Microalbumin, Spot Urine (MICSU)

Price: 15 د.ا

The Microalbumin, Spot Urine test measures the concentration of albumin in a single urine sample. Albumin is a type of protein normally present in the blood, and its presence in urine can indicate kidney health. This test is particularly useful for detecting early signs of kidney damage, especially in individuals with conditions like diabetes and hypertension.

Normal Range

• Female: Less than 30 mg/g creatinine
• Male: Less than 30 mg/g creatinine
• Children: Less than 22 mg/g creatinine

Function in the Body

• Maintaining Oncotic Pressure: Albumin helps maintain osmotic balance in the blood, preventing fluid leakage from blood vessels.
• Transport of Substances: It acts as a carrier for hormones, vitamins, and drugs, facilitating their movement through the bloodstream.
• Buffering: Albumin helps buffer blood pH, maintaining a stable internal environment.

Diseases Revealed by the Test

• Diabetic Nephropathy: Early kidney damage due to diabetes can lead to microalbuminuria.
• Hypertension: High blood pressure can damage the kidneys, causing albumin to leak into the urine.
• Chronic Kidney Disease (CKD): The presence of albumin in urine can be an early sign of CKD.
• Cardiovascular Disease: Elevated urinary albumin levels can indicate an increased risk of cardiovascular issues.

Symptoms

While microalbuminuria itself may not cause noticeable symptoms in its early stages, underlying conditions may present with:

• Swelling: Especially in the legs, ankles, or around the eyes due to fluid retention.
• Fatigue: Unexplained tiredness or weakness.
• Frequent Urination: Particularly at night.

Symptoms of Deficiency and Overdose

• Deficiency: Low levels of albumin in urine are generally a healthy sign; however, low albumin in blood (hypoalbuminemia) can cause swelling, fatigue, and poor wound healing.
• Overdose: Excessive albumin in urine (albuminuria) is a sign of an underlying issue, such as kidney damage or disease.

Diagnosis

The test involves collecting a single urine sample and analyzing the albumin-to-creatinine ratio (ACR). An ACR of less than 30 mg/g is considered normal, levels between 30-300 mg/g indicate microalbuminuria, and levels above 300 mg/g suggest macroalbuminuria.

Frequently Asked Questions

1. Who should get a MICSU test?
   Individuals with diabetes, hypertension, or a family history of kidney disease are advised to undergo regular MICSU testing to detect early kidney damage.
2. How is the MICSU test different from a 24-hour urine test?
   The MICSU test requires a single urine sample, making it more convenient than a 24-hour urine collection, though the latter may provide more detailed information in some cases.
3. Can lifestyle changes impact the results of a MICSU test?
   Yes, maintaining a healthy diet, regular exercise, and controlling blood pressure and blood sugar levels can help reduce albumin leakage in urine.
4. Is the MICSU test painful?
   No, the test is simple and painless, involving only the collection of a urine sample.
5. Can medications affect the results of the MICSU test?
   Certain medications may affect the results, so it is important to inform your healthcare provider of any medications you are taking before the test.
