, it is recommended to consult with a healthcare professional for further evaluation and guidance. Sometimes, health care providers may also check only the total testosterone level and ignore the levels of free testosterone. If you experience low testosterone symptoms, then talk to your doctor about total and free testosterone tests to get his suggestions. Various medical conditions can lead to an imbalance in testosterone levels. Hypogonadism, a condition characterized by the body’s inability to produce enough testosterone, can be present from birth or develop later in life due to an injury or infection. Other conditions such as diabetes, thyroid disorders, and pituitary gland diseases can low testosterone cause low platelets also affect testosterone production. While total testosterone gives a broad overview of an individual’s testosterone status, free testosterone provides a more nuanced understanding of its biological activity in the body.

In conclusion, the normal range of free testosterone levels in men is between 9-30 ng/dL. This range indicates optimal hormone levels for maintaining muscle mass, bone density, energy levels, and reproductive health. Deviations from this range, either too low or too high, can indicate hormone imbalances or deficiencies that may require medical intervention and treatment. Regular monitoring and evaluation of testosterone levels, along with a comprehensive assessment of symptoms, can help ensure optimal health and well-being for men. This decline is normal but can sometimes lead to symptoms like decreased muscle mass, reduced energy levels, mood changes, and a lower sex drive. In women, testosterone levels are generally consistent but can be affected by factors like ovarian function and certain health conditions.

A healthcare professional can conduct appropriate testing, assess hormone levels, and provide guidance for tailored treatment or management options. Prioritizing our health and seeking medical attention when needed can help address any underlying hormonal imbalances and promote overall well-being. During adolescence, testosterone levels experience a significant increase, contributing to the development of secondary sexual characteristics and overall physical maturation. The study found that normal testosterone ranges during adolescence typically fall between 300 to 1,000 ng/dL. Factors such as diet, exercise, and sleep patterns can play a role in testosterone levels. Maintaining a healthy weight, engaging in regular physical activity, and adopting stress-reducing practices can support optimal testosterone production.

Simply attach an image or file of your lab test results, and a qualified team member from our data entry team will add the results for you. Labcorp OnDemand also offers a Men’s Health Test that checks total testosterone along with blood sugar, cholesterol and other key health indicators. Have an open discussion with your healthcare provider about whether testosterone testing may be right for you. That being said, it can be worthwhile to ask your doc to also get numbers for your free T, bioavailable T, and SHBG levels. These sub-numbers can help shed light on why you may be experiencing symptoms when everything looks normal with the total T. “We do sometimes initiate treatment on men with a low calculated free T if the total T is borderline,” Dr. Welliver says.
