Term
what is two things that a pleuipotent stem cell does?
Definition
1. replicates and makes more pleripotent stem cells
2. morph into a myeloid stem cell or a lymphoid stem cell.
Term
What does shift to the left mean?
Definition
more immature cells
Term
What does normal bone marrow look like under microscope?
Definition
heterogenous mix of cells.
Term
erythrocytosis
Definition
too manny RBCs
Term
Anemia
Definition
too few RBCs
Term
what is polycythemia vera? and what does it cause?
Definition
overproduction of RBCS. Causes erythrocytosis.

Polycythemia is a pre leukemic condition.
Term
What causes secondary polycythemia? and what does this lead to?
Definition
caused by lung disease. body is in chronic state of hypoxia which causes increased RBC production leading to erythrocytosis
Term
What causes relative polycythemia? and what is it?
Definition
caused by dehydration or spurious(means we dont know). it is where RBCs #s are normal but [plasma}is decreased.
Term
what is a reticulocyte?
Definition
earliest immature RBCs in peripherial blood.
Term
What are three causes of jaundice? only ones he named in class
Definition
hemolysis, liver or gb disease
Term
What is CBC? what does it consist of?
Definition
Complete blood count
HCT, Hgb, RBC, RBC indices, WBC, WBC type (differential), platelet count and blood smear
Term
what are the RBC indices?
Definition
MCV, MCH, MCHC
Term
What is MCV?
Definition
average size of RBCs
Term
MCH
Definition
hemoglobin amount per RBC
Term
What should you think of if MCV is increased?
Definition
macrosidic anemia
Term
What is MCHC?
Definition
amount of Hgb relative to size of the cell.
Term
What is hematocrit (HCT)?
Definition
% RBC/ blood volume
Term
what does microsidic hypochromic anemia mean?
Definition
small RBCs that are poorly hemoglobinized. due to iron def. or thallasemia (80-90% of cases)
Term
What are two relative causes of anemia?
Definition
hypersplenism and increased plasma volume (common in pregnancy)
Term
thrombocytopenia?
Definition
no platelets/ low platelets
Term
What causes meagaloblastic/hypersegmentation?
Definition
folate/ B12 def.
Term
Poikilocytosis
Definition
All cells are different sizes (abnormal)
