Testosterone Test
A testosterone test is a simple blood test used to measure how much testosterone is circulating in your body. This hormone plays a vital role in many functions (across all genders and age groups), including muscle mass, mood, energy, fertility, and sexual health. Too much or too little testosterone can signal an underlying imbalance that may be affecting your wellbeing, often without obvious signs.
At Evergreen Doctors, we use testosterone testing as part of a broader, root-cause approach to health. Whether you're experiencing fatigue, changes in mood, difficulty building muscle, irregular periods, or other hormone-related symptoms, a testosterone level test can help clarify what’s going on and guide your next steps.
What is a Testosterone Blood Test?
A testosterone blood test measures the levels of testosterone in your bloodstream. Testosterone is produced primarily by the testicles in men and by the ovaries and adrenal glands in women. It exists in two forms: free (available for your body to use) and bound (attached to proteins like SHBG).
There are two main types of testosterone lab tests:
- Total testosterone test: Measures both free and bound testosterone combined.
- Free testosterone test: Measures only the active, usable hormone.
Depending on your symptoms and history, we may recommend one or both as part of your overall hormone evaluation.
Testosterone Testing: When Should You Consider It?
Your practitioner might suggest testosterone testing if you’re experiencing symptoms such as:
In men
- Low libido or erectile issues
- Muscle loss or low stamina
- Infertility
- Fatigue or brain fog
- Mood changes or low motivation
In women
- Acne or excess facial/body hair
- Irregular menstrual cycles
- Hair thinning
- Unexplained weight gain
- Difficulty conceiving
We may also recommend testing testosterone levels during a broader hormonal assessment that includes a TSH blood test, ferritin blood test, or HbA1c blood test, depending on your symptoms.
What to Expect During a Testosterone Lab Test
A testosterone blood test is quick and minimally invasive. A small sample of blood is usually taken from a vein in your arm, ideally in the morning when testosterone levels are at their highest.
Your results are typically ready within 1 to 2 business days. Usually, no extensive preparation is required, though fasting might be advised in some cases. Our team will guide you if any additional steps are needed.
At Evergreen Doctors, we combine your testosterone test with a thorough clinical discussion and, when appropriate, complementary tests such as a C-Reactive protein test, ApoB blood test, or full body scan for cancer to build a complete picture of your health.
What Testing Your Testosterone Levels Might Tell Us
Normal testosterone levels vary depending on your sex, age, and health status. We review your results in context, not just against a general lab range.
Low testosterone in men can be related to:
- Primary or secondary hypogonadism
- Pituitary gland issues
- Nutrient deficiencies or chronic illness
High testosterone in women can be linked to:
- Polycystic ovarian syndrome (PCOS)
- Adrenal disorders
- Hormone-secreting tumours
- Certain medications or supplements
If your levels are outside the expected range, we’ll work with you, and your specialist, to identify contributing factors such as diet, stress, medications, inflammation, or environmental exposures.
A Functional Medicine Approach to Testosterone Testing
Unlike traditional care, which may focus only on bringing levels into range, Evergreen Doctors takes a broader view. We explore the “why” behind your results and how your hormones interact with other systems like metabolism, thyroid health, and nutrient status.
That’s why a testosterone lab test is often included alongside other key tests, such as a haemoglobin blood test or an on-demand blood testing panel to help you understand how all systems are working together.
Your personalised plan may include lifestyle changes, targeted nutrients, or referrals to an endocrinologist, , all supported by evidence-based guidance.
Take the First Step Toward Better Hormonal Health
If you’ve been experiencing symptoms you can’t explain, or just want to understand your body more clearly, a testosterone blood test is a simple but powerful starting point.
