WBC is medical shorthand for White Blood Cells.
WBC’s are the body's first line defense against disease, and help fight infections.
They are also involved in reactions to allergies, tumors, and stress in general.
RBC is medical shorthand for Red Blood Cells.
RBCs transport hemoglobin. Hemoglobin transports oxygen. The amount of oxygen body tissues receive depends on the amount and function of RBCs and hemoglobin. RBCs normally survive about 120 days in the blood.
Specialized “clean-up” cells in the spleen and liver then remove them.
Hemoglobin is the protein that carries oxygen in the blood. It is contained in red blood cells. Both high and low hemoglobin counts indicate defects in the balance of red blood cells in the blood, and may indicate disease.
Lymphocytes are specialized WBCs whose purpose are to identify and destroy invading antigens.
These cells are important to the body\'s defense against infection, especially from viral infection.
Lymphocytes that mature in the Bone Marrow are called B-cells, and those that mature in the
Thymus organ are called T-cells.
Neutrophils are specialized WBCs, filled with tiny sacs of enzymes that help to kill and digest microorganisms it has engulfed. An increased proportion of neutrophils in the blood are a common finding with acute bacterial infections. A decreased proportion of neutrophils may be seen with viral infections and after radiotherapy and chemotherapy.
Monocytes- are specialized WBCs derived from bone marrow, which circulate in the blood briefly
before entering the tissues in which they become macrophages. Macrophages phagocytize (ingest)
are large particles and cellular debris that neutrophils cannot handle.
MCH is medical shorthand for Mean Corpuscular Hemoglobin. This number represents a measurement
of the average hemoglobin concentration within red blood cells. Elevations can be caused by too little
vitamin B12 or folate, and decreases can be seen in iron deficiency.
MCHC is medical shorthand for Mean Corpuscular Hemoglobin Concentration. It is an estimate of the concentration (amount) of hemoglobin in a given number of packed red blood cells.
MCV is medical shorthand for Mean Corpuscular Volume. This number represents the size or volume
of the average RBC within a sample. I creases or decreases in MCV can point to specific anemias.
Platelets are irregularly shaped, colorless bodies that are present in blood. Their sticky surface lets them, along with other substances, form clots to stop bleeding. When bleeding from a wound suddenly occurs, the platelets gather at the wound and attempt to block the blood flow. The mineral calcium, vitamin K, and a protein called fibrinogen help the platelets form a clot.
