N- Acetyl Glucosamine 6 Sulphate Sulphatase Blood

This test measures the levels of N-Acetyl Glucosamine 6 Sulphate Sulphatase enzyme in your blood.

• To diagnose Sanfillipo D or MPS III D, a rare genetic disorder
• To monitor the progression of the disease
• To evaluate the effectiveness of treatment

This test may be recommended if you or your child has symptoms suggestive of Sanfillipo D or MPS III D, such as developmental delays, hearing loss, behavioural problems, or seizures. It is also advised for individuals with a family history of the condition or those at risk due to genetic factors.

Abnormal results may indicate the presence of Sanfillipo D or MPS III D. Your doctor will interpret the results in conjunction with your medical history and other diagnostic tests to make a definitive diagnosis.

For this test, a small blood sample will be drawn from a vein in your arm. The sample is then sent to a laboratory for testing.

Inform your doctor about any medications, supplements, or medical conditions you have. Also, tell them if you have any specific requirements.

Your doctor may recommend stopping certain medications temporarily if they could interfere with the test results.

Other tests that may be ordered alongside N-Acetyl Glucosamine 6 Sulphate Sulphatase Blood include genetic testing to confirm the diagnosis of Sanfillipo D or MPS III D, as well as additional enzyme activity tests to evaluate other metabolic disorders associated with similar symptoms.

Sanfillipo D enzyme assay or MPS III D enzyme assay

Sanfillipo D, also known as MPS III D, is a rare genetic disorder characterised by the body's inability to break down certain substances. This leads to the accumulation of these substances in the body, causing progressive neurological symptoms and physical abnormalities.
