Hemoglobin A1c (HbA1c) with 24-hour urine collection for total urinary creatinine
This test measures your average blood sugar levels over the past 2–3 months and checks your kidney function through urine creatinine. It helps track diabetes management and kidney health.
["Assesses long-term blood sugar control and kidney function in tandem."]

What HbA1c Measures
HbA1c reflects the percentage of hemoglobin molecules attached to glucose over time, giving a snapshot of your blood sugar trends. It’s a key tool for diagnosing diabetes and monitoring treatment effectiveness.
Why Urine Creatinine Matters
Urine creatinine helps evaluate kidney function by measuring waste product excretion. Together with HbA1c, this profile provides a broader health picture, especially in patients with diabetes or suspected kidney issues.
How the Test Works
Your blood is tested for HbA1c levels, while a 24-hour urine sample is collected to measure creatinine. This combined approach ensures accurate tracking of both blood sugar and kidney health simultaneously.
When You Might Need This Test
This test is typically ordered for people with diabetes to monitor treatment progress, those with suspected kidney problems, or individuals at higher risk for metabolic or kidney-related conditions.

Frequently asked questions
HbA1c alone can miss short-term blood sugar spikes, while creatinine alone doesn’t reflect glucose control. Combining these tests helps detect complications like diabetic nephropathy (kidney damage) earlier, guiding better management strategies.
A 24-hour urine sample provides a more accurate measure of creatinine excretion, accounting for daily variations in kidney function and urine output. This helps assess kidney performance consistently over time.
High HbA1c suggests poor blood sugar control, while elevated creatinine may indicate kidney strain. Both results should be discussed with your healthcare provider to adjust treatment plans, such as diet, medication, or monitoring frequency.
