Test ID: FEHA    
Entamoeba histolytica Antigen, EIA

Specimen Type Describes the specimen type needed for testing

Fecal

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.

Collect 2 grams fresh unpreserved stool in a sterile container. Send specimen frozen.

 

NOTE: Separate specimens must be submitted when multiple tests are ordered.

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.
