Overview

Assess your hormonal vitality with our comprehensive Testosterone Blood Test. Whether you're experiencing low energy, reduced muscle mass, or changes in libido, this test measures your total testosterone levels to help identify hormonal imbalances affecting your overall well-being and quality of life.

Testosterone is often called the 'king of hormones' because it acts like your body's personal motivational speaker and performance enhancer all in one. This powerful hormone drives energy, builds muscle, sharpens mental focus, and fuels sexual desire in both men and women. While men produce it primarily in the testicles and women in smaller amounts through the ovaries and adrenal glands, testosterone plays crucial roles for everyone—from maintaining bone strength and muscle mass to supporting mood and cognitive function.

Here's the challenge: testosterone naturally declines as we age, typically dropping 1-2% each year after 30, but factors like stress, poor sleep, weight gain, and certain health conditions can cause levels to plummet even faster. When testosterone runs low, you might notice fatigue creeping in, difficulty building muscle, increased body fat, reduced motivation, or a declining interest in activities you once enjoyed. Our testosterone test helps you understand whether hormonal imbalances might be behind changes in your physical performance, mental clarity, or overall vitality, giving you the insights needed to take targeted action and reclaim your energy.

How to prepare

Morning collection (7-10 AM) essential as testosterone levels peak in early morning and decline throughout day. No fasting required. Avoid intense exercise for 24 hours before testing. Inform healthcare provider about medications, supplements, or recent illness that might affect hormone levels. Consider timing relative to menstrual cycle for women.

Understanding results

Men: Normal ranges vary by age - 20-30 years: 15-25 nmol/L; 40-50 years: 12-20 nmol/L; >60 years: 9-15 nmol/L. Women: 0.7-2.8 nmol/L throughout cycle. Low levels may indicate hypogonadism, aging, or other hormonal issues. High levels might suggest PCOS in women or other endocrine disorders. Results interpreted with symptoms and clinical context.

After the test

If low, consult healthcare provider specializing in hormone health for comprehensive evaluation. Consider lifestyle interventions including strength training, adequate sleep, stress management, and nutrition optimisation. Hormone replacement therapy may be appropriate for a significant deficiency. Address underlying causes such as obesity, sleep disorders, or medications affecting testosterone production.

Frequently Asked Questions

  • Total testosterone measures all testosterone in blood, while free testosterone measures only the unbound, biologically active portion. Both provide valuable but different information about hormone status.
  • Testosterone levels follow a circadian rhythm, peaking in the morning and declining throughout the day. Morning testing captures peak levels for accurate assessment.
  • Absolutely. Women produce testosterone too, and deficiency can cause fatigue, low libido, muscle weakness, and mood changes. Testing helps identify hormone-related symptoms in women.
  • Levels can fluctuate due to stress, illness, exercise, and other factors. Consistently low levels across multiple tests are more significant than single low results.
  • Sleep quality, exercise (especially strength training), body weight, stress levels, alcohol consumption, and diet all significantly influence testosterone production.
  • Baseline testing around age 30-35 is reasonable, with regular monitoring if symptoms develop. Earlier testing may be appropriate for specific symptoms or risk factors.

Having seen the GP regularly, I thought I had everything covered. I had no idea I had Type II diabetes as I was symptomless. Now I can manage it before it gets really bad. I never would have caught it this early if I hadn't used Bloody Good.
