We didn’t invent the lab test,
We simply perfected it.
Back PARTIAL THROMBOPLASTIN TIME, ACTIVATED (PTT) | |
|---|---|
| Test Code: 282 | Specimen Collection: Plasma |
| Component: APTT | Method: Photo-Optical Clot Detection |
| Collection Notes: Draw to the proper fill level (do not overfill or underfill) because the correct ratio of blood to citrate is critical (9:1). Mix by gentle inversion 5-6 times. Hemolyzed or clotted specimens are not acceptable. Centrifuge and physically separate the plasma using a plastic transfer pipette into a separate plastic transfer tube. Freeze and transport frozen on dry ice. | |
| Clinical Utility: PTT is recommended for screening ONLY, and should NOT be used for heparin monitoring. | |
