septicemia
having bacteria in blood stream; commonly referred to as blood poisoning
anemia
reduction in number of red blood cells (RBCs) or amount of hemoglobin in blood
aplastic anemia
severe form of anemia that develops as consequence of loss of functioning red bone marrow
erythrocytosis
too many red cells
erythropenia
too few red cells
hemolytic anemia
anemia that develops as result of excessive loss of erythrocytes

anemia resulting from having insufficient hemoglobin in erythrocytes
iron-deficiency anemia
anemia resulting from having insufficient iron to manufacture hemoglobin

blood culture and sensitivity (C&S)
sample of blood is incubated in laboratory to check for bacterial growth
complete blood count (CBC)
blood test consisting of five tests; red blood cell count (RBC), white blood count (WBC), hemoglobin (Hg), hematocrit (Hct), and white blood cell differential
erythrocyte sedimentation rate (ESR)
blood test to determine rate at which mature red blood cells settle out of blood after addition of anticoagulant
hematocrit
blood test to measure volume of red blood cells (erythrocytes) within total volume of blood
hemoglobin
