Description
Urine Immunoglobulin A (IgA) testing helps assess kidney health—especially in suspected IgA nephropathy or glomerular disease—and costs ¥15–45 at partner hospitals in China, with ChinaMedicalHub assisting with booking and interpreter support.
Main Uses
The primary purpose of measuring Urinary Immunoglobulin A (IgA) is to diagnose and monitor IgA Nephropathy, a kidney disorder characterized by the deposition of IgA in the kidneys. It is also useful in assessing other conditions associated with increased IgA levels, such as certain infections and autoimmune diseases. This test is often ordered when there are signs of kidney damage, persistent hematuria, or proteinuria, and it helps in evaluating the progression and treatment response in patients with known IgA-related conditions.
Normal Range
The normal range for Urinary Immunoglobulin A (IgA) is typically less than 10 mg/L. However, this can vary slightly depending on the laboratory and the specific method used for measurement.
Low Values - Possible Causes
Low values of Urinary IgA are not commonly a concern and may be due to: 1. Normal variation, 2. Low production of IgA by the immune system, 3. Certain medications that suppress the immune system, 4. Rare genetic conditions affecting IgA production, 5. Lack of recent infections or inflammatory processes.
High Values - Possible Causes
High values of Urinary IgA may indicate: 1. IgA Nephropathy, 2. Infections, particularly in the urinary tract, 3. Inflammatory bowel diseases, such as Crohn's disease or ulcerative colitis, 4. Rheumatoid arthritis, 5. Other autoimmune disorders.
