Specimen Handling

After blood has been applied to the filter paper, proceed as follows:

  • Allow blood-soaked collection card to dry in a horizontal (flat) position. Example image and drying rack example image
  • Suspend blood-soaked area of collection card such that air can dry both sides of the card equally.
    NOTE: Be sure the attached cover slip doesn’t come into contact with the blood until completely dry. Do not allow the blood-soaked portion of the collection card to come into contact with another surface (desktop, absorbent paper, etc.).
  • Allow blood to air dry at room temperature for a minimum of three (3) hours.
    NOTE: Do not use artificial heat (lamps, incubators, etc.) to dry the specimens.
  • Evaluate specimen for acceptability. See How to Collect a Blood Specimen and sample images at Satisfactory and Unsatisfactory Collection Card.
  • Replace the cover slip over the blood when completely dry.
