Best Blood Test for Biohacking (UK)

If you track your sleep, monitor heart rate variability, count macros or experiment with fasting, you already know what your habits feel like. A biohacking blood test tells you what they are actually doing to your body. This guide explains the biomarkers worth tracking and which Chxhealth panels go deep enough to be useful.

What separates a biohacking panel from a standard health screen?

Standard health screens cover the basics: liver, kidney, lipids, glucose. They are designed to catch disease, not optimise wellbeing.

Biohacking panels add depth: detailed hormone profile, insulin sensitivity markers, inflammation markers, micronutrient status (iron, vitamin D, B12, folate, sometimes magnesium and zinc), recovery and stress markers (cortisol, CRP), and the full thyroid picture.

If you are already tracking sleep, training, diet and supplementation, a deeper biomarker baseline is the missing piece that ties subjective tracking to objective data.

Biomarkers worth tracking longitudinally

Metabolic: Fasting glucose, HbA1c, fasting insulin, lipid profile.

Hormones: Testosterone, SHBG, oestradiol (for women), thyroid (TSH, free T4, free T3), cortisol.

Inflammation and recovery: Hs-CRP, full blood count, ferritin.

Liver and kidney: ALT, AST, GGT, creatinine, eGFR.

Nutrient status: Vitamin D, vitamin B12, folate.

Testing cadence

Annually is the bare minimum for baseline tracking. Every 3 to 6 months is common for active biohackers experimenting with interventions (diet, fasting protocols, supplementation, training blocks).

Test under standardised conditions: same time of day, same fasting status, same training recovery, no recent illness. Consistency makes the comparison meaningful.

FAQs

How often should a biohacker test?

Annually as a minimum. Every 3 to 6 months is typical for active experimenters. Quarterly testing is the upper end and most useful when you are running a specific intervention with a clear start and end date.

Should I test before or after my morning workout?

Always before. Strenuous exercise transiently affects multiple markers (liver enzymes, inflammation, hormones). Skip training for 24 to 48 hours before testing for a clean baseline.

Are Chxhealth ranges different from clinical ranges?

Chxhealth uses standard UK clinical lab reference ranges from our lab partner Randox. The biomarker glossary explains the nuance between standard NHS-aligned ranges and optimal ranges sometimes cited by clinicians or researchers.

Can the panel diagnose anything?

No. Chxhealth is a biomarker and genetic data provider. We do not diagnose, treat or prescribe. Our service supports your wellbeing journey alongside your healthcare professional.
