Correct Answer is B
Explanation
A. C-reactive protein (CRP): CRP is typically tested using a serum sample collected in a gold or red-top tube, not a light blue tube.
B. Partial thromboplastin time (PTT): PTT is a coagulation test that requires a light blue top tube containing sodium citrate, which acts as an anticoagulant. This tube is specifically used for coagulation studies.
C. Glucose: Glucose levels are commonly measured using a gray-top tube containing sodium fluoride to inhibit glycolysis, not a light blue tube.
D. Lactate: Lactate levels are typically measured using a gray-top tube or green-top tube, depending on the specific protocol, not a light blue tube.
Correct Answer is C
Explanation
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.
D. Mix the anticoagulant in the tube after filling the tube: The anticoagulant should be mixed by inverting the tube immediately after filling it, not after the fact.
