Description
Estimated cost for Urine alpha-1-microglobulin at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
Urinary α1-microglobulin testing is primarily used to assess kidney function, specifically to detect early signs of tubular damage. It is also useful in monitoring the progression of kidney diseases, evaluating the effectiveness of treatments, and as a marker for renal involvement in systemic diseases such as diabetes and hypertension.
Normal Range
The normal range for urinary α1-microglobulin (α1-MG) is typically between 0-20 mg/L. This value can vary slightly depending on the laboratory and the specific method used for measurement.
Low Values - Possible Causes
Low values of urinary α1-microglobulin are less common and generally not clinically significant. However, they may be observed in cases of severe protein malnutrition, liver failure, or certain genetic conditions affecting protein synthesis.
High Values - Possible Causes
High values of urinary α1-microglobulin can indicate kidney damage, particularly tubular dysfunction. Common causes include diabetic nephropathy, glomerulonephritis, interstitial nephritis, heavy metal poisoning, and post-renal transplant complications.
