| Test Name/Synonym: | Oligosaccharides Screen (Synonyms: Oligosaccharidoses, Lysosomal Storage Disorders) | ||||||||
| Clinical Indications: | This test is for the screening of several oligosaccharide degradation disorders and should be ordered when appropriate clinical presentations are identified. | ||||||||
| Ordering Alert: | This test is considered specialty testing and should NOT be ordered without appropriate clinical indications.
This is a qualitative screening test for multiple oligosaccharidosis that may not identify a single disorder. Abnormal results should be confirmed by targeted enzyme or molecular genetic tests based on clinical presentation. | ||||||||
| LABID (Connect Care): | LAB4029A | ||||||||
| Test Code: |
| ||||||||
| Specimen Type: | Urine | ||||||||
| Primary Container: | Sterile Container | ||||||||
| Alternate Containers: | Non Sterile Container | ||||||||
| Minimum Collection Volume: | 5.0 mL | ||||||||
| Specimen Collection Requirements: | Collect a 5 to 10 mL random urine specimen. | ||||||||
| Test Resources: | Submit request using the applicable requisition or Connect Care online order entry:
| ||||||||
| Stability and Storage: | Frozen | ||||||||
| Processing: | Specimen can be submitted in primary container or aliquot tube. If specimen is transferred to secondary aliquot tube or container, write "urine" on label. Freeze specimen immediately. | ||||||||
| Transportation: | Transport frozen specimens on dry ice. Samples must not thaw during transport. | ||||||||
| Method: | Thin layer chromatography (TLC) | ||||||||
| Method and Interpretation of Results: | Oligosaccharide pattern is determined using TLC and orcinol staining protocol. Patterns are visually assessed and interpretive report is provided.
Abnormal patterns can occur naturally during pregnancy, in breast-feeding infants or in individuals ingesting infant formula or food replacement containing oligosaccharides. Consider routine testing outside of these scenarios if possible. Abnormal pattern will reflex to include a referred out test for confirmation if sample volume is sufficient. | ||||||||
| Routine Turn Around Time: | 10 days | ||||||||
| Testing Schedule: | Weekly | ||||||||
| Reference Interval: | Interpretation provided on report. | ||||||||
