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.

Parathyroid Hormone (intact)
Parathyroid hormone is central to calcium regulation, which directly impacts bone integrity, muscle contraction, and recovery in active individuals. Monitoring PTH helps ensure your mineral metabolism supports peak physical performance.
Phosphorus
Phosphorus is essential for ATP production — the primary energy currency during exercise. Monitoring supports optimal energy availability for training and competition.
Platelets (Thrombocytes)
Your platelet count appears on every complete blood count. It reports the platelets in your blood in ×10⁹/l.
Potassium
Potassium is lost through sweat and is critical for muscle contraction and heart function during exercise. Monitoring helps prevent cramping and maintain performance.
Pregnenolone
Pregnenolone is the starting point for all steroid hormone production, including those critical for recovery, stress management, and performance.
Progesterone
Your progesterone value tells you whether you ovulated in this cycle, and for an athlete it is the first blood value to give away that the energy balance has become too tight.
Prolactin
Prolactin influences reproductive hormone balance and recovery capacity. For active individuals, monitoring prolactin can help identify hormonal disruptions that may affect training outcomes, sleep quality, and overall performance.
Protein (Urine)
Proteinuria testing helps active individuals distinguish between exercise-induced proteinuria, which is temporary and generally benign, and persistent proteinuria that may indicate kidney stress.
RDW
RDW shows how much your red blood cells vary in size. For active people this is valuable, because healthy red blood cells carry oxygen to your muscles.
Reticulocytes
Reticulocytes reveal how rapidly your body is producing fresh red blood cells — a key recovery metric for active individuals.
Reverse T3
Reverse T3 is an inactive thyroid hormone that may increase during overtraining, underfuelling, or physical stress.
SAA (Serum Amyloid A)
SAA responds rapidly to inflammation and can help distinguish training-induced inflammation from infection. This supports smarter recovery decisions for active individuals.
SHBG (Sex Hormone Binding Globulin)
Your SHBG value tells you how much of your testosterone circulates bound, and so is unavailable to your muscles and bones.
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.
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.
TSH (Thyroid Stimulating Hormone)
Your TSH value tells you how hard your pituitary is pulling on your thyroid, and in anyone who trains hard that number moves with sleep, energy balance and load.
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.
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.
Thyroglobulin
Thyroglobulin is a thyroid protein that may provide insight into thyroid gland function for active individuals.
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.
