Case Study 📚
Patient Overview
A 42-year-old patient presented with:
- Persistent fatigue
- Shortness of breath
- Dizziness
Laboratory Findings
| Test | Result |
|---|---|
| Hemoglobin | Low |
| MCV | Low |
| Ferritin | Very Low |
| RBC Count | Slightly Low |
Diagnosis
Iron Deficiency Anemia
Intervention
The physician prescribed:

Frequently Asked Questions ❓
What is the purpose of hematology?
Hematology studies blood and blood disorders to support disease diagnosis, treatment, and monitoring.
Is Hematology in Practice (2nd Edition) suitable for beginners?
Yes. It introduces core concepts while also covering practical laboratory techniques useful for advanced learners.
What is a Complete Blood Count (CBC)?
A CBC is one of the most common laboratory tests, measuring red cells, white cells, platelets, hemoglobin, hematocrit, and related indices.
Why are automated hematology analyzers important?
They improve speed, accuracy, reproducibility, and efficiency while reducing manual errors in high-volume laboratories.
Why is microscopic examination still necessary?
Blood smear review can reveal abnormal cell shapes, immature cells, parasites, or platelet clumps that automated systems may not fully characterize.
