Blood and urine tests that show how well your kidneys are filtering waste and balancing fluids and minerals.
Kidney function tests are a group of blood and urine tests that assess how effectively your kidneys remove waste from the body. Common markers include serum creatinine, blood urea, eGFR, electrolytes and protein in the urine.
These tests can detect kidney problems early, often before symptoms appear, and are also used to monitor people with conditions that put the kidneys at risk, such as diabetes and high blood pressure.
At Apollo Clinic Shyamnagar, kidney function testing is paired with a urologist consultation, so results are explained clearly and any follow-up tests such as ultrasound can be arranged promptly.
