Decreased oxygen-carrying capacity from fewer RBCs or less hemoglobin leading to tissue hypoxia What hormone increases RBC production in response to low oxygen? Erythropoietin released by the kidneys Low oxygen triggers what kidney-to-bone-marrow pathway? Hypoxia stimulates kidneys to release EPO which increases RBC production What is required for normal erythropoiesis? Oxygen erythropoietin iron vitamin B12 folate and protein What does a low reticulocyte count indicate? Decreased RBC production (bone marrow problem) What does a high reticulocyte count indicate? RBC loss or destruction MCV less than 80 fL indicates what type of anemia? Microcytic anemia MCV 80-100 fL indicates what type of anemia? Normocytic anemia MCV greater than 100 fL indicates what type of anemia? Macrocytic anemia Microcytic anemia usually reflects a problem with what? Iron or hemoglobin synthesis Macrocytic anemia usually reflects a problem with what? DNA synthesis often due to B12 or folate deficiency What does MCHC measure? Average hemoglobin concentration inside RBCs
