Biopsy specimen, 0.2g duodenal biopsy wrapped in foil in sterile container. (Specimen will be collected by the referring clinician).

The tissue sample must be frozen immediately after collection as follows:

1. Wrap (fold) the tissue sample in parafilm first.
2. Then wrap the sample in foil.
3. Place in sterile container and freeze ASAP.
4. Send on dry ice.

Do not place tissue in saline or formalin.

Specimens should be transported in a manner that does not compromise the ability to be tested. 

• Frozen samples should remain frozen during transport. 
• Samples unable to be frozen should be transported at 4°C until they can be frozen.

Add ons for this test cannot be performed.
