Checking kidney health is crucial for early detection of potential issues, and there are several professional tests that can provide valuable insights. Key tests include the serum creatinine test, which measures kidney function by assessing creatinine levels in the blood; the glomerular filtration rate (GFR), which estimates how well your kidneys filter waste; the urine albumin test, which detects protein in the urine, an early sign of kidney damage; the urine test for microalbumin, indicating early kidney disease; and an ultrasound or imaging test, which helps visualize kidney size and structure. These tests, when performed regularly, can help detect kidney problems early, ensuring timely intervention and effective treatment to maintain kidney health.
