How to Get Tested - NHS vs Private Options
Last updated: April 2026
If you're experiencing symptoms of low testosterone - fatigue, low libido, brain fog, reduced muscle mass - the first step is getting your levels checked. But navigating blood tests in the UK isn't straightforward.
This guide covers everything: NHS routes, private testing, what markers to check, and where to get the best value. If you prefer a phlebotomist at the kitchen table to a clinic visit, my Lola Health review covers the at-home nurse service in detail.

Why Test Your Testosterone?
Testosterone isn't just about sex drive. It affects:
- Energy levels - Persistent fatigue despite adequate sleep
- Muscle maintenance - Harder to build or keep muscle
- Mental clarity - Brain fog, poor concentration
- Mood - Irritability, low motivation, depression
- Metabolic health - Body fat distribution, insulin sensitivity
The problem: GPs often dismiss borderline results. "You're in range" doesn't mean optimal.
Testing tells you where you stand. Without a baseline, everything else is guesswork. Get a full panel - total T, free T, SHBG, LH, FSH and oestradiol - not just total testosterone. The NHS only offers the minimum. Private testing gives you the full picture for under £150.
For the trade-off between going through your GP and ordering a home kit, my piece on home blood test vs GP for UK men compares both routes head to head.
NHS Testosterone Testing
What's Available Free
The NHS will test total testosterone if you have symptoms. The process:
- Book GP appointment - Describe symptoms clearly
- Blood test - Usually morning (8-11am) when testosterone peaks
- Results - Typically 3-5 days
NHS reference range: 8-29 nmol/L (varies by lab)
NHS Limitations
| Issue | Why It Matters |
|---|---|
| Only total testosterone | Misses free testosterone (the active portion) |
| No SHBG testing | Can't calculate free testosterone |
| Single sample | Testosterone fluctuates; one test may miss patterns |
| "In range" dismissal | 10 nmol/L is "normal" but most men feel rubbish |
| Long waits | 2-3 week GP appointments in some areas |

Reality check: The NHS does the minimum. If you're borderline, you won't get the full picture.
The NHS tests total testosterone - nothing else. That's one data point out of five you need. If you have symptoms, go private for the full panel. The cost difference (free vs £80-150) is small compared to making health decisions based on incomplete data.
Private Testosterone Testing
Private testing solves the NHS limitations. Here's what you get:
Basic Testosterone Check (~£70-100)
Includes:
- Total testosterone
- Free testosterone (calculated)
- SHBG (sex hormone binding globulin)
- Albumin
Why it matters: SHBG binds testosterone. High SHBG = less free testosterone = more symptoms even if total looks "normal."
Comprehensive Male Hormone Panel (~£150-200)
Adds:
- Estradiol (oestrogen - aromatisation check)
- Prolactin (pituitary function)
- LH and FSH (hypothalamic-pituitary-gonadal axis)
- DHEA-S (adrenal androgens)
- Cortisol (stress indicator)
- Thyroid panel (TSH, T3, T4)
- PSA (prostate health if over 40)
When to get this: If you've had borderline NHS results or want a complete pre-TRT baseline.

Understanding Your Results
Total Testosterone
| Level | Interpretation |
|---|---|
| under 8 nmol/L | Deficient - likely symptomatic |
| 8-12 nmol/L | Low - probably symptomatic |
| 12-18 nmol/L | Low-normal - may have symptoms |
| 18-29 nmol/L | Normal - less likely symptomatic |
| > 29 nmol/L | High - investigate causes |

Free Testosterone
More important than total. Calculate using:
- Total testosterone
- SHBG
- Albumin
Optimal free testosterone: ~0.3-0.5 nmol/L (varies by age)
SHBG
Normal range: 18-54 nmol/L
High SHBG (binds more testosterone, less free):
- Liver disease
- Hyperthyroidism
- Alcohol abuse
- Aging
Low SHBG:
- Hypothyroidism
- Obesity
- Diabetes
- Steroid use
Estradiol
Optimal for men: 75-150 pmol/L
High estradiol symptoms: water retention, gynaecomastia, mood swings, low libido
Low estradiol: joint pain, low libido, brain fog
Next Steps After Testing
If Results Are Low
- Retest in 3 months - Confirm pattern (testosterone fluctuates)
- Lifestyle optimisation - Sleep, exercise, diet, stress (see our protocol)
- Consider TRT consultation - If lifestyle doesn't help and symptoms persist
Before Considering TRT
Get comprehensive testing:
- Full hormone panel
- PSA (if >40)
- Lipids
- Blood count
- Liver/kidney function

FAQ
Can I get testosterone tested on the NHS? Yes, but typically only total testosterone and only if you have clear symptoms. NHS won't test SHBG, free testosterone, or other hormones without exceptional circumstances.
How often should I test?
- Baseline: Once
- TRT patients: Every 3-6 months
- Optimising naturally: Every 6-12 months
What's the best time of day to test? Morning (8-11am). Testosterone peaks early and declines throughout the day.
Does ejaculation affect testosterone levels? Short-term studies show minimal effect on blood levels. Don't worry about this.
Should I fast before testing? Yes, 8-12 hours fasting gives most consistent results. Water is fine.
Summary
Best option for most men: Private basic test (£79) through Medichecks
Why:
- Tests SHBG and free testosterone (NHS doesn't)
- 24-48 hour results
- Home testing option
- Doctor commentary included
- Same NHS-accredited labs
Skip NHS unless you're pursuing TRT through them - the information is too limited.
