Nyrerefunksjonstest

Nyrerefunksjonstest, often translated as kidney function test, refers to a series of medical evaluations used to assess how well the kidneys are performing their vital tasks. These tests help detect kidney disease, monitor its progression, and evaluate the effectiveness of treatments. The kidneys are responsible for filtering waste products and excess fluid from the blood, regulating blood pressure, producing hormones, and maintaining electrolyte balance. When kidney function declines, these processes are impaired, leading to various health issues.

Common kidney function tests include blood tests and urine tests. Blood tests, such as serum creatinine and blood urea nitrogen (BUN), measure the levels of waste products in the blood that the kidneys are supposed to remove. Elevated levels can indicate reduced kidney filtration. Another crucial blood test is estimated glomerular filtration rate (eGFR), which estimates how much blood the kidneys filter per minute. Urine tests, like urinalysis, can detect the presence of protein, blood, or other abnormalities in the urine, which are signs of kidney damage. A 24-hour urine collection may also be performed to precisely measure how much protein or other substances are being excreted. These tests are essential tools for healthcare professionals in diagnosing and managing kidney-related conditions.
