Hematology and Anemias Flashcards
hypoproliferation
decreased production of RBC
OR produced defective RBC
hemolysis
increased destruction of RBC
hemorrhage
blood loss produces anemia
erythropoeitin (Epo)
produced in the kidney which senses hypoxia
common symptoms of anemia are
weakness and fatigue
anemia due to decreased O2 transport presents with
fatigue
dsypnea
angina
anemia due to decreased blood volume presents with
pallor postural hypotension syncope headache tinnitus (ringing in the ears)
anemia due to decreased cardiac output presents with
tachycardia
systolic ejection (heart murmur)
lightheaded
anemia due to hemolysis of RBC presents with
jaundice
splenomegaly
3 tests that indicate iron deficiency anemia
- serum iron
- total binding iron capacity (TIBC)
- ferritin
serum iron normal value
60-170 mcg/dcl
TIBC normal value
measurement of transferrin
240-450 mcg/dcl
ferritin normal value
measurement of amount of ferritin in blood
male 12-300 ng/ml
female 12-150 ng/ml
site of absorption of iron
duodenum and upper jejunum
site of absorption of B12
terminal ileum and stored in liver
pernicious anemia
lack of intrinsic factor of autoimmune destruction of parietal cells
2 tests to indicate B12 anemia
- CBC
2. serum B12
normal serum B12 reading
160-950 pg/dl
site of absorption of folate/folic acid
proximal jejunum
normal range of folate
2.7-17.0 ng/ml
test to indicate folate anemia
CBC (macrocytic anemia)
chronic GI bleed would have
decreased serum iron
decreased ferritin
Heavy menstrual bleeding would have
decreased serum iron
decreased ferritin
malabsorption of iron would have
decreased serum iron
insufficient dietary iron would have
low serum iron
pregnancy would have
low serum iron
high TIBC
anemia of chronic disease would have
low serum iron
low TIBC
high ferritin
iron deficiency anemia would have
decreased serum iron
increased TIBC
decreased ferritin
hemolytic anemias would have
high serum iron
low TIBC (free iron is binding to transferrin)
high ferritin
hemosiderosis/hemochromatosis would have
high serum iron
high TIBC
high ferritin
hepatic necrosis would have
high serum iron
hepatitis and cirrhosis would have
high serum iron
low TIBC
high ferritin
vitamin B deficiency would have
high serum iron
low TIBC
iron poisoning would have
high serum iron
multiple blood transfusions would have
high serum iron
sickle cell anemia would have
high serum iron
low TIBC
hypoproteinemia would have
low TIBC
Polycythemia vera would have
high TIBC
Contraceptives (OCPs) could cause
high TIBC
low serum B12
low serum folate
Hodgkins lymphoma would have
high ferritin
megaloblastic (macrocytic) anemia would have
high ferritin
any inflammatory disorder would have
high ferritin
sideroblastic anemai would have
body produces ringed sideroblasts, instead of healthy RBC
high serum iron
normal TIBC
high ferritin
vitamin B12 is obtained by the body through
dietary sources (meats, cheese, milk and eggs)
folate is obtained by the body through
dietary sources (leafy greens, liver and eggs)
iron deficiency anemia is a
microcytic anemia
anemia of chronic disease can be
microcytic or normoocytic
thalassemia is a
microcytic anemia
sideroblastic anemia is a
microcytic anemia
lead poisoning is a
microcytic anemia
renal failure causes
normocytic anemia
myelodysplastic syndrome causes
normocytic and macrocytic anemia
endocrinopathy causes
normocytic anemia
aplastic anemia is a
normocytic anemia
RBC aplasia is a
normocytic anemia
myelofibrosis causes
normocytic anemia
myelophthisis causes
normocytic anemia
hemolytic anemia with low retic count can be
normocytic or macrocytic anemia
mixed micro and macrocytic anemia can present as
normocytic anemia
multiple myeloma causes
normocytic anemia
pernicious anemia is a
macrocytic anemia
specific type of vitamin B deficiency where by parietal cells of the stomach are killed and no longer secrete instrinsic factor which is needed by the ileum to absorb vitamin B
folate deficiency is a
macrocytic anemia
alcohol and drugs causes
macrocytic anemia
hypothyroidism causes
macrocytic anemia
liver disease causes
macrocytic anemia
