| what does the blood do | carries oxygen and nutrients to the body |
| what are the two blood layers | liquid cellular |
| what are the differences between serum and plasma | serum does not have any clotting factors plasma has clotting factors |
| define anemia | abnormal blood count |
| define penia | abnormally low count |
| define philla | abnormally high count |
| where is blood made | in the bone marrow |
| what are the three types of blood cells | red blood cells / erythrocytes white blood cells / leukocytes platelets / thrombocytes |
| what are three responsibilities of the restrainer | restraint present and stabilize the site occlude the vein for blood draw |
| what are the three points for canine venipuncture sites | jugular cephalic lateral saphenous |
| where is the jugular site | neck |
| where is the cephalic site | front of front leg |
| where is the lateral saphenous site | outside upper rear leg (K9 only) |
| where is the medial saphenous site | inside rear leg (feline only) |
| what does the tiger or serum separator top tube have in it | paraffin wax |
| what does the purple top tube have in it | EDTA |
| what does the blue top tube have in it | sodium, potassium citrate |
| what is the tiger top tube or SST used for | separates cells from serum used for blood chemistries |
| what is the purple top tube used for | complete blood counts platelet count |
| what is the blue top tube used for | coagulation assay |
| what are the 2 special instructions for the blue top tube | tube must be filled too yellow line you get one stick to get it |
| what does a hematocrit test measure | packed cell volume |
| how is packed cell volume measured | in % |
| what does packed cell volume test tell you | determines the percent of RBC in circulation |
| what is a normal PCV level | 45% |
| what is the normal range of total protein in cats and dogs | 6-8 g/dl |
| if you have an increased total protein level what might that tell you | extreme dehydration |
| what would a decreased total protein tell you | starvation |
| what is hemoglobin | protein and iron |

| which of the WBC have granulocytes (hint phil's) | neutrophil eosinophil basophil |
| what is a band cell | an immature neutrophil |
| why might you see band cells | anemia |
| if you have greater then 5% band cells what is that called | left shift |
| what is a venipuncture | puncturing a vein or vessel |
| what would a white plasma/serum tell us | too much fat in the diet |
| what would a yellow serum/plasma tell us | icteric (signs of liver disease) |
| what would a red serum/plasma tell us | traumatized draw multiple sticks |
| what is an ELISA / snap test for | testing for antigens |
| what is a left shift | when we see more than 5% band cells |
| which organ is total bilirubin associated with | liver |
| if your sample is spun down and top part is white what type of sample do you have | lipemic / |
| if your sample is spun down and top part is yellow what type of sample do you have | icteric |
| if your sample is spun down and top part is red what type of sample do you have | hemolized |
