Need to understand a Lasix renal scan? Focus on assessing glomerular filtration rate (GFR). This test measures how well your kidneys filter waste from your blood. A low GFR suggests kidney impairment.
The procedure involves an initial scan, followed by injection of Lasix (furosemide), a diuretic. A second scan is performed to evaluate kidney response to the medication. Expect to drink plenty of fluids before the scan and potentially experience temporary thirst.
Key things to remember: Results show how well your kidneys concentrate and excrete urine. Doctors use these results to diagnose various kidney conditions, including chronic kidney disease. Preparation involves fasting or limited food intake before the test; your doctor will provide precise instructions.
Important note: This information is for general understanding and does not replace medical advice. Consult your healthcare provider for personalized recommendations and to discuss any concerns you may have before and after the procedure.
