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.
