Test ID: LSDS
Lysosomal Storage Disorders Screen, Random, Urine
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
The following algorithms are available in Special Instructions:
-Lysosomal Storage Disorders Diagnostic Algorithm, Part 1
Specimen Type Describes the specimen type validated for testing
Ordering Guidance
This test is the recommended screening test for the initial workup of a suspected lysosomal storage disorder (LSD) when the patient's clinical features are not suggestive of any particular LSD.
Necessary Information
1. Patient's age is required.
2. Biochemical Genetics Patient Information (T602, in Special Instructions) is recommended. This information aids in providing a more thorough interpretation of results. Send information with specimen.
Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Patient Preparation: Do not administer low-molecular weight heparin prior to collection. Baby wipes or wipes containing soaps and lotions should not be used prior to collection because these may interfere with results.
Supplies: Urine Tubes, 10 mL (T068)
Container/Tube: Plastic, 10-mL urine tube
Specimen Volume: 10 mL
