| Test Mnemonic: TOXOPCR | |
|
Methodology: Polymerase Chain Reaction
Performed: Tue, Fri Reported: 1-5 days |
| Specimen Required: | |
|
Collect: One 7 mL plain red or SST, one 5 mL lavender (EDTA) or pink (K2 EDTA). (Spin blood samples and remove serum or plasma before transporting), amniotic fluid, CSF, or biopsy tissue (freeze tissue immediately). Specimen source is required.
Transport: 1 mL serum, plasma, amniotic fluid, or CSF in a sterile container, frozen. Fresh tissue, snap frozen on dry ice. Submit specimen according to Biological Substance, Category B, shipping guidelines. Pediatric Collection/Transport: 0.25 mL serum, plasma, or CSF in a sterile container, frozen. Less volume may decrease the sensitivity of the assay. Fresh tissue, snap frozen on dry ice. Submit specimen according to Biological Substance, Category B, shipping guidelines.
