Test ID: ACANT    
Acanthamoeba/Naegleria species, Corneal Scraping or Spinal Fluid

Specimen Type Describes the specimen type needed for testing

Varies

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.

 

Specimen source is required.

 

Submit only 1 of the following specimens:

 

Specimen Type: Central nervous system tissue

Container/Tube: Sterile container with 1 mL of saline or minimal essential medium

Specimen Volume: Entire collection

Specimen Stability Information: Ambient

 

Specimen Type: Contact lens, corneal scraping, corneal tissue

Container/Tube: Sterile container with 1 mL of saline or minimal essential medium

Specimen Volume: Entire collection

Additional Information: The preferred specimen for Acanthamoeba culture from an ocular source is corneal scraping or biopsy. Swab is suboptimal and may result in a falsely negative result. Supplementary slides may be submitted in addition to the scraping or biopsy, but slides alone will not be accepted for testing.

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Specimen Type: Contact lens solution

Container/Tube: Sterile container

Specimen Volume: 2 mL

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Specimen Type: Spinal fluid

Container/Tube: Sterile vial

Specimen Volume: 1 mL

Specimen Stability Information: Ambient

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.

Contact Lens Solution: 1 mL/Spinal Fluid: 0.5 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

Hemolysis

NA

Lipemia

NA

Icterus
