- Normal MCH is
- 26-35
- Schilling Test
- used to dx pernicious anemia- missing intrinsic factor in gut, urine test, 24-48 hours, evaluates Vb12 absorption, radioactive VB12 given orally, nonradioactive VB12 given IM, have to sign consent for this test
- If MCV is low then the cells are
- microcytic (small)
- CBC diagnostic test
- RBC, hematocrit/Hgb, WBC (differentail count), MCV Mean corpuscular vol.
- Reticulocyte count
- 0.5-1.5% (if high- increase production of RBC)
- MCHC is
- mean corpuscular hemoglobin concentration
- Transferrin is what
- a protein which transports iron from GI tract
- Serum Ferritin measures
- free iron in blood (10g or lower- inadequate iron stores)
- Erythropoesis
- Trigger for control: kidney produces the RBC growth factor (erythropoietin) at the rate of destruction ( hypoxia)
- Components of Blood
- RBC, WBC and Platelets
- 1st sign of Hypoxia is
- restlessness (assess patient O2, vital signs and check for bleeding (bruising)
- Normal MCHC is
- 31-37
- Three main plasma proteins(p. 870-871)
- Albumin, Gobulins and Fibrinogen
- TIBC
- is a better test, if elevated, deficienccy of serun (iron in blood) and stored iron
- If MCV is elevated then the cells are
- macrocytic (large)
- MCH is
- mean corpuscular Hgb avg. amt. of Hgb in one RBC
