Immunoglobulin M (IgM) Antibody to *Ureaplasma urealyticum* (24-hour urine collection)

Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like persistent urinary issues, recurrent infections, or if you’ve been exposed to *Ureaplasma urealyticum*. It helps determine if your body has mounted an immune response to this bacterium, which can sometimes cause low-grade infections.

How the Test Works

A urine sample is collected over 24 hours to capture any bacteria or immune markers. The sample is then tested for IgM antibodies, which indicate an active immune response to *Ureaplasma urealyticum*. The test does not directly measure bacteria but assesses your body’s reaction.

Sample Collection

You’ll need to collect all urine produced in a 24-hour period (typically from midnight to midnight) in a sterile container. Empty your bladder before starting and discard the first urine sample. Use clean containers and refrigerate the sample if not processed immediately.

What to Expect

No special preparation is needed, but avoid antibiotics or certain medications that could interfere with results. Follow your provider’s instructions carefully for accurate testing.
