Extract
- Blood smear denotes microscopic examination of the peripheral blood, performed by
a physician on a peripheral blood film stained with the May–Grünwald–Giemsa
method.
- Blood cell morphology
- Differential white cell count is performed with an automated blood cell counter and only abnormal samples ("flagged", about 10–20%) are checked microscopically by a laboratory technician. Depending on the skills of the technician and the local practices, she/he may give comments that provide information partly similar to the morphological examination proper.
