The Niemann-Pick Disease Test helps diagnose a rare inherited condition that affects how the body processes fats. It is ordered when a person has symptoms like an enlarged liver or spleen, developmental delays, or a family history of the disease.
What it measures
- Acid sphingomyelinase (ASM) enzyme activity — Measures how well this enzyme breaks down fats in cells; low activity can suggest Niemann-Pick disease type A or B.
- Genetic testing for SMPD1 gene mutations — Looks for changes in the gene that provides instructions for making ASM.
- Cholesterol trafficking tests (for type C) — Checks how cells move cholesterol; problems can indicate Niemann-Pick disease type C.
- NPC1 and NPC2 gene mutations — Identifies gene changes linked to type C when other tests are unclear.
Who it is for
A doctor may order this test for someone with unexplained liver or spleen enlargement, neurological symptoms, or a family history of Niemann-Pick disease. It is not a routine screening test.
Preparation
No fasting or special preparation is usually needed for this blood test. Follow any instructions from your healthcare provider.
Results and what they mean
Results are reported as enzyme activity levels or as positive or negative for gene mutations. A specialist interprets these results along with symptoms and other tests. This is general information, not medical advice; talk with your clinician about your results.
