This test evaluates the activity of 6 enzymes associated with the following lysosomal storage diseases: Fabry disease, Gaucher disease, Krabbe disease, MPS I (Hurler syndrome), Niemann-Pick disease and Pompe disease

This enzyme panel may be appropriate for individuals with a clinical suspicion of lysosomal storage disorders and/or individuals with a family history of lysosomal storage disorders.

The lysosomal storage disorders (LSD) are a diverse group of inherited conditions caused by the defective function of specific lysosomal proteins. It is estimated that there are more than 50 different types. The disease course of these conditions is generally progressive, but the age of onset, nature and severity of symptoms can be variable between the disorders. Common symptoms of lysosomal disorders include hepatosplenomegaly, coarsening of facial features, short stature, corneal clouding, dysostosis multiplex and neurological regression. The combined prevalence of LSDs is estimated to be 1 in 7,000 births.

Tandem mass spectrometry analysis can be coupled with liquid chromatography, a technique referred to as LC-MS/MS. In this methodology, chromatography is used to separate analytes of interest prior to measurement by the mass spectrometer. This separation reduces interference from matrix components and can also allow for the measurement of analytes that have the same mass (isobaric species), thereby improving analytical specificity compared to MS/MS.

Dried Blood Spots
Collection Container(s):

Dried blood spot card


Follow kit instructions. Briefly, allow blood to saturate the card until indicated areas are filled and blood has soaked through the card. Air dry the card at ambient temperature for at least 3 hours.

  • NBS: Please contact Revvity Omics to request the StepOne® kit.
  • Gene Sequencing: Please contact Revvity Omics to request the DBS collection kit.
  • For pre-punched DBS: The required minimum is 6 punches
Condition: Follow the instructions provided with the collection set. Store the dried blood at ambient temperature for up to two days. If the specimen cannot be sent as soon as it is dry, the filter paper should be placed in a sealable plastic bag and stored in a refrigerator (≤ 8°C) or preferably in a freezer.
Shipping: Follow kit instructions. Double bag and ship overnight at ambient temperature.
Whole Blood (EDTA)
Collection Container(s):

EDTA (purple top)


Infants (< 2-years): 2 to 3 mL; Children (>2-years): 3 to 5 mL; Older children and adults: Minimum 5mL. The blood tube should be inverted several times immediately after blood collection to prevent coagulation.

Condition: Store at ambient temperature. Do not refrigerate or freeze.
Shipping: Ship overnight at ambient temperature ensuring receipt within 5-days of collection.
Clotted or hemolyzed samples are not accepted.
