Kidney profile test

Traditional serum creatinine (eGFR) testing may only reveal one side of the CKD story. For a more complete picture, guidelines recommend both the eGFR blood test and the urine albumin-to-creatinine ratio (uACR) test to assess kidney function and damage. 5 This combination enables early detection, essential to managing CKD progression. The Kidney Profile from Quest includes both tests, enabling earlier detection with just one test code. Quest offers the guideline-based testing you need to help diagnose CKD, manage disease progression, and establish follow-up testing frequency. You’ll also know when a referral to a nephrologist is recommended. The KDIGO guideline recommends using cystatin C–based eGFR, or creatinine plus cystatin C–based eGFR, to confirm CKD when creatinine-based eGFR indicates a mild to moderately high risk of CKD progression (45 to 59 mL/min/1.73 m2) in a patient without albuminuria. 6 In addition, cystatin C–based eGFR testing is less influenced by diet and muscle mass. This makes it more appropriate for patients in whom creatinine-based results may be misleading. 6 These conditions include pregnancy, acute illness, serious comorbid conditions, high or low extremes of muscle mass, malnutrition, vegetarian or low-meat diet, and creatine dietary supplement use. Beyond testing, Quest provides access to clinical algorithms and other educational resources, as well as advanced expertise on kidney health, to help you navigate care along the complex cardiometabol...
