Microalbumin/Creatinine Ratio (ALB/CRESU)

Price: 15 د.ا

Normal Range

– Females: Less than 30 mg/g

– Males: Less than 30 mg/g

– Children: Typically, similar to adults; less than 30 mg/g (Consult a pediatrician for specific age-related norms)

Function in the Body

The Micro albumin/Creatinine Ratio measures the amount of albumin in the urine compared to creatinine. Albumin is a protein that helps maintain blood volume and pressure by retaining fluid in the bloodstream. Creatinine is a waste product produced by muscle metabolism and is excreted by the kidneys. This test helps assess kidney function and detect early signs of kidney damage.

Diseases Revealed by the Test

– Diabetic Nephropathy: Early kidney damage due to diabetes

– Hypertensive Nephropathy: Kidney damage due to high blood pressure

– Chronic Kidney Disease (CKD): Progressive loss of kidney function

– Glomerulonephritis: Inflammation of the kidney’s filtering units

Symptoms Indicating the Need for the Test

– Persistent high blood pressure

– Diabetes, particularly Type 1 and Type 2

– Swelling in the hands, feet, or face (edema)

– Fatigue and generalized weakness

– Unexplained changes in urine color or volume

Symptoms of Deficiency and Overdose

The test specifically measures a ratio and doesn’t directly indicate deficiency or overdose. However, abnormal levels of albumin in the urine can signal kidney dysfunction or damage. High levels (albuminuria) may indicate a greater risk for cardiovascular disease, while low levels are usually not a concern but can reflect certain conditions like dehydration.

Diagnosis

A high Micro albumin/Creatinine Ratio may indicate kidney damage or disease, often necessitating further diagnostic tests, such as:

– Blood tests (serum creatinine, blood urea nitrogen)

– Imaging studies (ultrasound, CT scan)

– Kidney biopsy (in some cases)

Frequently Asked Questions

1. What causes an elevated Microalbumin/Creatinine Ratio?

Conditions such as diabetes, hypertension, and certain kidney diseases can cause elevated levels.

2. How is the test performed?

The test typically requires a urine sample, either a random sample or a timed collection (24-hour urine sample).

3. Can medications affect the test results?

Yes, certain medications, such as NSAIDs, ACE inhibitors, and diuretics, can influence the results. Inform your healthcare provider of any medications you are taking.

4. How often should the test be repeated?

For individuals with diabetes or hypertension, the test is often repeated annually or more frequently as advised by a healthcare provider.

5. Is the test painful?

No, it is a non-invasive test that only requires a urine sample.

6. Can lifestyle changes impact the results?

Yes, controlling blood sugar levels, blood pressure, and maintaining a healthy diet can help improve or stabilize the Micro albumin/Creatinine Ratio.
