✍️ Sample ASCP Questions & Answers
1. 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.
2. 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.
3. 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.
4. 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.
5. Which method is considered the MOST reliable for identifying outpatients who lack a hospital armband?
A government-issued photo ID is the most reliable method for identifying outpatients because it provides visual verification.
6. Which of the following actions helps prevent a hematoma during venipuncture?
Applying direct pressure to the puncture site for 3-5 minutes after needle removal is the primary method to prevent hematoma formation.

What Practice Test Geeks adds beyond an AI chat for ASCP
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length ASCP mock exam — 80 questions in 120 minutes with a 400% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed ASCP question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable ASCP cheat sheet you can print or save as a PDF.
- ASCP flashcards built from the same question bank.
- Free ASCP practice tests with the correct answer shown after each question.
