| Question | Answer |
|---|---|
| Erythropoiesis= erythrocytes = | Red blood cells |
| Leukopoises= leukocyte= | White blood cells |
| Thrombopoiesis= thrombocytes= | Platelets |
| What should you do before drawing blood | Figure out what is needed, determine equipment & supplies needed, determine which blood vessel is best, make sure Pt was fasted |
| Draw blood before medical | Tx (treatment) |
| Best vessel to draw blood is | Jugular |
| Collection equipment | Needle & syringe -> biggest needle possible and vacutainer |
| Draw enough blood for | 3 tests |
| Whole blood | Need tube with anticoagulant |
| Invert tubes, | Never shake |
| Plasma | Spun down green top tube |
| Serum | Blood clots and then spun down |
| Check tests before picking | Anticoagulants |
| If you do not use blood within 1 hour you should | Refrigerate |
| If blood has been refrigerated you need to | Bring back to room temperature before use |
| Don't freeze blood because | Lysing cells (break apart) |
| Sample volume | Well hydrated Pt will make half the amount of plasma/serum drawn up |
| CBC | Complete blood count |
| Best to do a manual and automated | CBC |
| CBC includes | Total Rbc's PCV, PLASMA PROTEIN CONCENTRATION (TP), TOTAL WBC, BLOOD FILM EXAM, DIFFERENTIAL WBC's, RDC (Red cell distribution width) & WBC morphology & PlT |
| Read PVC 1st then | Break above Buffy coat to get plasma |
| Plasma should be | Clear to light yellow |
| If plasma is pink and cloudy the animal | Just ate |
| Penia | Decrease number of cells in the blood |
| Philia/cytosis | Increased number of cells in the blood |
| Left shift | Increases number of immature neutrophils in the blood |
| Neoplastic cells in blood or marrow is | Leukemia |
| Leukemoid response | Condition that can be mistaken for leukemia |
| Neutrophil | Irregular nucleus, irregular & elongated, 3-5 lobes |
| Band neutrophil | Immature neutrophil, looks like a horseshoe & not common to see in normal animals |
| Lymphocyte | Large nucleus, light blue cytoplasm, looks like eyes, a granular |
| Monocytes | Largest wbc's, variably shaped nuclei, vacuoles, agranular |
| Eosinophil | Nucleus similar to neutrophils, granular, commonly, stain red to pink, much lighter than the nucleus. Triggered by histamine released from mast cells; allergies |
| Basophils | Nucleus is similar to monocytes, granular, granules stain darker than the than the nucleus dark blue - black; triggered by the release of eosinophils and allergies |
