This immunoturbidimetric test detects albumin in the urine and assesses the presence of kidney damage.

Results from this test may inform on the prognosis and management of chronic kidney disease, especially at early stages.1  

This test has been the gold standard for measuring urinary albumin excretion since 1987. It is also known as the immunoturbidimetric assay and has completely replaced the old urinary dipstick method.2

Random urine and 24-hour urine specimens can be tested. The 24-hour urine collection should start after the first-morning void and include all subsequent voids up to the first void of the next morning. Refrigerate the urine during and after collection. 

Yes. The patient should avoid exercise for 24 hours before specimen collection because it may elevate urinary albumin excretion.

Urinary tract infections, menstrual bleeding, fever, congestive heart failure, marked hyperglycemia, and marked hypertension may elevate urinary albumin excretion.

The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines state that an increased albumin level (≥30 µg/mg or ≥30 mg/24 creatinine) for more than 3 months is diagnostic of chronic kidney disease.1
