Test Description

This test evaluates the activity of alpha-galactosidase A enzyme that has been associated with Fabry disease.

Indications for Testing

This test may be appropriate for individuals with a clinical suspicion of Fabry disease and/or individuals with a family history of Fabry disease.

Condition Description

Fabry disease is a lysosomal storage disorder with a wide spectrum of symptoms ranging from mild cases in females, to severe cases in classically affected hemizygous males. Symptoms may include abdominal and joint pain, vascular lesions and corneal abnormalities. Neurological symptoms include autonomic dysfunction and burning sensation or numbness in the extremities. Fabry disease affects an estimated 1 in 40,000 to 1 in 60,000 males. The prevalence is unknown in females.

Test Methods and Limitations

Flow injection analysis tandem mass spectrometry (FIA/MS/MS)

Detailed Sample Requirements

Dried Blood Spots
Test Details Page
Collection Container(s) Dried blood spot card
Collection

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