Blood values and what they measure
Blood values are measurable substances in your blood. Together they sketch a picture of your energy, recovery and capacity. Look up a value and check its reference range. Each one explains what a high or low result says about your condition.

Selenium
Selenium is a key antioxidant that helps combat exercise-induced oxidative stress. It also supports thyroid function for optimal metabolic rate during training.
Serotonin
Serotonin is a neurotransmitter that may affect mood, motivation, and recovery. For active individuals and active individuals, balanced serotonin could support mental focus, quality sleep, and a positive mindset during training.
Sodium
Sodium is a critical electrolyte lost through sweat during training. Proper balance supports hydration, muscle contraction, and endurance performance.
TNF Alpha
TNF-α can indicate whether inflammation is related to training stress or systemic issues. Monitoring supports informed decisions about training load and recovery.
TPO Antibodies
TPO antibodies indicate potential autoimmune thyroid activity. For active individuals, undetected thyroid autoimmunity may subtly affect training capacity, recovery, and metabolic efficiency. Including TPO testing in your health monitoring can support optimal performance readiness.
TSH (Thyroid Stimulating Hormone)
Your TSH level shows how hard the pituitary is pulling on the thyroid. At the laboratory that runs the test the usual range runs from 0.27 to 4.20 mE/L. For anyone training hard, one reading is rarely the whole story. Sleep debt, a tight energy deficit and a heavy block all shift the axis temporarily. A high TSH points to an underactive thyroid. A low value fits an overactive one. What you want is the direction across several measurements. So give blood at roughly the same time each time.
TSH Receptor Antibodies
TRAb antibodies may indicate Graves' disease, which can cause hyperthyroidism. For active individuals, an uncontrolled overactive thyroid can significantly impact heart rate, recovery, and body composition. TRAb testing may help identify the cause of unexplained performance changes.
TSI (Thyroid Stimulating Immunoglobulin)
TSI antibodies may indicate Graves' disease, which can lead to hyperthyroidism. For active individuals, an overactive thyroid may affect metabolism, heart rate, and recovery. Understanding your TSI status can be part of a comprehensive approach to performance health.
Thyroglobulin
Thyroglobulin is a thyroid protein that may provide insight into thyroid gland function for active individuals. Some sports medicine providers note that thyroid health can influence metabolic rate, energy availability, and the body's response to training demands.
Thyroglobulin Antibodies
Thyroglobulin Antibodies are immune markers that may indicate autoimmune thyroid activity. For active individuals, undetected thyroid autoimmunity might subtly affect metabolic efficiency, recovery, and training adaptations over time.
Total Cholesterol
Total cholesterol is a starting point for lipid assessment. Active individuals should look at the full panel including HDL, LDL, and triglycerides for complete cardiovascular insight.
Total Protein
Total protein measures the combined amount of albumin and globulins in your blood. These proteins play essential roles in maintaining fluid balance, fighting infections, transporting substances, and supporting tissue repair.
Total T3 (Triiodothyronine)
Total T3 measures triiodothyronine, the most metabolically active thyroid hormone. For active individuals, T3 may influence metabolic rate, energy availability, and recovery capacity. Monitoring T3 can help you and your healthcare provider optimise your training readiness.
Total Testosterone
Total testosterone is a key hormone for physical performance, influencing muscle protein synthesis, recovery capacity, and energy output. For active individuals, monitoring testosterone may help optimize training adaptations and recovery strategies.
Transferrin
Transferrin is the delivery system for iron to working muscles. Monitoring it alongside ferritin and serum iron helps optimise oxygen transport for physical performance.
Transferrin Saturation
Transferrin saturation measures the percentage of iron-transport protein carrying iron, a critical marker for physical performance. Optimal iron status is essential for oxygen transport to working muscles, endurance capacity, and recovery from training.
Triglycerides
Triglycerides are used as fuel during exercise. Monitoring helps active individuals understand fat metabolism efficiency and metabolic health alongside performance.
Troponin T (Cardiac)
Troponin T can rise transiently after intense endurance exercise. Active individuals should be aware of this marker to distinguish training effects from cardiac concerns.
Urea (BUN)
BUN is a kidney function marker that active individuals should monitor regularly. Intense exercise, high-protein diets, and protein supplementation can all elevate BUN levels. Adequate hydration during training is essential for accurate results and optimal kidney function.
Uric Acid
Intense exercise can temporarily elevate uric acid. Monitoring helps active individuals distinguish training-related changes from metabolic concerns like gout risk.
Urine Bilirubin
Bilirubin is a yellow pigment formed when red blood cells break down. It is normally not found in urine, so a positive dipstick result can point to the liver or bile ducts.
Urine Blood
This dipstick result detects blood in the urine that may not be visible to the eye. Blood can come from anywhere in the urinary tract and has many possible causes, from infection to kidney stones.
Urine Culture
A urine culture supports active individuals in maintaining urinary health. Dehydration during intense training can increase UTI susceptibility, and certain supplements may alter urinary pH. Culture testing ensures accurate diagnosis when symptoms arise.
Urine Glucose
Glucose is normally reabsorbed by the kidneys and is not present in urine. When blood sugar is high, glucose can spill into the urine and show up on a dipstick test.
