    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.
