The word “Hema” means blood and
“ology” means science, hence the word Hematology means the study of blood cells.
Hematology is interested in the production, life span, and destruction of cells
in the blood sample.
We are interested in white blood
cells or leukocytes, red blood cells or erythrocytes and
platelets. Technology is used to study these types of cells contained in
a complete blood count. The Complete Blood Count allows the physician to diagnose and monitor infection, anemia,
leukemia as well as monitoring blood loss or decreased production of the various
cells required by the body.
Hematology at RVH utilizes an
automated cell counter. The purpose of the instrument is to identify patient
samples with normal parameters from patients with abnormal samples requiring
additional studies. These studies may
include further measurement of cell size, platelet distribution, manual white blood cells
differential or any other definitive tests that assists the physician in
diagnosing the patient’s condition.
The Hematology department also
performs cell counts on other body fluid samples such spinal fluid,
pleural and synovial fluids. The physician is interested in the presence and
number of red and white cells.
Coagulation testing, a sub-specialty
in Hematology, studies the “factors” in the patient’s plasma which are
responsible for the clotting of blood. The physician is interested in these
results when monitoring anticoagulant therapy (such as Coumadin or Heparin).
must be analyzed within 4 hours of collection for accuracy and sample
integrity. These tests are also a useful screening test to indicate
deficiencies that may result from secondary causes like Vitamin K deficiency,
liver disease, Hemophilia, Disseminated Intravasular Coagulation, Deep
Vein Thrombosis, Pulmonary Embolism or hereditary coagulation
