Hematology & Coag.
Hematology & Coagulation Studies
Term | Definition |
---|---|
ESR | increased in an inflammatory disease like rheumatoid arthritis |
eosinophil | WBCs would be elevated during an allergic reaction |
oxygen-carrying capacity | determines the hemoglobin content of the RBCs |
hematocrit | volume of packed RBCs |
120 days | the RBC remains functional in the blood stream without a nucleus |
RBCs | most plentiful cellular component found in the blood |
how many different WBCs are there? | 5 |
thrombocyte | main function hemostasis and providing a surface for clotting proteins |
general causes of anemia | blood loss, insufficient production of RBCs and excessive destruction of RBCs |
CBC consists of | WBC count, RBC count, Platelet estimate, WBC differential, hemoglobin, hematocrit and RBC indices |
middle layer of a centrifuged blood sample, separtaed into 3 layers | WBC and platelets |
INR | ratio that compares results to ensure consistency from one lab to another |
lymphocyte | second most plentiful WBC in a differential count |
RBC indices | indicators of anemia |
patient with COPD and CHF may be more likely to have | increased hemoglobin |
sickle cell anemia | inherited disorder caused by the presence of hemoglobin S |
patient with elevated PT or INR are in danger of | internal bleeding |
pancytopenia | decrease in all blood cell types |
leukopenia | low number of total WBCs also referred to as leukocytopenia |
pernicious anemia | decreased number of RBCs caused by a lack of vitamin B12 |
sickle cell anemia | inherited disorder which causes a sickle-shaped RBC, interfering with the ability of the cell to carry oxygen |
leukocytosis | increase in. the total number of WBCs |
thrombocytosis | an overproduction of platelets |
hemolytic anemia | inherited or acquired disorder that results in the destruction of the RBCs |
aplastic anemia | anemia caused by bone marrow disorders that inhibit or decrease the productions of RBCs |
erythrocytosis | abnormal increase in the number of RBCs |
leukemia | malignant cancer of WBCs in which the bone marrow creates abnormal and dysfunctional WBCs |
monocyte | large, irregularly shaped nucleus |
lymphocyte | small count of cytoplasm surrounding a round to oval-shaped nuleus |
basophil | coarse purplish-black cytoplasmic granules |
neutrophil | pinkish-purple fine granules in the cytoplasm |
eosinophil | coarse organe-red granules in the cytoplasm |
PT | 10-13 seconds |
aPTT | 25-40 seconds |
INR | 0.8-1.1 |
