Q

Differences between Acute and Chronic Leukemia
Differential:
Anemia :
Platelets :
Others aged lymphoid:
Methods used to diagnose:

A

Acute Leukemia:
- Blasts usually present
- Mild to severe
- Mild to severe ↓
- Usually lymphoid in children, myeloid in adults
- Peripheral blood smear, bone marrow Same but less use of cytochemical stains examination, cytochemical stains, immunophenotyping, cytogenetics, molecular genetics

Chronic Leukemia:
- More mature cells
- Mild
- Usually N
- Myeloid mostly in young to middle-in older adults. Most go into blast crisis
- Same but less use of cytochemical stains
