new born
T/F: neutrophils and lymphocyte counts are different for adults and children (<5yo)
TRUE
neutrophils 50-70%
adult
neutrophils 20-40%
child
lymphocytes 20-40%
adult
lymphocytes 50-70%
child
____ are used to diagnose or evaluate individuals with inflammation, infection, neoplasia, or immunosuppression
WBC
____ predominate until age 4-5 then ___ predominate and adult values are present
lymphocytes -> neutrophils
-____ or -______ is a condition of or increase in
- osis
- philia
-____ is a condition of decrease
-penia
WBC count is increased, usually indicates inflammation/bacterial infection
leukocytosis
WBC count is decreased; seen in marrow suppression, overwhelming infection, auto immune, viral syndromes (low normal)
leukopenia
bacterial infection or an inflammatory response
neutrophilia
viral infections: ALC lymph count normal, but the total WBC count shows leukopenia due to decreased granulocytes
lymphocytosis
SBE, disseminated TB, lymphoma or leukemia, typhoid
monocytosis
acute allergic attacks, certain skin conditions: permphagus or psoriasis; scarlet fever and brucellosis
eosinophilia
CML, myeloproliferative diz
basophila
non-leukemic WBC count of >50000 or a differential count of more than 5% metamyelocytes or earlier cells; a more severe ordinary non neoplastic granulocytic reaction
leukemoid reaction
may develop at any stage of cell maturation and is named accordingly; the more immature the predominant cell, the worse the prognosis
leukemia
has >25% blast forms present in the peripheral blood
acute leukemia
True/False: Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia occur about equally but in differing groups
TRUE
in child hood before the age of 10
Acute Lymphoblastic Leukemia
ALL
mostly in adults over 50yo
Acute Myeloid Leukemia
AML
has more mature forms and a better prognosis
chronic leukemia
makes up about 30% of all leukemia; usually occurs after 50yo, men 2:1, elevated WBC majority of time
chronic lymphoblastic leukemia
seen at 20-50 years of age, 20% of all leukemia; myelocytes or metamyelocytes are present, associated with the presence of philadelphia chromosome
chronic myeloid leukemia
is an increase in the blood cell mass; there are three types
polycythemia
three types of polycythemia
vera
relative
secondary
where all cells are increased (RBC, WBC, platelets)
vera polycythemia
caused by dehydration
relative polycythemia
caused by hypoxia
secondary polycythemia
