What type of centrifuge is "swinging arm"? The specimen cups hang vertically at rest and swing out horizontally when spinning.
What type of centrifuge has tubes held at a fixed angle? Can only hold one tube size and must be balanced.
Angled Centrifuge Head
What is another name for the Total Solids Meter? Used to measure the refractive index of a solution (tells you the concentration of solid material in a liquid).
What measures the amount of light transmitted through a solution? The degree of color change is proportional to the solution's concentration.
_ machines use reagent impregnated strips, slides, or pads. The color change is read on the pad, strip, or slide.
What machines count the number of red blood cells, white blood cells & platelets?
What machine has the cells pass through an aperture that measures the size of the cells & then counts them as certain cell types based on that size?
What does blood do?
1. Carries oxygen to tissue
2. Carries carbon dioxide away from tissue
3. Carries nutrients to tissue
The liquid portion of the blood that the cells are suspended in. It makes up 45 - 78% of blood.
What is blood that has not clotted? It is either in circulation or it has an anticoagulant added.
What anticoagulant is used when chemical testing is performed? It is not good for whole blood.
What anticoagulant is used when hematologic studies are done because it does not interfere with morphology?
_ is plasma minus fibrinogen. To get this sample you need to allow the blood to clot & then centrifuge it down.
_ plasma protein levels indicate overhydration, renal disease, gastrointestinal problems, or a diseased liver.
What is stain one? It fixes the slide and the slide should stay in this stain for at least 5 minutes.
What color is stain two? It stains the RBCs. Dip the slide 25 times in stain two, allowing it to sit in the stain for 1 second between dips.
What color is stain three? It stains the nuclei of the cells. Dip the slide 10 times, but don't let the slide sit in the stain between dips.
_ erythrocytes have a distinct area of central pallor. That means that when you stain them, the very center of the cell doesn't take up stain.
The _ nucleus is horse shoe shaped and lobulated. They contain enzymes that destroy bacteria and viruses. It is a granulocyte.
_ are associated with allergic and parasitic type reactions. They have red/light pink granules.
_ are the largest WBCs. The cytoplasm stains gray & contains vacuoles. They ingest or eat cellular debris in the body. It is a agranulocyte.
_ are the second most common WBC. The cytoplasm is very light blue and the nucleus is large and round. They are associated with antibody production. It is a agranulocyte.
What test contains the following components: total RBC count, PCV, plasma protein concentration, total WBC count, blood film examination (WBC differential, RBC & WBC morphology, platelet estimation), hemoglobin concentrations, erythrocyte indices & a reticulocyte count when the patient is anemic?
Complete Blood Count (CBC)
What does MCV stand for? It is the measure of the average size of the erythrocytes.
Mean Corpuscular Volume
A condition that can be mistaken for leukemia. Characterized by marked leukocytosis & is usually the result of an inflammatory condition.
What WBC has pale pink cytoplasm with granules and a 3 - 5 lobe nucleus? Most numerous WBCs.
What WBC has light blue cytoplasm and may contain pinkish-purple granules? 2nd most common WBC. Associated with antibody production.
What WBC has blue-gray cytoplasm, vacuoles and pink granules? Eat cellular debris. Largest WBC.
What WBC has a segmented nucleus & contains blue granules in the cytoplasm? Very rare cells associated with allergic reactions.
What WBC has a segmented nucleus & contains red granules in the cytoplasm? Associated with allergic reactions. Usually only 1 or 2 found.
Grouping of RBCs in stacks. Normal in equine & feline blood. Artifact in refrigerated blood.
How to differentiate agglutination from rouleaux: Add a drop of saline to the slide. If _, the cells will disperse.
Large RBCs that stain a different color (usually bluish to bluish-red). Patients with altered lipid metabolism (liver disease).
