Free Testosterone – what do your numbers mean?
Have you had your Free Testosterone level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what high or low levels can mean, and when it makes sense to get tested.
What is the normal range for Free Testosterone?
What is the normal range for Free Testosterone?
The normal range for free testosterone varies depending on age, sex, and laboratory method. In men, the normal range is typically between 0.2-0.6 nmol/L, while in women it is lower, often below 0.03 nmol/L. Levels can decrease with age, especially in men, where testosterone production gradually declines from the age of 30. Laboratories may use different methods, which can affect reference values. It is important to note that values close to the limits may indicate a need for further investigation, especially if there are accompanying symptoms such as fatigue or decreased libido.
What does a low level mean?
A low level of free testosterone can lead to symptoms such as decreased libido, fatigue, depression, loss of muscle mass, and increased fat mass. In men, the most common causes are primary hypogonadism, secondary hypogonadism, or chronic diseases such as diabetes and obesity. Women with low testosterone may experience reduced energy and sexual desire. Particularly vulnerable groups include older men and individuals with chronic diseases. If you experience symptoms, you should contact a doctor to have a blood test and possibly further investigations.
What does a high level mean?
A high level of free testosterone can lead to symptoms such as acne, increased body hair, aggressive behavior, and in women, a deeper voice and irregular menstruation. Common causes include polycystic ovary syndrome (PCOS) in women, testosterone-producing tumors, or the use of anabolic steroids. It is important to seek medical advice if you experience symptoms, as high levels can indicate underlying diseases. Treatment depends on the cause and may include medical intervention or lifestyle changes.
