Fasting is generally not required for a testosterone blood test. However, there are a few things to keep in mind that can help ensure you get accurate test results:
- While fasting is not necessary, it is recommended to avoid high-fat meals before the test. Foods high in fats can temporarily increase testosterone levels and skew test results.
- Avoid alcohol consumption for at least 24 hours prior to the test as alcohol can also temporarily increase testosterone.
- Try to schedule your test for the morning when testosterone levels are naturally highest.
- Make sure you get adequate sleep the night before the test since lack of sleep may lower testosterone.
- Avoid intense exercise for 24 hours leading up to the test as heavy training can elevate testosterone.
- Certain medications and supplements may impact test results, so inform your doctor of everything you are taking. You may need to stop taking certain things temporarily.
Why Test Your Testosterone
- Low testosterone can negatively impact muscle mass, bone density, sex drive, energy levels, mood, cognitive function, and more. Getting tested is important for optimal health and wellbeing.
- Testing can help diagnose the cause of any symptoms you may be experiencing like fatigue, low libido, erectile dysfunction, and trouble building muscle.
- A test establishes your baseline levels so you can track changes over time.
- Testing enables your doctor to determine if testosterone therapy or other hormone treatments could benefit you.
When to Get Tested
Some good times to schedule a testosterone test include:
- If you have any symptoms of low T such as diminished sex drive, depression, fatigue, difficulty concentrating, erectile dysfunction, low muscle mass, weight gain, and hot flashes
- To establish baseline T levels if you are male over age 40
- To monitor T levels if you are undergoing testosterone replacement therapy
- If you have pituitary gland disorders or diseases affecting testicular function
- If you have chronic health conditions, as some like obesity and type 2 diabetes are associated with low testosterone
Understanding Your Test Results
Once you get your testosterone test results back, here are some key things your doctor will evaluate:
- Your total testosterone and/or free testosterone levels
- Your results compared to the lab's "normal" range
- Related hormone levels like estradiol, LH, FSH, etc.
- Trends in your testosterone levels over time
- Your symptoms and medical history in addition to lab results
There is no definitive threshold where "low T" is diagnosed based on lab results alone. Your doctor will take a holistic view of your health to determine if
hormone therapy or other treatments are recommended.
Reaching optimal testosterone levels takes some trial and error which is why ongoing partnership with an experienced
hormone clinic like Balance Hormone Clinic is so valuable. Their doctors specialize in testosterone replacement therapy and precision hormone treatments to help patients like you achieve peak vitality, health, and performance.
