Best Testosterone Blood Tests in the UK (2026): Medichecks vs Monitor My Health vs GP

Why Get a Testosterone Test?

A testosterone test makes sense if:

• You suspect low testosterone (fatigue, low libido, poor recovery, mood issues)
• You're tracking baseline hormone status before making nutritional or supplementation changes
• You want objective data on your hormonal status rather than relying on symptoms alone
• You're considering TRT and need baseline bloodwork

Symptoms of low testosterone (low T) include low energy, reduced libido, difficulty building muscle, poor recovery, and mood issues. But these are non-specific—they overlap with sleep deprivation, depression, and overtraining. Bloodwork is the only way to know for certain.

What Markers Actually Matter (The Full Panel)

A comprehensive testosterone assessment includes more than just total testosterone. Here's what to test and why:

Essential markers:

• Total testosterone: Combined free and bound testosterone. Normal range: 300-1000 ng/dL (10-35 nmol/L).
• Free testosterone: The biologically active form. Normal range: 50-210 pg/mL (175-730 pmol/L). This is more important than total T.
• SHBG (sex hormone-binding globulin): A protein that binds and inactivates testosterone. High SHBG = lower free testosterone. Normal: 10-100 nmol/L.
• LH (luteinizing hormone): Signals the testes to produce testosterone. Normal: 1.7-8.6 IU/L.
• FSH (follicle-stimulating hormone): Signals sperm production. Normal: 1.5-12.4 IU/L.
• Oestradiol: Testosterone converts to oestradiol via aromatase. High oestradiol contributes to symptoms (water retention, mood issues). Normal: 15-45 pg/mL.

Important supporting markers:

• Prolactin: High prolactin suppresses testosterone. Normal: <18 ng/mL.
• vitamin D (25-OH-D): Deficiency suppresses testosterone. Target: 75-150 nmol/L.

These are the markers that matter. A basic "total testosterone only" test (often what the NHS offers) is insufficient for diagnosis.

The Three Routes: GP vs Private Labs

Route 1: GP (NHS)

Pros:

• Free
• Legitimate diagnosis record (if you're hypogonadal, GP records it)

Cons:

• Tests only total testosterone (no free T, SHBG, oestradiol)
• Often dismissive of borderline results (symptoms aren't taken seriously unless total T is <200 ng/dL)
• Long waiting times (weeks to months)
• No vitamin D, prolactin, or supporting markers
• Your GP may not be experienced with hormonal assessment

Realistic scenario: You see your GP, they order total testosterone, results come back at 450 ng/dL (technically "normal" though suboptimal), GP says "you're fine," and you get no further support.

When to use: Only if you have severe symptoms and need NHS documentation. Otherwise, private labs are more thorough.

Route 2: Medichecks

What you get:

• Medichecks Male Hormones Advanced: Total T, Free T, SHBG, LH, FSH, Prolactin, Oestradiol, Vitamin D, TSH
• Home finger-prick collection (easier than phlebotomy) or walk-in to partner clinic (if you prefer venous blood)
• Results in 3-5 working days via secure online portal
• Clean, professional interface with clear normal ranges

Pros:

• Comprehensive panel (everything relevant)
• Home collection (convenient)
• Fast turnaround
• Can repeat testing easily for tracking
• Good value for the panel offered
• Results are private (not on NHS record, though you can share them with your GP)

Cons:

• Cost: ~£49-89 depending on which package (basic vs advanced)
• Finger-prick can yield small sample errors (though rare with Medichecks' established protocols)

Cost breakdown (2026 prices):

• Medichecks Male Hormones Basic (Total T, Free T, SHBG): ~£49
• Medichecks Male Hormones Advanced (above + LH, FSH, Prolactin, Oestradiol, Vitamin D, TSH): ~£79-89

The recommendation: Medichecks Male Hormones Advanced is the best value. You get everything relevant for ~£80.

Route 3: Monitor My Health

What you get:

• Similar hormone panels to Medichecks
• NHS-backed (results reviewed by NHS doctors)
• Home or walk-in collection

Pros:

• NHS backing provides credibility
• Good panel options
• Results reviewed by clinicians

Cons:

• Slightly more expensive than Medichecks (~£60-100)
• Slower turnaround (5-7 days typical)
• Fewer customisation options (less flexibility if you want additional markers)

My take: Monitor My Health is slightly more expensive and slower than Medichecks, with no clear advantage. Medichecks is better value.

Route 4: Thriva (Honourable Mention)

What you get:

• Hormone panels
• Home collection
• Fast turnaround

Cons:

• More expensive than Medichecks (typically £70-120)
• Fewer customisation options
• Not as comprehensive for comprehensive hormone panels

My take: Thriva is fine but more expensive than Medichecks for similar offerings. Medichecks remains better value.

My Recommendation for Most People

Best value: Medichecks Male Hormones Advanced, ~£79-89.

