Interpretive Data:
A PTT mix panel is performed to screen for a factor deficiency or
inhibitor.
Comments:
A MIX testing panel should have its own draw tube and not be combined
with other coagulation tests or panels to ensure an adequate amount of
plasma for testing.

Methodology:
Optical clot detection.
Sample
Processing:
Centrifuge within four hours of draw time.
Centrifuge at a speed and time necessary to get barrier separation of plasma/serum and cells.
Separate plasma into plastic container and cap (glass is not acceptable).
Centrifuge a second time to ensure platelet poor plasma and separate plasma into a new, labeled plastic tube, cap.
