Study Notes

Blood Sampling Methods

  • Two main methods of obtaining blood samples: Vein punctures and Capillary punctures
  • Vein punctures method is carried out when a large volume of blood is required

Capillary Punctures Method

  • Blood can be taken from the fingertips or earlobes in the Capillary punctures method

Blood Preparation and Separation

  • Components of blood preparation and separation of plasma: blood collection, centrifugation, and plasma separation
  • The result of the blood separation process is described as a clear or transparent liquid (plasma) and a solid component (blood cells)

Microscope

  • Main function of a microscope: to magnify small objects or structures
  • A microscope typically has 3-4 objective lenses
  • Magnification power of the eyepiece (ocular lens): 10x
  • Function of the condenser in the illumination system of a microscope: to focus light onto the specimen
  • Purpose of the oil immersion objective lens: to increase the resolution and magnification power of the microscope
