What type of immunity are NK cells

non-specific immunity, recognize NON-self

4

Bandemia

Left shift = high number of immature WBC

5

What do you see with left shifts and what does it indicate?

increase segments and bands on CBC
serious infections (bacterial)

6

Aplastic anemia

bone marrow suppressed , no production

7

Leukemoid Rxn is define by what lab result?

leukocytosis >50,000

8

What do you have to rule out with leukocytosis of >50,000?

chronic myeloid leukemia

9

What is leukemoid Rxn caused by?

infection

10

normal WBC count

4,400 - 11,000 cells/microL

11

WBC count for severe neutropenia

<500 cells/microL

12

anemia

deficiency in O2 carrying capacity of blood from low RBC or HGB defect or defect in iron carrying capacity

13

Hematocrit

% of RBC in blood

14

normal HGB for adult male and female

men: 13.8-18 g/dL
women: 12.1 - 15.1 g/dL

15

What lab results to look at in anemia?

HGB
HCT
RBC count

16

Hypochromic, microcytic anemia caused by

HGB alpha/beta chain defect: thalassemia
heme porphyrin ring defect: porphyria
iron availability: IRON DEFICIENCY ANEMIA BIGGEST CAUSE

17

MCV, MCHC, MCH lab results for hypochromic, microcytic anemia

MCV: <80 fL
MCHC: <32 fL
MCH: <27 fL

18

normal MCV

80-100 fL

19

Ratio of HCT to HGB

HCT always 3x HGB

20

MCV formula

(10 x HCT%) / RBC count

Menstrual bleed
Pregnancy + Lactation
GI bleed

23

Gold standard test for iron deficiency

serum ferritin

24

Sideroblastic anemia

bone marrow produces ringed sideroblast instead of healthy RBC (ring of iron deposits)
hyperchromic, microcytic

25

What to see on smear for sideroblastic anemia

hyperchromic, microcytic, ringed sideroblasts

26

Treatment for sideroblastic anemia

controlling symptoms and prevent organ damage from iron overload
Chelation therapy to remove iron

27

Thalassemia

abnormal alpha, beta HGB
target cells

28

What to see on smear for Thalassemia

hypochromic, microcytic, target cells

29
