1

CBC-Hemoglobin

12-18g/dL
Indication of oxygen transport capacity of blood

2

CBC- Hematocrit

38-54% Percent of blood composed of erythrocytes- 3x HGB

3

CBC- MCV

Average volume of RBC
Macrocytic- large cells- due to B12 or folic acid deficiency
Microcytic- small cells- due to iron deficiency

4

CBC- Platelet Count

150,000-450,000
Number of platelets in blood sample.
Thrombocytopenia-
viral illness, warfarin, petechiae
Thrmobocythemia- Risk of DVT, PE- estrogen, smoking, sedentary

5

CBC- Mean Cell Hemoglobin (MCH)

27-33 picogram
Amount of hemoglobin in 1 RBC- used with MCHC to determine iron deficiency

6

CBC- Mean cell hemoglobin concentration (MCHC)

33-37 g/dL
Hypochromic indicates iron deficiency

7

CBC- Red cell distribution width

Distribution of size of RBCs- wide indicates varied cell sizes- mixed anemia or thalassemia

8

CBC- White blood cell count

500-10,000mm2
Number of leukocytes in volume of blood- order differential to determine types of WBCs

9

CBC- WBC differential

PMNs, Band neutrophils- Acute infection,
lymphocytes- viral infection,
monocytes- chronic infection,
eosinophils- allergy/worms basophils- chronic inflammation.

10

Normocytic anemia

Hgb &Hct-low, MCV- normal

11

Microcytic anemia

Hgb &Hct-low, MCV & MCHC- decreased

12

Macrocytic anemia

Hgb &Hct-low, MCV increased

13

Polycythemia

Hgb & Hct- high

14

Leukocytosis

WBC increased- differential indicates type and reason

15

Leukopenia

WBC decreased- differential leads to reason

16

Thrombocytosis

Platelets >400,000- risk of excessive clotting

17

Thrombopenia

Low platelet- risk of uncontrolled bleeding

18

CBC- left shift

Increase in number of band (immature) cells. Indicates infection, leukemia, myeloprolifereative disorders, myelofibrosis, hemorrhage

19

Fresh whole blood

All blood components- Indicated for hemorrhage >25% blood loss, cardiac surgery, emergencies

20

Packed RBC

RBCs with small amt plasma and variable leukocytes- indicated to raise hematocrit, increase O2 carrying capacity

21

Leukocyte poor blood

Decreased leukocyte levels- to reduce risk of agglutination rxn

22

Frozen packed RBC

Stored for 10 years, preserve rare blood types- pts with severe retains to plasma protein

23

Autologus packed RBC

Patients own blood stored for future use- elective surgery, stored 35 days before freezing

24

Hemolytic transfusion reaction-

Mismatch of ABO blood typing- fever, chills, HA, hypotension. Prevention- hydration & diuresis

25

Anaphylactic reaction

IgE mediated response to incompatible blood- shock, vasodilation. T with epi, airway mgmt, steroids

26

Bone marrow biopsy

Diagnosis of leukemias- unexplained anemia, thrombocytopenia, leukopenia

27

Lymph node biopsy

Diagnosis of lymphoma based on cellular morphology

28

Total Iron Binding Capacity

Measures iron bound to transferrin- Increased in iron deficiency anemia

29

Serum Ferritin

Indirect measure of iron stores- markedly reduced in iron deficiency anemia

30

CBC

Low Hgb & Hct- indicates which type and deficiencies. Initial test
