✍️ Sample ASCP Questions & Answers
1. Which specimen type requires cold agglutinin precautions during collection and transport?
Cold agglutinin specimens must be kept warm (37 degrees C) because cold agglutinins cause red blood cells to clump at lower temperatures.
2. What is the clinical significance of a blood culture that becomes positive within 12-24 hours?
Blood cultures positive within 12-24 hours indicate high organism concentration and are associated with more severe infections.
3. Which department is responsible for performing blood typing and crossmatching?
The blood bank (immunohematology) department is responsible for blood typing, crossmatching, antibody screening, and ensuring compatible blood products for transfusion.
4. Why must light blue-topped coagulation tubes be filled to the exact fill line?
Light blue coagulation tubes require a precise 9:1 ratio of blood to sodium citrate. Underfilling or overfilling alters this ratio and produces inaccurate coagulation results.
5. What is the consequence of failing to maintain proper chain of custody for a forensic blood specimen?
If chain of custody is broken, the specimen's integrity cannot be guaranteed, and the results may be deemed inadmissible as evidence in legal proceedings.
6. What is the purpose of the rubber sleeve inside an evacuated tube holder?
The rubber sleeve in the tube holder covers the internal needle and prevents blood from leaking into the holder when tubes are removed and exchanged during multi-tube collection.
