Acid mucopolysaccharides is a test that measures the amount of mucopolysaccharides released into the urine over a 24-hour period.
Mucopolysaccharides are long chains of sugar molecules found throughout the body, often in mucus and in fluid around the joints.
A 24-hour urine sample is needed.
There is no special preparation needed.
The test involves only normal urination, and there is no discomfort.
This test is done to diagnose a rare group of genetic disorders called mucopolysaccharidoses, including Hurler syndrome.
This test is usually only done in infants who have a family history of one of these disorders.
