Study Notes
Blood and Hematology
- Antonie Van Leeuwenhoek is described as the 'Father of Hematology' and the inventor of the microscope for the microscopic size of RBC.
Blood Composition
- The approximate total volume of blood in an average male is 5-6 liters.
- The approximate total volume of blood in an average female is 4-5 liters.
- The solid portion of blood makes up around 45% of the total volume.
Blood Properties
- The specific gravity of arterial (oxygenated) blood is 1.056-1.066.
- The specific gravity range for serum is 1.018-1.022.
- The approximate pH range of blood is 7.35-7.45.
Anticoagulants
- The component of blood that is approximately 3.5-4.5 times thicker than water is plasma.
- Ethylenediaminetetraacetic acid (EDTA) is an anticoagulant that works by binding to calcium ions, preventing blood clotting.
- EDTA is the choice for most chemistry tests.
- The ratio of blood to anticoagulant for the Standard Westergren (black top) method is 4:1.
- Sodium fluoride is an anticoagulant that inhibits glycolysis and preserves glucose.
- Sodium fluoride is used as an anticoagulant in a concentration of 2-3%.
- Heparin is an anticoagulant that works by activating antithrombin, and its optimum concentration for most chemistry tests is 10-15 units/mL.
- Citrate is an anticoagulant used in a concentration of 3.2% or 0.109M and preserves factor V and VIII.
History of Hematology
- Athanasius Kircher described a worm in the blood in 1658.
- Giulio Bizzozero described platelets in the 1800s.
Research
- 'In vivo' research refers to experiments or observations conducted within living organisms, such as animals or humans.
