A kidney function test is a set of blood and urine tests designed to assess the health and functionality of the kidneys. These tests typically include measuring serum creatinine, blood urea nitrogen (BUN), and glomerular filtration rate (GFR). They help diagnose and monitor conditions such as kidney disease, evaluate the kidneys’ ability to filter waste products from the blood, and assess electrolyte balance. Kidney function tests are crucial for detecting early signs of kidney dysfunction and guiding appropriate medical interventions. Professional interpretation of results is essential for accurate assessment and personalized healthcare management.
