|
Characteristics of neutrophils? |
Numerous Nuclei Slightly larger than RBC Fine, light granules |
|
Characteristics of Eosinophils? |
2 nuclei like Eyeballs Prevalent, peach/pink granules |
|
Characteristics of basophils? |
Dark, almost black granules congregated toward outer edge Big blob, barely visible (or not visible) nucleus |
|
Characteristics of lymphocytes? |
About the same size as RBC Huge nucleus that takes up the majority of the cell Cytoplasm is light blue and free of granules |
|
Characteristics of Monocytes? |
Massive C or bean shaped nucleus Cytoplasm is blue and free of granules, with more showing than in lymphocytes |
|
Differential WBC Count |
100 white blood cells are counted, with types of cells tallied |
|
Leukopenia |
Lower than normal number of WBC |
|
Leukocytosis |
Abnormally high WBC count |
|
Sickle cell anemia |
A condition that causes abnormal hemoglobin formation. Erythrocytes present as half moon shaped cells |
|
|
Hematocrit Centrifuge |
|
|
Rh Typing Box |
|
|
Tallquist Scale Booklet |
|
|
Seal Eaze |
|
|
Non heparinized capillary tube |
|
|
Tallquist paper |
|
|
Hematocrit Reader |
|
|
Heparinized capillary tube Aka hematocrit tube |
|
Hematocrit |
Aka volume of packed cells, packed cell volume The relative percentage of red blood cells in a given volume of whole blood |
|
Normal hematocrit readings |
Adult females: 38%-47% Adult males: 40%-54% |
|
Polycythemia |
Overproduction of RBC |
|
Anemia |
Decreased ability of the blood to transport O2 Sometimes caused by lower than normal number of RBC |
|
Heparin |
Anticoagulation Makes up the red line on the hematocrit tube |
|
Procedure for hematocrit test |
1. Place capillary tube in vertical slot so that blue clay is lined up with the small red line 2. Slide the vertical slot horizontally until the top of the plasma lines up the the 100% line 3. Move the diagonal piece so that the black line runs along the upper edge of the RBC 4. Read your percentage at the top |
|
Procedure for hemoglobin estimate test |
1. Gently roll your bleeding finger over tallquist paper 2. Compare the coloration with the Tallquist scale by placing the paper under the holes in the Tallquist scale booklet |
|
Hemoglobin |
The O2 and CO2 carrying compounds in RBC |
|
Iron deficiency anemia |
Insufficient iron which results in low hemoglobin levels |
|
Hemochromatosis |
The body stores too much iron |
|
Normal hemoglobin ranges |
Females: 12-16g/100ml Males: 14-18g/100ml |
|
Coagulation |
Clotting |
|
Hemostasis |
The process of stopping the flow of blood |
|
Fibrin |
Thread-like protein fibers involved in the clotting process |
|
Coagulation Time Procedure |
1. Load nonheparinized capillary tube to about 1/2 full 2. After about 8 minutes, take the tube between your thumb and forefinger and gently break it in half 3. Slowly pull the ends apart to view the insoluble fibrin strands |
|
Normal platelet range |
Adults: 250,000 - 400,000 platelets per cc |
|
Thrombocytosis |
Excessive number of platelets in blood |
|
Thrombocytopenia |
Greatly reduced platelet count |
|
Vitamin and ion necessary for coagulation |
Vitamin K and calcium |
|
The most common way to type blood? |
ABO blood typing system |
|
Antigen |
A glycoprotein that acts as a surface marker on red blood cells |
|
Antibody |
Aka agglutinin Protein secreted by lymphocytes involved in the immune response |
|
Agglutination |
Clumping of RBC caused by specific antibody/antigen reaction |
|
Hemolysis |
The destruction or rupturing of RBC |
|
Blood type A |
Antigen A is present on the red blood cells Anti B (antibody) is in the plasma |
|
Blood type B |
Antigen B is present on the RBC Anti A (antibody) is present in the plasma |
|
Blood type AB |
Antigens A and B are present on the RBC No antibodies are present in the plasma |
|
Blood type O |
No antigens are present on the RBC Anti A and Anti B (antibodies) are present in the plasma |
|
Rh Factor |
D Antigen, present on RBC Determines if blood type is + or - |
|
Antiserums used to type blood |
Anti-A serum: Anti-A antibodies Anti-B serum: Anti-B antibodies Anti-Rh serum: Anti-D antibodies (an Rh Typing box may be necessary to see this agglutination) |
