Performance Blood Test Packages Explained
A detailed breakdown of what's tested in each Performance tier, and why every marker earns its place.
Built around training and recovery
Most blood tests are designed to detect disease. Our Performance panels focus on training and recovery. The laboratory's reference ranges are based on healthy people in general, so context such as heavy training matters when you read a result.
Each Performance tier builds on the last, adding more markers at each level. You can start with a baseline or choose a higher tier for more markers.

Performance Bronze: The Essential Foundation
The Bronze panel covers core markers often checked by people who train regularly. Think of it as a baseline to build on.
Full Blood Count gives you a broad view of red and white blood cell health, identifying anaemia, infection risk, and oxygen-carrying capacity. Kidney Function checks how well your kidneys are filtering, and results can be affected by high muscle mass. Creatine Kinase reflects muscle damage, so it can add context when you review training load.
Vitamin D supports bone health and immune function, and has been linked with testosterone and mood. Ferritin reveals your iron stores. Depleted stores are one of the most common causes of unexplained fatigue in athletes, especially women. Vitamin B12 and Folate are critical for red blood cell production and energy metabolism.
This panel answers the fundamental question: are your foundations solid enough to build performance on?
Performance Silver: A Closer Look
Silver adds hormonal, metabolic, and inflammatory markers often reviewed when training feels harder than it should.
Cortisol (AM) and Total Testosterone are commonly looked at together when assessing training load. The ratio alone cannot diagnose overtraining, but it can add context to how you feel.
Thyroid Function governs your metabolic rate, energy levels, and body composition. Even subclinical thyroid dysfunction has been linked with reduced exercise tolerance in some studies. Lipid Profile provides cardiovascular context, critical for endurance athletes and anyone monitoring heart health alongside performance.
hs-CRP is a highly sensitive inflammation marker that flags systemic stress from overtraining, poor recovery, or underlying issues. Magnesium and Zinc complete the panel: two minerals that can be depleted by intense exercise. Magnesium is involved in muscle function and has been linked with sleep quality, and zinc helps maintain normal testosterone levels.
Silver adds context on how your body is handling training.
Performance Gold: In Depth
Gold is the most detailed panel in our Performance range. It includes everything in Silver, plus markers covering hormones, blood sugar, iron and cardiovascular health.
Homocysteine is an independent cardiovascular risk marker that also reflects B-vitamin metabolism. Elevated levels have been linked with cognitive decline. SHBG (Sex Hormone-Binding Globulin) provides useful context for testosterone results, because it affects how much is biologically available.
HbA1c gives you an average of your blood sugar over the past two to three months, rather than the single moment a glucose reading shows. Insulin complements HbA1c by revealing how hard your pancreas is working to maintain that control, catching metabolic dysfunction years before it shows on standard tests.
Omega-6:Omega-3 Ratio is tested less often. It reflects the balance of these fats in your diet, which has been linked with inflammation, recovery and brain health.
Free Testosterone (calculated from Total Testosterone and SHBG) tells you what's actually available to drive muscle protein synthesis, recovery, and mental sharpness. Iron Profile replaces the single ferritin test with a fuller view of iron transport and storage, which is useful if ferritin appears normal but performance is still suffering.
Gold doesn't just test more markers. It adds markers that give more context to your metabolic and hormonal results.
Why the Combination Matters
Each tier isn't just "more tests". It's a carefully designed combination where markers inform and contextualise each other.
Ferritin without a Full Blood Count can mislead. Testosterone is often read alongside cortisol when looking at training load, and insulin adds context to HbA1c. Our panels are built so that every marker adds context to the others.
This is the difference between a list of numbers and results you can understand. If you choose an optional AI summary, it explains how your results relate to each other in plain English.
