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.

Borrelia IgG (Lyme Disease)
A Borrelia IgG test detects IgG antibodies against Borrelia burgdorferi, the bacterium that causes Lyme disease.
Borrelia IgM (Lyme Disease)
A Borrelia IgM test detects IgM antibodies against Borrelia burgdorferi, the bacterium responsible for Lyme disease.
C-Peptide
C-Peptide provides insight into insulin dynamics, which affects energy availability, fat metabolism, and recovery. Active individuals benefit from understanding their metabolic efficiency.
CA 15-3
CA 15-3 is a glycoprotein marker that, when included in a broader panel, provides a more complete baseline for performance-focused individuals.
CA 19-9
CA 19-9 is a gastrointestinal marker that contributes to a thorough baseline for performance-focused individuals.
CA 72-4
CA 72-4 is a gastric and ovarian tissue marker that contributes to a thorough baseline health profile for performance-focused individuals.
CA-125
A CA-125 blood test measures the level of cancer antigen 125 in your blood.
CEA (Carcinoembryonic Antigen)
CEA is a broad tumor marker that, when included in a comprehensive health panel, contributes to a thorough baseline profile for performance-focused individuals.
CK-MB
CK-MB helps distinguish heart-related enzyme elevations from skeletal muscle damage during intense training. It supports cardiovascular safety monitoring for active individuals.
CRP (C-Reactive Protein)
Your CRP value tells you how large an inflammatory response is running in your body right now.
Calcitonin
Calcitonin is a thyroid-produced hormone that regulates calcium and bone metabolism.
Calcium
Your calcium blood level tells you how much calcium circulates in your blood, 2.18 to 2.55 mmol/l in adults.
Ceruloplasmin
Ceruloplasmin plays a role in iron metabolism and antioxidant defence, both important for physical performance and recovery from training stress.
Chloride
Chloride is lost through sweat during intense exercise. Monitoring your levels helps ensure proper electrolyte replenishment and supports optimal training performance.
Cholesterol/HDL Ratio
The cholesterol/HDL ratio is your total cholesterol divided by your HDL. Exercise tends to raise HDL, which lowers the ratio.
Citrate
Urinary citrate is essential for kidney stone prevention in active individuals.
Complete Blood Count (CBC)
A complete blood count tells you in one panel how many red blood cells, white blood cells and platelets your blood holds and how much haemoglobin you have, and for an athlete it is mainly a trend instrument.
Coombs Test (Indirect)
The indirect Coombs test screens for unexpected antibodies in your blood that may react against red blood cells. It is an important test for transfusion safety and prenatal care.
Copper
Copper is involved in energy production and iron transport — both critical for physical endurance and performance. Monitoring supports optimal training outcomes.
Cortisol
Cortisol reflects your body's recovery and stress load. For active individuals, monitoring cortisol helps identify overtraining, optimise recovery windows, and balance training intensity with adequate rest.
Creatine Kinase (CK)
Creatine kinase (CK) is an enzyme found primarily in the heart, brain, and skeletal muscles.
Creatinine
Your creatinine level is a measure of how well your kidneys filter the blood.
Creatinine (Urine)
Urinary creatinine is particularly relevant for active individuals, as intense exercise, high muscle mass, and protein supplementation can all influence excretion levels.
Cystatin C
Cystatin C is the preferred kidney function marker for active individuals because it is not affected by muscle mass, exercise intensity, or protein supplementation.
