Kidney
23 markers in this category
Albumin-to-Creatinine Ratio (ACR)
Hard training can push albumin into your urine temporarily, with nothing wrong with your kidneys at all.
Citrate
Urinary citrate is essential for kidney stone prevention in active individuals.
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.
Microalbumin (Urine)
Microalbumin testing helps active individuals understand kidney stress related to intense training.
Oxalate
Urinary oxalate testing is important for active individuals who consume high-protein diets, protein supplements, or large quantities of oxalate-rich foods.
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.
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.
Urine Bilirubin
Bilirubin is a yellow pigment formed when red blood cells break down.
Urine Blood
This dipstick result detects blood in the urine that may not be visible to the eye.
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.
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, also called white blood cells, are immune cells that help protect 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 helps active individuals monitor hydration status, detect exercise-induced changes in kidney function, and identify potential issues from supplement use.
Urine Sediment
Urine sediment analysis helps active individuals understand the impact of intense training on 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
Squamous epithelial cells line the lower urinary and genital tract.
Urine pH
Urine pH describes how acidic or alkaline your urine is. It naturally varies through the day with diet, hydration and other factors, and usually falls between roughly 4.5 and 8.0.
eGFR (Estimated Glomerular Filtration Rate)
Your eGFR value tells you how many millilitres of blood your kidneys filter clean per minute, and in anyone who trains seriously that number regularly reads too low with nothing wrong with the kidneys. eGFR stands for estimated glomerular filtration rate: it is not a measurement but a calculation from your creatinine, your age and your sex.
