Kidney function tests are laboratory analyses that help assess how well the kidneys filter the blood and regulate body salts and fluids.
Read moreKidney function tests include measuring various substances in the blood to evaluate how effectively the kidneys perform their essential roles. These tests assess creatinine and urea nitrogen to determine how well waste products are eliminated, and measure electrolytes such as sodium, potassium, chloride, phosphorus, total calcium, corrected calcium, along with albumin and uric acid to understand mineral and fluid balance in the body. Albumin reflects the kidney’s ability to retain proteins, while uric acid provides information on metabolic waste buildup. These findings are used to diagnose kidney impairment, monitor chronic disease, assess dehydration, identify electrolyte disorders, and evaluate medication effects on kidney function.
