Toxoplasma gondii, Molecular Detection, PCR
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.
Specimen source is required.
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Amniotic fluid
Container/Tube: Amniotic fluid container
Specimen Volume: 0.5 mL
Collection Instructions: Do not centrifuge.
Specimen Stability Information: Refrigerated (preferred)/Frozen
Specimen Type: Spinal fluid
Container/Tube: Sterile vial
Specimen Volume: 0.5 mL
Collection Instructions: Do not centrifuge.
Specimen Stability Information: Refrigerated (preferred)/Frozen
Specimen Type: Fresh tissue
Container/Tube: Sterile container with 1 to 2 mL of sterile saline or multi-microbe medium (M5) (Supply T484)
Specimen Volume: Entire collection
Collection Instructions: Submit only fresh tissue
Specimen Stability Information: Refrigerated
Specimen Type: Ocular fluid
Container/Tube: Body fluid container
Specimen Volume: 0.3 mL
Collection Instructions: Do not centrifuge.
Specimen Stability Information: Refrigerated (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.
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis | NA |
| Lipemia | NA |

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
| Specimen Type | Temperature | Time |
|---|---|---|
| Varies | Varies | 7 days |
