What is the blood test for testosterone?
The blood test for testosterone, often referred to as the testosterone blood test, is a diagnostic health test used to measure the levels of testosterone in a person's bloodstream. Testosterone is a hormone produced primarily in the testicles for men and the ovaries for women and is essential for numerous bodily functions, including sexual development, muscle mass, and bone density. The testosterone blood test is typically conducted using a finger prick capillary sample or blood draw, according to Dr. Michael S. Irwig, an endocrinologist and expert on testosterone. The testosterone hormone levels in the blood sample are then analysed in a laboratory, and the results are able to provide valuable information about an individual's hormonal health.

What are the signs of low testosterone?
Low testosterone, known as hypogonadism manifests in various ways, such as loss of muscle mass, reduced sex drive and mood swings. Common symptoms of low testosterone include reduced sex drive, erectile dysfunction, fatigue, depression, and difficulty concentrating. Physically, individuals with low testosterone experience loss of muscle mass, increased body fat, and reduced bone density, according to Dr. Robert S. Tan, a specialist in andropause and male aging. Low testosterone results in sleep disturbances, such as insomnia or sleep apnoea. It is important to note that these symptoms are able to be attributed to other factors, so it is crucial to consult a medical professional for proper diagnosis and treatment or text a testosterone home test to be sure.
When should testosterone levels be checked?
Testosterone levels must be checked when a patient is exhibiting and experiencing symptoms of low testosterone. Determining the time to check testosterone levels depends on various factors, including age, symptoms, and overall health. As testosterone levels naturally decrease with age, particularly after the age of 30, it is essential to monitor these levels regularly. Men experiencing symptoms of low testosterone or other hormonal imbalances are able to have their levels checked, according to Dr. Ronald S. Swerdloff, an endocrinologist and expert in testosterone deficiency. Additionally, men with a family history of low testosterone or certain medical conditions, such as type 2 diabetes or obesity, should consider having their testosterone levels evaluated.

Testosterone blood test results explained
Testosterone blood test results are typically reported in units of nanograms per decilitre (ng/dL) or nanomoles per litre (nmol/L). Dr. Adrian Dobs, an endocrinologist and testosterone expert, explains that the normal range for total testosterone levels varies depending on age, sex, and individual factors.
For adult men, the normal range is generally between 300-1,000 ng/dL (10-35 nmol/L), while for women, it is usually between 15-70 ng/dL (0.5-2.4 nmol/L).
Results falling outside the normal range indicate low or high testosterone levels, associated with various health issues.
Can I use this test if I am taking testosterone replacement therapy (TRT)?
Yes, you can use the testosterone blood test while undergoing testosterone replacement therapy (TRT). Monitoring testosterone levels through blood tests is an essential component of managing TRT to ensure appropriate dosing and treatment effectiveness, according to Dr. Richard Bebb, an expert in testosterone and TRT. In addition, it is crucial to inform your healthcare provider about your TRT to ensure an accurate interpretation of the test results and any necessary adjustments to your treatment plan.
When is the best time to take the Testosterone Blood Test?
The best time to take the testosterone blood test is typically in the morning, as testosterone levels are generally highest during the early hours of the day.

However, if you are undergoing TRT or have a specific medical condition, your healthcare provider recommends a different time for the test.
Can women take this test?
Yes, women can take the testosterone blood test, as testosterone plays a crucial role in women's health, including bone density, muscle mass, and sexual function.
Does this test measure high levels of testosterone?
The Welzo testosterone blood test measures low and high testosterone levels. High testosterone levels, although less common, associated with various health issues, such as polycystic ovary syndrome (PCOS) in women or testosterone-producing tumours in men. Therefore, if your test results indicate high testosterone levels, it is essential to consult a healthcare professional to determine the underlying cause and develop an appropriate treatment plan.
What causes low testosterone levels in men?
Various factors, including age, lifestyle, and medical conditions cause low testosterone levels in men. Natural age-related decline in testosterone production is a common cause of low levels, according to Dr. Peter J. Snyder, a specialist in testosterone and male reproductive health. In addition, certain lifestyle factors, such as obesity, lack of exercise, excessive alcohol consumption, and poor sleep, contribute to reduced testosterone levels. Medical conditions, such as hypogonadism, pituitary gland disorders, or testicular damage, result in low testosterone.
Can you increase your testosterone levels naturally?
Yes, there are several natural ways to boost testosterone levels. Adopting a healthy lifestyle, which includes regular exercise, a balanced diet, and maintaining an optimal weight, is essential, according to Dr. Andre Guay, a specialist in male hormones and sexual function. Resistance training, such as weightlifting, has promoted increased testosterone production. A protein-rich diet, healthy fats, and essential nutrients support hormonal balance. In addition, managing stress, getting sufficient sleep, and limiting alcohol consumption improve testosterone levels. It is crucial to consult a healthcare professional for personalised advice on increasing testosterone levels naturally.
Testosterone in Sports and exercise explained
Testosterone is critical in sports and exercise by promoting muscle growth, strength, and overall physical performance. Higher testosterone levels contribute to increased muscle mass, reduced body fat, and improved athletic performance. It is essential to maintain healthy testosterone levels within the normal range, as excessively high levels lead to health issues and be considered doping in professional sports.

What is a good testosterone level?
A good testosterone level varies depending on age, sex, and health. As previously mentioned, the normal range for total testosterone levels in adult men is generally between 300-1,000 ng/dL (10-35 nmol/L), while for women, it is typically between 15-70 ng/dL (0.5-2.4 nmol/L). It is important to note that optimal testosterone levels differ between individuals, and a healthcare professional provides personalised advice on what constitutes a good testosterone level for each person.
What can cause low testosterone levels?
Low testosterone levels result from various factors, including an age-related decline in hormone production, lifestyle factors, and medical conditions.
Will I be able to get treatment if I get tested?
If your testosterone test results indicate low or high levels, a healthcare professional is able to help determine the appropriate treatment options based on the underlying cause and individual factors.
