PA13.1-3 | Welcome to Hematopoiesis & Blood Specimen Basics
Learning Objectives
- Trace the hierarchy of haematopoiesis from the pluripotent stem cell to each mature blood lineage, including the role of growth factors
- Explain erythropoiesis step-by-step and identify the morphological stages visible on a peripheral blood smear
- Describe extramedullary haematopoiesis — where it happens, why it happens, and what you'll find clinically
- Select the correct blood collection tube for a given haematology or coagulation test, and explain what happens when the wrong tube is used
- Outline the steps of peripheral blood smear preparation and state why each step matters
INSTRUCTIONS
Haematology is the discipline where pathology becomes visceral. Every CBC you order, every smear you read, every bleeding patient you try to understand — it all anchors back to two questions: how was this blood made, and was the sample collected correctly? This module builds that double foundation. Competency PA13.1 (KH — Knows How) takes you inside the bone marrow factory. Competency PA13.3 (SH — Shows How) puts a needle in your hand and asks: which tube do you reach for, and why does it matter? Both questions are testable on Day 1 of your clinical posting — and Day 1 of the final theory paper.
