Limitations:
The effect of anticoagulants on this assay has not been determined, therefore dried blood spots prepared from venous drawn whole blood tubes cannot be accepted.
Indications for Testing
Alpha-L-iduronidase activity is below the normal reference range.
Condition Description
Mucopolysaccharidosis type I (MPS I) is a rare autosomal recessive genetic disorder, caused by deficiency of the enzyme alpha-L-iduronidase, resulting in the accumulation of the glycosaminoglycans (GAGs) in organs and tissues (PMID: 32764324).

Detailed Sample Requirements
Dried Blood Spots
| 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.
|
| 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. |
