Testosterone is the primary sex hormone in men and a critical regulator of energy, muscle, mood, and fertility in both sexes. Low testosterone causes symptoms that are frequently misattributed to stress, age, or lifestyle — yet are directly correctable once identified. A single morning blood test provides the answer.

About the Test

Total and Free Testosterone

Testosterone circulates in two forms: bound (attached to proteins, inactive) and free (unbound, biologically active). Most labs only measure total testosterone — but free testosterone is the functional form. Both values together give the most complete picture of hormonal status.

🩸

Total Testosterone

Measures all testosterone in the blood — both protein-bound and free. Normal adult male range: 300–1,000 ng/dL. Normal female range: 15–70 ng/dL. Low total T is the primary diagnostic criterion for hypogonadism in men.

⚗️

Free Testosterone

The biologically active fraction (roughly 1–3% of total T). Some men have normal total T but low free T because high SHBG (sex-hormone binding globulin) binds excess hormone, causing symptomatic testosterone deficiency despite "normal" total T.

🌅

Why Morning Sampling Matters

Testosterone peaks between 7–10am and declines by 30–50% through the day. An afternoon sample in a man with borderline testosterone can appear normal when he is clinically deficient. Morning testing before 10am is essential for accurate diagnosis.

When to Test

Five Reasons to Test Testosterone

Low Libido, Erectile Dysfunction, or Reduced Orgasm

Testosterone drives sexual desire in both sexes. Low T is a correctable organic cause of reduced libido and ED — often missed when patients are prescribed sildenafil without testing hormone levels. A testosterone test identifies whether the cause is hormonal.

Unexplained Fatigue, Low Mood, or Poor Concentration

Low testosterone causes chronic fatigue, brain fog, low motivation, and depressed mood that does not respond well to antidepressants. If fatigue persists despite adequate sleep and thyroid is normal, testosterone is the next priority to check.

Loss of Muscle Mass or Increased Body Fat

Testosterone maintains muscle protein synthesis and inhibits fat accumulation. Men losing muscle despite exercise, or gaining abdominal fat without dietary change, often have low T. Correction reverses both processes.

Female Infertility or PCOS

Elevated testosterone in women with irregular periods, excess facial hair, acne, or difficulty conceiving indicates PCOS or adrenal pathology. Testosterone is part of the PCOS hormonal screen alongside LH, FSH, and prolactin.

Male Infertility Investigation

Low testosterone impairs sperm production. Combined with LH and FSH, a testosterone result distinguishes primary testicular failure from secondary (pituitary) hypogonadism — which determines whether treatment is possible or referral needed.

Testosterone Reference Ranges

Male normal

300–1,000 ng/dL

Male borderline

200–300 ng/dL

Female normal

15–70 ng/dL

PCOS elevated (female)

>70 ng/dL

⚕️ Context matters: symptoms + hormone levels together guide treatment decisions. A testosterone of 280 ng/dL in a symptomatic man with low free T may warrant treatment even if total T is near the lower normal limit.

Preparation

How to Prepare for Your Testosterone Test

Timing and preparation dramatically affect testosterone results — follow these steps for a clinically meaningful result.

🌅

Come Before 10am — Morning Sample Essential

Testosterone follows a circadian rhythm, peaking at 8am and falling 30–50% by afternoon. Schedule your blood draw before 10am for a valid result. An afternoon result in a man with borderline T can create a false-normal reading.

🍽️

8-Hour Fast Preferred

Fasting is not mandatory for testosterone, but an 8-hour fast improves accuracy for any concurrent glucose or lipid testing. If you are only testing testosterone, water is fine. Come having slept well — poor sleep the night before measurably suppresses morning T levels.

💊

Disclose All Medications & Steroids

Anabolic steroids suppress endogenous testosterone and LH/FSH. Opioids, corticosteroids, and some antifungals lower testosterone. High-dose biotin interferes with immunoassay-based testosterone tests. Tell us everything you take — including supplements.

Trusted Hormone Testing in Akoka & Beyond

🌅

Morning Appointments for Accurate Results

We understand that morning sampling is essential for testosterone. We prioritise early slots and our team knows to collect testosterone samples before 10am — not just at any convenient time.

⚗️

Total and Free T Available

We offer both total and free testosterone measurement. Free testosterone catches cases where total T appears normal but symptomatic deficiency is present due to elevated SHBG — a missed diagnosis elsewhere.

📋

Full Hormone Context Available

Testosterone doesn't exist in isolation. We can extend your panel to include LH, FSH, prolactin, and SHBG — giving your doctor the full pituitary-gonadal axis picture needed for treatment decisions.

🔒

Discreet & Confidential

Testosterone and sexual health concerns are sensitive. Our team treats every patient with professional discretion. Results are delivered to you personally — never shared without your consent.

"I was 38, always exhausted, no sex drive, couldn't build muscle despite training. My GP said it was stress. Mascot Healthcare did total and free testosterone — free T was critically low even though total was 'borderline normal'. That result changed everything. Treatment made a complete difference."
