Understanding Testosterone
What is Testosterone?
Testosterone is a vital sex hormone produced primarily in the testicles in men and in smaller amounts in the ovaries in women. It plays a crucial role in the development of male reproductive tissues and promotes secondary sexual characteristics such as muscle mass, bone density, and hair growth. In women, testosterone helps maintain hormone balance and regulates various bodily functions. This hormone is essential for overall health, influencing everything from physical strength to mood and energy levels.
Normal Testosterone Levels
Normal testosterone levels vary depending on age, sex, and other factors. In adult men, typical testosterone levels range from 300 to 1,000 ng/dL, while in adult women, levels typically fall between 15 and 70 ng/dL. It’s important to note that testosterone levels naturally decline with age. Abnormal testosterone levels, whether too high or too low, can indicate underlying health issues that may require medical attention. Monitoring these levels can provide valuable insights into your health and help identify potential problems early on.
What is a Testosterone Test?
A testosterone test is a medical test that measures the amount of testosterone in your body. In women, testosterone tests can also help diagnose conditions like polycystic ovary syndrome, which is characterized by hormonal imbalances. It is done through a blood or saliva sample and can help determine if your testosterone levels are within a normal range. Testosterone tests can measure both total testosterone (all testosterone in the blood) and free testosterone (the testosterone not bound to proteins like SHBG). These tests are useful in diagnosing symptoms like low energy, decreased muscle mass, and changes in mood or sex drive.
- Blood Draw or Saliva Test? Testosterone levels can be measured with either a blood draw or saliva test, but blood tests are typically more accurate. Expect a visit to your doctor or a clinic, where a quick blood draw will provide the necessary sample.
- Total vs. Free Testosterone: The test will often include measurements for both total testosterone (bound to proteins) and free testosterone (available for use by your body).
Signs You Might Need a Testosterone Test: Symptoms of Low Testosterone
If you’re experiencing these symptoms of low testosterone, it’s time to consider a testosterone test. Here are some of the most common indicators that your testosterone might be low:
- Fatigue: Constant tiredness, even after a good night’s sleep.
- Low Libido: A reduced interest in sex can be a strong indicator of low testosterone.
- Mood Changes: Anxiety, irritability, and even depression could be linked to decreased testosterone levels.
- Loss of Muscle Mass: Struggling to keep or gain muscle despite exercise.
- Weight Gain: Particularly around the abdomen, even with diet control.

Types of Testosterone Tests
There are several types of testosterone tests, each measuring different aspects of testosterone levels, providing a comprehensive picture of your hormonal health. The most common types are:
| Test Type | Description | Purpose/Importance |
|---|---|---|
| Total Testosterone Test | Measures the total amount of testosterone in the blood, including testosterone bound to proteins such as SHBG and albumin. | Provides an overall view of testosterone levels, as about 98% is bound to proteins and not immediately available for use. |
| Free Testosterone Test | Measures the testosterone that is not bound to any proteins and is available for use by the body. | Shows the active testosterone that tissues are using, useful for understanding symptoms like low libido or decreased energy. |
| Bioavailable Testosterone Test | Measures both free testosterone and testosterone loosely bound to albumin, which is available for biological activity. | Provides a more precise indication of how much testosterone is actively being utilized by the body. |
| Saliva Tests | A non-invasive way to measure testosterone levels, often used in research settings or for convenience. | Less accurate than blood tests, but offers a convenient alternative. |
| SHBG Test | Measures SHBG levels, which can help interpret total testosterone results, especially when free testosterone levels don’t align with symptoms. | SHBG affects the availability of testosterone and can fluctuate due to age, obesity, or thyroid conditions. |
Each type of test provides a different piece of the puzzle, which is why healthcare providers often recommend a combination of these tests to get a comprehensive understanding of your hormonal health. By analyzing both total and free testosterone, along with bioavailable testosterone, you can get a more accurate diagnosis of conditions like hypogonadism or other hormone imbalances.
The type of testosterone test you need depends on your symptoms and what your doctor wants to investigate. A complete panel can give the clearest insight into your health.
Preparing for a Testosterone Test
Preparing for a testosterone test is crucial to ensure accurate results. Since testosterone levels fluctuate throughout the day, it’s recommended to schedule your test early in the morning when levels are at their peak. Avoid strenuous exercise and heavy meals before the test, as these can affect your testosterone levels. Inform your healthcare provider about any medications or supplements you are taking, as some can influence hormone levels. By following these steps, you can help ensure that your test results provide a true reflection of your testosterone levels, allowing for accurate diagnosis and effective treatment planning.
How the Testosterone Test Works: The Role of a Blood Sample
A testosterone levels test is straightforward and efficient. Here’s a breakdown of what to expect:
- Book an Appointment: Visit your healthcare provider or book a telehealth consult to start the process.
- Prepare for the Test: Testosterone levels vary throughout the day—they peak in the morning. For accurate results, schedule the test early in the morning.
- The Blood Draw: Your healthcare provider will collect a small sample of blood, typically from a vein in your arm. The process takes just a few minutes.
- Review Results with Your Doctor: Your doctor will help you interpret the results, discussing the optimal ranges and any potential next steps if levels are low.
What Happens After the Testosterone Test?
Understanding Your Test Results & Typical Ranges
| Test Type | Normal Range | What Results Mean |
|---|---|---|
| Total Testosterone (ng/dL) | Men: 300 – 1,000 ng/dL Women: 15 – 70 ng/dL | Low Total Testosterone: May indicate hypogonadism, fatigue, low libido, or other health issues. High Total Testosterone: May suggest hormonal imbalances or tumors. |
| Free Testosterone (pg/mL) | Men: 9 – 30 pg/mL Women: 0.3 – 1.9 pg/mL | Low Free Testosterone: Can lead to symptoms like low energy, reduced muscle mass, or decreased sexual function. High Free Testosterone: Can indicate hyperandrogenism. |
