How much blood does a human have?
What is the compositon of Blood? |
5 Liters
Cellular Elements suspended in fluid, Plasma |
|
|
What percentage of blood volume is Plasma?
|
50% - 60%
|
|
|
What is Plasma?
|
A complex solution in which blood cells are suspended. It contains sodium, chloride, amino acids, oxygen, hormones, and vitamins.
|
|
|
What percentage of plasma is water?
|
90%
|
|
|
How does the quality control in hematology differ from quality control in other lab departments?
|
Standards are not available, and is not possible with blood cells since it is a living tissue.
|
|
|
What is the only substance measured in Hematology?
|
Hemoglobin. The hematology lab must rely on commercial control solutions.
|
|
|
Define the following:
Erythrocytosis Leukocytosis Thrombocytosis |
Excess of RBC also Polychthemia
Increase of WBC above normal Abnormal increase in the number of platelets in the blood |
|
|
What are the cellular elements of blood?
|
Erythrocytes - RBC
Leukocytes - WBC Thrombocytes - Platelets |
|
|
How long does Erythrocytes live?
|
120 days.
|
|
|
Conditions that cause hematological diseases are:
|
Anemia - RBC too low
Leukemia - WBC production out of control Thrombocytopenia - Low platelet count |
|
|
Describe inherited hematological diseases:
|
Hemophilia - Bleeding problems due to the bloods inability to clot; the coagulation factor is missing.
Sickle Cell Anemia - abnormal hemoglobin function causes by structure. |
|
|
Compare accuracy and precision of manual and automated blood cell counting methods.
|
Manual Counts coefficient of 10%...Automated is 1-3%
|
|
|
Name the Five types of Leukocytes.
|
Never Let Monkeys Eat Bananas
Neutrophils 60% Lymphocytes 30% Immunity Monocytes 6% Eosinophils 3% Allergy Attack Basophils 1% Histamine |
|
|
What are GRANULOCYTES?
|
A type of white blood cell responsible for engulfing and digesting micro-organisms. Granulocytes consist of three types of phagocytic, or cell-eating, cells: basophils, eosinophils and neutrophils
|
|
|
What are AGRANULOCYTE
|
A type of white blood cell; monocytes and lymphocytes are agranulocytes
|
|
|
Define Platelet
|
Platelets are irregularly-shaped, colorless bodies that are present in blood. Their sticky surface lets them, along with other substances, form clots to stop bleeding
|
|
|
What is the function of platelets?
|
When bleeding from a wound suddenly occurs, the platelets gather at the wound and attempt to block the blood flow. The mineral calcium, vitamin K, and a protein called fibrinogen help the platelets form a clot.
|
|
|
What does plasma contain?
|
The plasma contains salts and various kinds of proteins, hormones, Sodium Na+
Potassium K+ Calcium Ca Chloride Cl- Hydrogen Carbonate HCO3- Phosphate |
|
|
What is serum
|
The clear, thin and sticky fluid portion of the blood that remains after coagulation. Serum contains no blood cells, platelets or fibrinogen
|
|
|
Plasma contains?
|
Clotting agents such as fibrinogen
|
|
|
What color tube for Serum?
What color tube plasma |
Red Top Tube
Light Blue/EDTA |
|
|
What six things are in a CBC?
|
White blood cell (WBC) Incease means Bacterial, and decrease is viral.
White blood cell differential looks at the types of white blood cells present. Red blood cell (RBC) count is a count of the actual number of red blood cells per volume of blood. Hemoglobin measures the amount of oxygen-carrying protein in the blood. Hematocrit measures the amount of space red blood cells take up in the blood. The platelet count is the number of platelets in a given volume of blood. Both increases and decreases can point to abnormal conditions of excess bleeding or clotting RBC Morphology = Anemai types |
