GFR Test: A Simple Blood Check for Kidney Health
A GFR test, introduced in the 1920s-1930s, is a simple blood test that assesses kidney function. It's often ordered if you have symptoms like swelling, foamy urine, or a history of conditions like diabetes or hypertension. The test is straightforward, with minimal side effects, and results are calculated using various factors including age, sex, and blood test results.
GFR results determine the stage of kidney damage, ranging from minimal (stage 1) to severe (stage 4). Doctors use these results to recommend appropriate treatment. Certain medications can affect creatinine levels, which are also measured during the GFR test. The test doesn't require any preparation and typically causes no major side effects, though some may experience throbbing or bruising at the puncture site.
GFR tests are crucial for understanding and managing kidney health. They help diagnose kidney disease, assess damage, and guide treatment. If you have symptoms or risk factors, consult your doctor about getting a GFR test.
