Blood values for strength athletes
Blood values show your condition from the inside, past anything the mirror tells you. Training hard shifts some values for a while, muscle and liver markers among them. Look up a value and read its reference range. You also see when a result genuinely needs attention.

Urine Bilirubin
Bilirubin is a bile pigment formed during the breakdown of red blood cells; the liver converts it into a water-soluble form, conjugated bilirubin, which normally leaves the body through the bowel and the stool.
Urine Blood
This dipstick result detects blood in the urine that may not be visible to the eye.
Urine Culture
A urine culture helps identify bacteria causing urinary tract infections in men.
Urine Glucose
Glucose is normally reabsorbed by the kidneys and is not present in urine.
Urine Ketones
Ketones are produced when the body breaks down fat for energy instead of glucose.
Urine Leukocytes
Leukocytes in the urine are white blood cells, cells of the immune system that protects the body against foreign invaders.
Urine Nitrite
Nitrite is not normally found in urine. Certain bacteria convert nitrate into nitrite, so a positive dipstick result can be a sign of a bacterial urinary tract infection.
Urine Screening
Urine screening provides men with a quick overview of kidney and metabolic health.
Urine Sediment
Urine sediment analysis provides men with detailed insight into kidney and urinary tract health.
Urine Sediment Leukocytes
Sediment leukocytes are white blood cells counted under the microscope in spun-down urine. A few are normal; a higher number can point to inflammation or infection in the urinary tract.
Urine Specific Gravity
Specific gravity reflects how concentrated your urine is, which is closely tied to how well hydrated you are. It typically ranges from about 1.002 to 1.035.
Urine Squamous Epithelial Cells
A 2005 US review describes squamous epithelial cells as large and irregularly shaped, with a small nucleus; a 2020 US study assumes they reach a urine sample from the genital surfaces.
Urine pH
Urine is more or less acidic, and that acidity is expressed as the pH; according to MedlinePlus, acids are removed from the blood by the kidneys.
Vitamin A
Vitamin A measures retinol levels, a fat-soluble vitamin important for men's health.
Vitamin B1 (Thiamine)
Vitamin B1 (thiamine) is considered essential for energy metabolism, which may support physical performance in men. Some men may notice fatigue or reduced endurance when levels are suboptimal.
Vitamin B12
Vitamin B12 is considered vital for red blood cell production, nerve health, and energy metabolism in men. Low levels may contribute to fatigue and reduced performance.
Vitamin B2 (Riboflavin)
Vitamin B2 (riboflavin) is considered important for energy metabolism and antioxidant protection in men. It may support cellular energy production during physical activity.
Vitamin B3 (Niacin)
Vitamin B3 (niacin) is considered important for NAD+ production, which may support energy metabolism and cellular repair in men. Adequate levels may contribute to cardiovascular and metabolic health.
Vitamin B6
Vitamin B6 is considered important for amino acid metabolism and neurotransmitter production in men. It may support muscle protein synthesis and testosterone metabolism.
Vitamin B7 (Biotin)
Vitamin B7 (biotin) is considered important for men's hair health, skin integrity, and macronutrient metabolism. Some men may notice changes in hair or nail quality when levels are low.
Vitamin C
Vitamin C is a powerful antioxidant considered important for men's immune function, collagen production, and iron absorption. It may support tissue repair after physical activity.
Vitamin D (25-OH)
Your vitamin D level shows how much vitamin D you have in store, and in the Netherlands that mostly reflects the sun of the past few months.
Vitamin E
Vitamin E protects cells from oxidative stress, supporting muscle recovery and cardiovascular health. It is an important antioxidant for active men.
Vitamin K1
Vitamin K1 is vital for blood clotting and bone integrity. Keeping levels in check supports recovery from injury and long-term skeletal strength.
