SelectedThe Gold Athlete Performance profile is a comprehensive blood test designed for athletes, high performers, and physically active individuals who want to optimise training, recovery, and long-term health. It evaluates key systems that directly influence performance, including hormones, oxygen delivery, muscle recovery, metabolic efficiency, inflammation, and organ function.
This profile includes:
Hormones & Endocrine Health
Testosterone
Free Testosterone (calculated)
Sex Hormone Binding Globulin (SHBG)
Luteinizing Hormone (LH)
Follicle Stimulating Hormone (FSH)
Oestradiol (E2)
Thyroid Stimulating Hormone (TSH)
Free T4 (thyroxine)
Recovery, Muscle & Inflammation
Creatine Kinase
High Sensitivity C-Reactive Protein (hs-CRP)
Blood & Oxygen Transport
Haemoglobin
Haematocrit
Red Cell Count
Mean Cell Volume (MCV)
Mean Cell Haemoglobin (MCH)
Mean Cell Haemoglobin Concentration (MCHC)
Red Cell Distribution Width (RDW)
White Cell Count

This profile provides elite-level insight into training capacity, recovery efficiency, hormonal balance, and overall resilience.
Training hard without understanding your internal physiology can lead to underperformance, injury, burnout, or hormonal disruption. This profile identifies hidden bottlenecks that affect strength, endurance, recovery, and consistency.
It is particularly valuable for athletes training at high volume or intensity.
You may benefit from this test if you:
Train frequently or competitively
Experience plateaus despite consistent training
Feel fatigued or slow to recover
Want to optimise hormone balance naturally
Are cutting weight or body fat
Want to reduce injury or overtraining risk
Need data-driven performance optimisation
Want elite-level health and performance insight
Optimises hormone balance for performance
Testosterone, thyroid hormones, and SHBG support strength and energy.
Assesses recovery and muscle damage
Creatine kinase and inflammation markers guide training load.
Evaluates oxygen delivery capacity
Red blood cell and haemoglobin markers affect endurance.
Identifies iron-related fatigue risks
Full iron studies support aerobic performance.
Monitors cardiovascular health
Lipid profile and ratios support long-term heart health.
Screens metabolic efficiency
HbA1c reflects glucose control and energy utilisation.
Supports injury and overtraining prevention
Inflammation and stress markers highlight overload risk.
Provides elite, data-driven insight
Ideal for serious athletes and high performers.

Both services are available UK-wide.
Low iron, ferritin, vitamin D, B12, testosterone, or red blood cell indices may reduce endurance, recovery, and training output. Thyroid or hormonal suppression can further impair performance and body composition.
UK reference interpretation:
Low: Below laboratory reference ranges
Results within optimal ranges indicate good recovery capacity, efficient oxygen delivery, hormonal balance, and metabolic resilience. This supports sustained training and progression.
UK reference interpretation:
Optimal: Within laboratory reference ranges
High creatine kinase, hs-CRP, liver enzymes, or urate may indicate excessive training load, inflammation, dehydration, or insufficient recovery. Lipid or glucose abnormalities may affect long-term health.
UK reference interpretation:
High: Above laboratory reference ranges

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
