Hemoglobin A1c (HbA1c) with 24-hour urine collection for specific protein analysis (e.g., microalbuminuria)

What This Test Measures

The test involves collecting all urine produced in a 24-hour period and analyzing it for specific proteins, such as albumin or microalbumin. These proteins can indicate whether your kidneys are functioning normally or if there is an abnormal amount being lost in urine, which may signal conditions like diabetic nephropathy or early kidney disease.

Why It Matters in Your Health

Detecting protein in urine early can help doctors monitor kidney health, especially in people with diabetes, high blood pressure, or a family history of kidney disease. It may also help identify other conditions affecting protein metabolism.

How the Test Works

Your urine sample is collected in a container over 24 hours. The lab processes the sample to measure protein levels, often using sensitive methods like immunoassay or nephelometry to detect even small amounts.

What to Expect Before the Test

No special preparation is needed beyond collecting all urine in a container for the full 24-hour period. Drink enough water to produce urine throughout the day, but avoid excessive diuretics or medications that might affect urine protein levels unless instructed otherwise.
