Albumin, Random Urine With Creatinine
Use
This test detects albumin in urine using an immunoturbidimetric assay and assesses the presence of kidney damage. Results can inform prognosis and management of chronic kidney disease, particularly in early stages. Measurement of albuminuria has been a gold standard since 1987, replacing the urinary dipstick method. A urine albumin‑creatinine ratio ≥30 µg/mg or ≥30 mg/24 h for over 3 months is diagnostic of chronic kidney disease. KDIGO guidelines reference these thresholds.

Special Instructions
Random urine and 24‑hour urine specimens are acceptable. For 24‑hour collections, start after the first‑morning void, include all voids through next morning’s first void, and refrigerate during and after collection. Patients should avoid exercise for 24 hours prior to collection because exercise may elevate albumin excretion. Conditions such as urinary tract infection, menstrual bleeding, fever, congestive heart failure, marked hyperglycemia, and marked hypertension may also elevate urinary albumin excretion.
