If you know your Total Testosterone, Albumin, and Sex Hormone Binding Globin (SHBG), you can calculate your Free Testosterone level.
Introduction to the Free Testosterone Calculator
Testosterone is a crucial hormone present in both males and females, though it is produced in higher quantities in males. It plays a significant role in maintaining bone density, muscle strength and mass, fat distribution, facial and body hair, red blood cell production, sex drive, and sperm production. While total testosterone measures the overall amount of this hormone in the body, free testosterone is what’s biologically active and available for the body to use. It is called ‘free’ because it isn’t bound to sex hormone-binding globulin (SHBG) or albumin, which are proteins that carry hormones in the blood. As such, the level of free testosterone can provide a more precise indicator of potential hormonal imbalances that might not be evident when measuring total testosterone alone.
Our Free Testosterone Calculator is a user-friendly tool that enables you to determine your free testosterone level based on your total testosterone, albumin, and SHBG levels. It is important to understand the role of free testosterone as it directly affects the body’s ability to perform its normal functions. For instance, low levels of free testosterone may lead to conditions such as fatigue, decreased sex drive, irritability, and depression in both men and women. In men, it might also lead to erectile dysfunction, decreased muscle and bone mass, and even infertility. On the other hand, excessively high levels can result in aggression, mood swings, acne, and an increased risk of heart disease and cancer.
Free testosterone levels can vary depending on various factors, including age, overall health, and time of day when the blood sample is taken. As a general reference, normal ranges for free testosterone are usually between 5.0 to 21.0 pg/mL (picograms per milliliter) for men and between 0.1 to 1.1 pg/mL for women. However, these ranges may differ slightly based on the laboratory and methods used for testing. Therefore, it is recommended to consult with a healthcare professional for a more accurate understanding of your results. Use this tool as a starting point to help you better understand your hormonal health, and always seek professional advice when in doubt.
