| Test Name/Synonym: | Sulfite Screen (Synonyms: Molybdenum Cofactor Deficiency, Sulphite Oxidase, Sulfite Oxidase) | ||||||
| Clinical Indications: | This dipstick screening test is for the investigation of patients suspected of having isolated sulfite oxidase, or molybdenum co-factor deficiencies, based on clinical presentation.
Confirmation of a positive sulfite screen, or investigation of patients suspected of having isolated sulfite oxidase or molybdenum co-factor deficiencies based on clinical presentation but for which a specimen will not reach the lab within the required timeframe of specimen stability, should order urine S-Sulfocysteine Panel testing. | ||||||
| Collection Alert: | For south sector, collections are recommended to be performed at the Alberta Children’s Hospital.
Before collection of specimens, call Alberta Children’s Hospital (ACH) Biochemical Genetics lab 403-955-7379 or University of Alberta Hospital (UAH) Biochemical Genetics lab 780-407-8820. Collect Monday to Friday before 1400 hours (excluding holidays) only. | ||||||
| Shipping and Handling Alert: | Specimen must arrive at the testing lab within 1 hour of collection. | ||||||
