Hematology Test | Normal values
Hematology is a branch of medical science that deals with study of blood cells and its disorder and hematology test values help health care worker to monitor the treatment and understand patent condition this include blood cells count like RBC count, WBC count, Platelet count, red cell indices
Purpose of hematology test
- Treatment of anemia
- evaluate erythropoietic activity
- Blood disorder
- Monitor treatment
- Dialysis
- Blood transfusion
- causes of infection
Hematology tests List
