Test ID: MTBS
Microsporidia Stain
Specimen Type 
Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Forms: If not ordering electronically, submit a Microbiology Request Form (Supply T244) with the specimen.
Patient should avoid use of anti-diarrheal medication (ie, loperamide or Pepto-Bismol).
The presence of barium will interfere with this test.
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Preserved stool
Container/Tube:
Preferred: ECOFIX preservative (Supply T219)
Acceptable: Container with 10% formalin
Specimen Volume: 5 g
Collection Instructions: See Stool Collection Information Sheet in Special Instructions.
Specimen Stability Information: Ambient (preferred)/Refrigerated/Frozen
Additional Information: Formed stool specimens seldomly yield microsporidial organisms.
Specimen Type: Unpreserved stool
Container/Tube: Stool container (Supply T288)
Specimen Volume: 5 g
Collection Instructions: See Stool Collection Information Sheet in Special Instructions.
Specimen Stability Information: Refrigerated <3 days (preferred)/Frozen
Additional Information: Formed stool specimens seldomly yield microsporidial organisms.
Acceptable:
Specimen Type: Duodenal aspirate
Container/Tube: Sterile container
Specimen Volume: 0.5 mL
Specimen Stability Information: Refrigerated <3 days (preferred)/Frozen
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
