Study Notes
Blood Typing
- The basis of blood typing is the presence or absence of specific antigens on the surface of red blood cells (RBCs).
Rh Blood Type
- The Rh+ designation indicates the presence of the Rh antigen on the surface of RBCs.
ABO Blood Group System
- The ABO blood group system is based on the presence or absence of A or B antigens on the surface of RBCs.
Anemia Classification
- Anemia is classified based on the size and color of RBCs, as well as the underlying cause of the condition.
Consequences of Anemia
- Severe anemia can lead to inadequate oxygen delivery to tissues, resulting in organ failure and even death.
Characteristics of Microcytic, Hypochromic RBCs
- Microcytic, hypochromic RBCs are characterized by being small in size and having a low hemoglobin concentration.
Pernicious Anemia
- Pernicious anemia is a condition characterized by a deficiency in vitamin B12 absorption due to a lack of intrinsic factor.
Symptoms of Iron Deficiency Anemia
- A common symptom of iron deficiency anemia is fatigue.
Sickle Cell Anemia
- The basic problem in sickle cell anemia is the abnormal shape and structure of hemoglobin, leading to rigid and sickle-shaped RBCs.
Hemolytic Anemia
- Hemolytic anemia is a type of anemia that results from excessive destruction of RBCs.
Learn the fundamentals of blood typing, including the ABO and Rh systems, antigens in erythrocytes, causes of blood type variations, and classification methods based on changes in erythrocytes.