You get a comprehensive panel (everything relevant), quick turnaround (3-5 days), private and convenient (home finger-prick or walk-in), and excellent value.

If you want NHS involvement or prefer venous blood, Monitor My Health is reasonable (slightly more expensive, slightly slower, but NHS-backed).

Skip: Generic "total testosterone only" tests or the NHS route (unless you need NHS documentation for a clinical issue).

Practical Testing Protocol

1. Order test: Medichecks website, choose Male Hormones Advanced
2. Book collection: Home finger-prick (usually next day available) or walk-in to partner clinic
3. Fasting state: Not strictly necessary, but test in the morning if possible (testosterone is highest in early morning)
4. Lifestyle baseline: If you're testing for baseline purposes, test when your lifestyle is normal (not after a week of sleep deprivation or illness)
5. Wait for results: 3-5 days
6. Review: Read your results against normal ranges provided; assess free testosterone specifically (often more important than total T)

Understanding Your Results: The Key Markers

Total Testosterone: 300-1000 ng/dL (Normal Range)

• <300 ng/dL: Clinically low (hypogonadism). Consider investigation.
• 300-450 ng/dL: Low-normal. Symptoms possible. Consider dietary/supplementation fixes first (vitamin D, zinc, sleep).
• 450-700 ng/dL: Healthy range.
• 700-1000 ng/dL: High-normal/optimal.

• 1000 ng/dL: Supraphysiological. If not on TRT, investigate further.

Free Testosterone: 50-210 pg/mL (Normal Range)

This is arguably more important than total T. You can have normal total T but low free T if SHBG is elevated.

• <50 pg/mL: Low. Investigate cause (high SHBG, low total T, both).
• 50-100 pg/mL: Low-normal. May experience symptoms.
• 100-160 pg/mL: Healthy range.

• 160 pg/mL: Optimal.

SHBG: 10-100 nmol/L (Normal Range)

• Low SHBG: More free testosterone even if total T is modest. Often healthy (associated with good metabolic health).
• High SHBG: Binds testosterone, leaving less free. Can be caused by excessive alcohol, high oestrogen, liver disease, or simply genetics.

If your total T is 500 ng/dL but SHBG is 80 nmol/L, your free T may be suboptimal despite normal total T.

LH and FSH: Interpretation

• Low LH + low total T: Primary hypogonadism (testicles not responding) or secondary (pituitary not signalling). Requires investigation.
• Normal LH + low total T: Secondary hypogonadism (pituitary issue). Investigation needed.
• High LH + low total T: Primary hypogonadism (testicles failing). More difficult to treat naturally.

For baseline assessment, normal LH and FSH indicate your pituitary is functioning normally.

Oestradiol: 15-45 pg/mL (Normal Range)

• Low oestradiol: Rare in men. Can cause poor bone health.
• 15-45 pg/mL: Healthy range.

• 45 pg/mL: Elevated. May contribute to water retention, mood issues, gynecomastia risk. Often seen with high body fat.

Prolactin: <18 ng/mL (Normal Range)

• Elevated prolactin suppresses GnRH and LH, reducing testosterone. Worth checking. If elevated, investigate (pituitary prolactinoma, hypothyroidism, medications).

Vitamin D: 75-150 nmol/L (Optimal Range)

• <50 nmol/L: Deficient. Suppresses testosterone. Supplement immediately.
• 50-75 nmol/L: Insufficient. Consider supplementation.
• 75-150 nmol/L: Optimal for health and testosterone.

• 150 nmol/L: High (generally fine, but unnecessarily high).

Next Steps After Testing

If results are normal (all markers healthy):

• You're not hypogonadal. Symptoms are likely from other sources (sleep, stress, overtraining, poor nutrition).
• Focus on: consistent sleep (8+ hours), stress management, adequate training stimulus, protein intake, micronutrient status.

If free testosterone is low but total T is normal:

• High SHBG is the likely issue. Causes: excessive alcohol, high body fat, high oestrogen. Solutions: reduce alcohol, lose body fat, improve insulin sensitivity.
• Supplement with: vitamin D (if deficient), zinc (if deficient). Avoid supplements that boost oestrogen (like certain herbal adaptogens).

If total testosterone is low (<300 ng/dL):

• See an NHS endocrinologist or private clinic specialising in TRT. Low testosterone is treatable via TRT if warranted.
• Don't supplement your way out of clinical hypogonadism. You likely need pharmaceutical-grade testosterone.

If total testosterone is 300-450 ng/dL (low-normal) and you have symptoms:

• Optimise micronutrients first (vitamin D to 75-150 nmol/L, zinc to adequate intake, magnesium, omega-3).
• Optimise lifestyle (8+ hours sleep, strength training, stress management).
• Retest in 12 weeks. If still low and symptomatic, consider investigation or TRT.
