General Diagnosis 7 Flashcards
RBC
absolute number of circulating RBCs per unit volume of blood
normal levels of RBC
4-6 million/cm3
RBC increased
primary polycythemia vera
relative/secondary (high altitude)
RBC decreased
anemia
Hb
direct measure of weight of hemoglobin/unit volume of blood
normal levels of Hb
15 gm%
Hb increased
dehydration
loss of blood fluid volume
polycythemia vera
Hb decreased
anemia
Hct
packed cell volume
ratio of the volume of RBCs to that of whole blood
Hct normal
42 +/- 5%
increased Hct
dehydration
polycythemia vera
decreased Hct
anemia
MCV
mean corpuscular volume
calculated measure of the size of the average circulating RBC
normal MCV
90
increased MCV
macrocytic anemia
decreased MCV
microcytic anemia
MCHC
mean corpuscular Hb concentration
average concentration of Hb in a given volume of packed cells
normal MCHC
33
increased MCHC
macrocytic anemia
decreased MCHC
microcytic anemia
platelets
thrombocytes
absolute quantification of circulating thrombocytes/volume
normal platelets/thrombocytes
200,000-350,000mm3
increased platelets/thrombocytes
polycythemia
trauma
blood loss
decreased platelets/thrombocytes
anemia
extenive burns or thrombocytopenia
WBC
absolute quantification of total circul WBC/unit of blood
normal WBC
5-10,000mm3
increased WBC
acute infetion
inflammation
leukemia (over 50,000)
