Blood Types
Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.
Blood Transfusion
Blood types become very important when a blood transfusion is necessary. In a blood transfusion, a patient must receive a blood type that is compatible with his or her own blood type - that is, the donated blood must be accepted by the patient's own blood. If the blood types are not compatible, red blood cells will clump together, making clots that can block blood vessels and cause death.

Type O- blood is considered the "universal donor" because it can be donated to people of any blood type. Type AB+ blood is considered the "universal recipient" because people with this type can receive any blood type.

Medical Laboratory
    A medical laboratory or clinical laboratory is a lab that tests clinical specimens in order to determine information about the health of a patient as related to the diagnosis, treatment, and prevention of disease. The credibility of medical laboratories is important to the health and safety of the patients relying on the testing services provided by these labs. There is an international standard in use today for the accreditation of medical laboratories. This standard is ISO 15189 - Medical laboratories particular requirements for quality and competence.
    Laboratory medicine is mainly divided into four areas of analysis; anatomic pathology, clinical microbiology which deals with the study of microorganisms including bacteria, viruses, fungi and parasites, clinical biochemistry which deals with the analysis of bodily fluids, and hematology which is concerned with the study of blood, the blood-forming organs, and blood diseases.
