Normocytic & normochromic
What morphologic change has an etiology caused by IRON DEFICIENCY?
Microcytic (small) & hypochromic (pale color)
What morphologic change has an etiology caused by COBALAMIN (B12) DEFECIENCY, FOLIC ACID DEFICIENCY
Macrocytic/ Megaloblastic (big) & normochromic
What is an example of a condition that causes NORMOCYTIC & NORMCHROMIC morphologic change?
Sickle Cell Anemia, Acute blood loss, hemolysis, Aplastic Anemia
What is an example of a condition that causes MICROCYTIC (small) & HYPOCHROMIC morphologic change?
Iron Deficiency
What is an example of a condition/conditions that cause Macrocytic (megaloblastic) & Normochromic. *Pregnant can have this.
B12 & Folic Acid Deficiency
What is another name for MICROCYTIC?
MEGALOBLASTIC meaning large in size.
A DECREASE in Hemoglobin synthesis is caused by?
IRON DEFICIENCY
This causes ________?
- Decreased Hemoglobin Synthesis
- Defective DNA Synthesis
- Decreased # of RBC precursors (think pieces to help build RBC)
Decreased RBC production
Defective DNA Synthesis is affected by what TWO deficiency’s. *Think pregnant woman
Cobalamin (Vitamin B12) deficiency & Folic acid deficiency
Blood Loss Anemia can be split into what TWO categories?
Acute and Chronic
ACUTE blood loss anemia is caused by what?
TRAUMA & Blood vessel RUPTURE
Chronic blood loss anemia is caused by what?
- Gastritis (inflammation)
- Menstrual flow
- Hemorrhoids
Trauma & Blood vessel rupture are considered ACUTE or CHRONIC blood loss anemia?
ACUTE
-Gastritis (inflammation)
-Menstrual flow
-Hemorrhoids
are considered ACUTE or CHRONIC blood loss anemia?
CHRONIC
Increased RBC destruction hemolytic anemias can be broken down into what TWO type of Hemolytic anemias?
INTRINSIC & EXTRINSIC (Aquired Hemolytic anemia)
- Abnormal hemoglobin (Hb S–sickle cell anemia)
- Enzyme deficiency (G6PD: glucose-6-phosphate dehydrogenase)
- Membrane abnormalities (paroxysmal nocturnal hemoglobinuria, hereditary spherocytosis
this is INTRINSIC or EXTRINSIC (Acquired Hemolytic Anemia)
INTRINSIC
- Physical trauma (prosthetic heart valves, extracorporeal circulation)
- Antibodies (isoimmune and autoimmune)
- Infectious agents and toxins
this is INTRINSIC or EXTRINSIC (Acquired Hemolytic Anemia)
EXTRINSIC
