What Are the Symptoms of Abnormal Kidney Function Found in a KFT Test?

Symptoms of abnormal kidney function may include fatigue, swelling (edema) in the legs or face, decreased urine output, or changes in urine color. Other signs include nausea, confusion, high blood pressure, and persistent itching. Lab abnormalities like elevated creatinine, BUN, or protein in urine detected in a KFT often appear before physical symptoms manifest. Such findings indicate underlying issues like kidney disease, dehydration, or urinary obstructions. Early testing is crucial for individuals with these symptoms to prevent worsening of kidney health.
