Are There Symptoms That Indicate the Need for a Kidney Function Test (KFT Test)?

Symptoms indicating the need for a KFT test include swelling in the legs or face, reduced or foamy urine output, persistent fatigue, high blood pressure, and unexplained weight changes. Other warning signs include nausea, itchy skin, and blood in the urine. Individuals with risk factors like diabetes, hypertension, or a family history of kidney disease should undergo KFT testing even without symptoms to detect issues early and ensure timely management.
