A. Add thixotropic gel to the tube after venipuncture: Thixotropic gel is used in specific tubes for separating serum or plasma from blood cells and should be added during the manufacturing process, not after venipuncture.
B. Place the tubes in the centrifuge to chill after venipuncture to separate blood cells: Tubes should not be chilled before centrifugation unless specified by the test requirements. Most tubes are centrifuged at room temperature.
C. Invert additive tubes multiple times after filling the tube: Inverting additive tubes multiple times ensures proper mixing of the additive with the blood, which is crucial for accurate test results.
