Hepatosplenomegaly Panel, Blood
Use
This test is used as a component of the initial evaluation of a patient presenting with hepatosplenomegaly. It serves as a screening test for select lysosomal and lipid storage disorders such as cerebrotendinous xanthomatosis, Gaucher disease, and Niemann-Pick disease types A, B, and C. Hepatosplenomegaly often presents due to chronic hepatic dysfunction or abnormal storage of lipids and other analytes. Screening aids in narrowing possible conditions due to the broad phenotypic variability and similarity of clinical features across different disorders.
Special Instructions
This test should not be used for monitoring patients with confirmed diagnoses. If monitoring is required, alternate tests such as CTXWB, GPSYW, or OXYWB should be considered. Send the whole blood specimen in its original tube, do not aliquot.
Limitations
The test does not identify all causes of hepatosplenomegaly. While a positive result can strongly suggest a diagnosis, it needs confirmation by stand-alone biochemical or molecular assay. Conditions like Wolman disease or cholestatic biliary atresia might mimic Niemann-Pick disease type C. It also does not differentiate carriers.
