Why Everyone in London is Getting Private Blood Tests (And What They're Finding Out)
Something interesting is happening in London's health scene. People aren't waiting until they're ill to investigate their health anymore. They're taking control, getting comprehensive blood tests, and discovering things their NHS GP never thought to check.
Maybe you're exhausted despite sleeping eight hours. Perhaps you're struggling to lose weight no matter what you try. Or you just have this nagging feeling that something's "off" but your GP says your basic blood tests are "normal."
Here's what those people discovered: "normal" doesn't mean optimal. The NHS tests for disease, not for thriving. And the difference between surviving and thriving often shows up in blood markers your standard NHS panel doesn't even check.
The NHS Reality Check
Your NHS GP is brilliant for many things, but they're working within constraints. When you say you're tired, they'll check your thyroid (TSH only), maybe iron, possibly B12. That's it. Budget constraints and guidelines mean they can't run comprehensive panels just because you "don't feel right."
Even when they find something, "normal range" is based on the general population – including ill people. If your testosterone is at the bottom of the normal range, you're told you're fine. Never mind that you feel terrible and your levels are appropriate for someone 30 years older.
Private blood testing isn't about replacing the NHS. It's about getting the complete picture when the system can't provide it.
What People Are Actually Testing For
Through The Wellness London, here's what people are discovering about their health:
The "Why Am I So Tired?" Panel: Beyond basic iron, we're checking ferritin (stored iron), full thyroid panel (TSH, T3, T4, antibodies), vitamin D, active B12, folate, and inflammatory markers. Amazing how many "exhausted" people have multiple deficiencies their GP never caught.
One patient, a 32-year-old lawyer, was told her tiredness was "just stress." Her private bloods showed Hashimoto's thyroiditis, vitamin D deficiency, and borderline B12. Three months of proper treatment and she felt like a different person.
The Hormone Deep Dive: For men: testosterone (total and free), SHBG, oestradiol, LH, FSH, prolactin. We're finding London men in their 30s with testosterone levels of 70-year-olds, explaining their fatigue, low libido, and difficulty building muscle.
For women: comprehensive hormone panel including day 3 and day 21 tests, AMH for fertility, and full thyroid workup. PCOS, perimenopause, and thyroid issues are chronically underdiagnosed.
The Metabolic MOT: HbA1c, fasting insulin (not just glucose), full lipid panel including ApoB and Lp(a), liver function, kidney function. We're catching pre-diabetes years before symptoms appear, when lifestyle changes can actually reverse it.
The Inflammation Investigation: CRP, ESR, homocysteine, and specific antibody tests. Chronic inflammation underlies everything from depression to heart disease, yet it's rarely checked comprehensively.
The Tests That Changed Everything
Vitamin D: The "normal" range starts at 50 nmol/L, but optimal is 75-150. Most Londoners are deficient, especially October through March. It affects everything: mood, immunity, bone health, muscle function, even weight loss.
Thyroid Antibodies: Your TSH can be "normal" while antibodies attack your thyroid. Catching Hashimoto's early means treatment before you're severely hypothyroid.
Insulin Resistance: Your glucose can be normal while insulin is sky-high, working overtime to keep blood sugar stable. This is reversible with diet changes if caught early.
B12 and Folate: "Normal" B12 starts at 200 pg/ml, but Japan treats anything under 500. Many people feel dramatically better with levels over 600.
Testosterone (for everyone): Yes, women need it too. Low testosterone in women causes fatigue, low libido, and difficulty maintaining muscle. In men, "normal" might be 8.64 nmol/L, but you felt great at 25.
Cortisol: Not just one reading, but a four-point saliva test throughout the day. Adrenal dysfunction is real and fixable, despite what some doctors say.
How Private Testing Actually Works
Option 1: Home Testing Kits Order online, kit arrives next day. Finger prick or self-collected samples. Post back, results in 24-48 hours. Perfect for basics, though some tests need venous blood.
Option 2: Clinic Visit Book online, visit our London clinic same day. Phlebotomist takes samples, full range of tests available. Results same day for basics, 24-48 hours for comprehensive panels.
Option 3: Mobile Phlebotomy We come to you – home, office, wherever. Small additional fee but maximum convenience. Popular with busy professionals and anxious patients.
All results are reviewed by a GP, not just automated. You get interpretation, not just numbers.
Understanding Your Results (The Part That Actually Matters)
Getting results is just the start. Most private testing fails here – they send you numbers without context. You need to understand:
Reference ranges vs optimal ranges: Being "in range" doesn't mean you're optimal. We look at where you should be for your age and circumstances.
Patterns matter more than individual markers: Low ferritin + high platelets might indicate bleeding. Low B12 + high MCV suggests absorption issues.
Trending is crucial: Your TSH going from 1.5 to 3.5 is significant, even though both are "normal."
Context is everything: A marathon runner's CK will be elevated. A nightshift worker's cortisol pattern will differ. Good interpretation considers your whole situation.
The Cost Breakdown That Makes Sense

Kidney and liver function
Cholesterol
Diabetes check
Comprehensive Wellness: £149-249
Everything above plus
Full thyroid panel
Vitamins and minerals
Inflammatory markers
Hormones (basic)

Compare this to going private for each issue separately – endocrinologist (£250), nutritionist (£150), multiple GP appointments (£150 each). Comprehensive testing is actually economical.
When to Test and How Often
Baseline Testing: Everyone should have comprehensive bloods by 30, earlier if symptoms exist. This becomes your reference point.
Symptomatic Testing: Unexplained fatigue, weight changes, mood issues, libido problems, hair loss – don't wait.
Monitoring: If you're optimising health, every 3-6 months initially, then annually once stable.
Specific Timing:
Hormones: Women need cycle-specific timing
Cortisol: Four-point test throughout the day
Fasting tests: 12 hours minimum
Testosterone: Morning for most accurate results
What Your Results Might Reveal
Real examples from our London patients (anonymised):
The 28-year-old with "anxiety" who had severe hyperthyroidism. Medication fixed both the thyroid and the anxiety.
The CrossFit enthusiast who couldn't lose weight despite intense training. Insulin resistance and cortisol dysfunction from overtraining. Protocol adjustment changed everything.
The executive with "normal aging" fatigue at 42. Testosterone of 6 nmol/L (normal starts at 8.64). TRT gave him his life back.
The woman told her hair loss was "genetic." Iron stores (ferritin) of 15 (optimal is 70+). Iron supplementation regrew her hair.
The vegan feeling great but wanted to check. Low B12, low iron, low vitamin D, borderline zinc. Targeted supplementation maintained the diet while fixing deficiencies.
Taking Action on Your Results
Getting results without action is expensive procrastination. Here's what happens next:
Deficiencies: Specific supplementation protocols, not random vitamins. Right forms, right doses, right timing.
Hormonal Issues: Options from lifestyle changes to bioidentical hormones to medical intervention. Always starting with the least invasive approach.
Metabolic Problems: Detailed nutrition and exercise plans based on your specific markers. What works for insulin resistance differs from thyroid issues.
Inflammation: Identifying and addressing root causes – gut health, hidden infections, food sensitivities, stress.
Optimisation: Fine-tuning levels for performance, not just avoiding disease. The difference between surviving and thriving.
The Hidden Benefits Nobody Mentions
Validation: Finally having proof you're not "making it up" or "just stressed."
Leverage: Concrete data to show your NHS GP when requesting treatment.
Prevention: Catching issues years before symptoms develop.
Optimisation: Understanding your body's unique needs, not generic advice.
Peace of mind: Either confirming health or catching issues early.
