Introduction
Intestinal capillariasis was first observed in the Philippines in 1962 and since then it has been noted, although less frequently in Thailand, with scattered reports from ...
Description and Classification
White blood cells are described and classified in several ways:
1. By function:Defense cells; phagocytes (granulocytes, macrophages) Cells that produce ...
Leukocytosis, Granulocytosis, Neutrophilia
All three terms indicate increased circulating neutrophils (but not an increase in eosinophils or basophils). This is a very commonly encountered ...
Lymphocytosis
Increased numbers of lymphocytes in the blood may occur in infectious mononucleosis (mono), a self-limited viral infection common in young people, and acute infectious ...
This is a disorder in which RBCs – in their own serum or in other serum – clump together (agglutinate) in response to slight cooling (below 86° F it’s <30c). The clumping ...
Polycythemia
This is the opposite of anemia; the term literally means “many cells in the blood”. The blood becomes highly viscous (thick) and flows sluggishly. The condition ...
A complete blood count (CBC):
is the most widely requested and single most important lab test on blood. Many CBCs are done as routine screens – tests that provide general information ...
Optical principle: Automated systems are now based on flow-through (also called flow cytometry) opticaltechnologies that identify cells on the basis of light scatter properties broadly ...
Impedance technology. This technology was originally known as the Coulter principle. There are several variations and adaptations to the impedance principle in use today from a variety ...
The following are some of the most common anemias. They are arbitrarily grouped according to RBC color and size; other sources may group them in different ways.
1. Anemia Due to Bleeding: ...
Hemoglobin, the oxygen-carrying component of RBCs, is composed of two pairs of protein chains called globin and four smaller units called heme, which contain iron. Iron binds and releases ...
Iron is important in cellular metabolism and oxidation, the body needs only trace amounts of two
types of iron:
• Functional iron, a component of hemoglobin and myoglobin (a pigment ...
