Clinical Laboratory Sections:
- Hematology: Cellular elements (RBCs, WBCs, platelets) are enumerated and classified in all body fluids and bone marrow.
- Coagulation: The overall process of hemostasis is evaluated, including platelets, blood vessels, coagulation factors, fibrinolysis, inhibitors, and anticoagulant therapy (heparin and Coumadin).
- Clinical Chemistry: This is the most automated area.
- Clinical Chemistry performs electrophoresis, therapeutic drug monitoring and performs enzyme immunoassays to measure substances such as proteins, carbohydrates, enzymes, hormones, and toxicology.
- Blood Bank (Immunohematology): Blood is collected, stored, and prepared for transfusion here.
- Testing procedures in the blood bank involve RBC antigens (Ag) and antibodies (Ab).
- Blood from patients and donors is tested for its blood group (ABO) and Rh type.
- Compatibility (crossmatch) testing between patient and donor performed.
- Abnormal antibodies are also detected and identified.
- Serology (Immunology): Tests are performed to evaluate the body's immune response, antibodies (immunoglobulins), and cellular activation.
- Microbiology: Responsible for identifying pathogenic microorganisms for hospital infection control; section may be divided into bacteriology, mycology, parasitology, and virology.
- Common tests in Microbiology include Culture and Sensitivity, and Gram Staining.
- Urinalysis: (UA) may be a separate laboratory section or part of hematology or chemistry.
