| Test Name/Synonym: | Reducing Substances, Urine (Synonyms: Benedict’s Test, URED) | ||||||
| Clinical Indications: | This screen is a simple and rapid method for the initial investigation for disorders of galactose and fructose metabolism.
This test should not be used to monitor known patients on treatment as this is a qualitative test. | ||||||
| LABID (Connect Care): | LAB554 | ||||||
| Test Code: |
| ||||||
| Specimen Type: | Urine | ||||||
| Primary Container: | Sterile container | ||||||
| Alternate Containers: | Non sterile container | ||||||
| Minimum Collection Volume: | 1.0 mL | ||||||
| Specimen Collection Requirements: | First morning void is preferred. Collect a 5.0 to 10.0 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. | ||||||
| Transportation: | Transport frozen specimens on dry ice. Samples must not thaw during transport. Transport to Biochemical Genetics at Alberta Children’s Hospital. | ||||||
| Method: | Benedict’s test | ||||||
| Method and Interpretation of Results: | Increased urinary reducing substances (e.g., galactose, fructose, glucose) are detected using Benedict’s test. Positive and negative controls are run with patient samples.
A positive Benedict’s test indicating the presence of increased urine reducing substances will result in reflexive sugar chromatography testing on the same sample, volume permitting. | ||||||
