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.
  • 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.

Submitting Specimens

  • Forward specimens to the WSLH within 24 hours after collection.
    • NEVER hold completed blood card for hearing or heart screening results.
  • Specimens older than seven (7) days from collection date are unsatisfactory for testing, and  a repeat collection will be required.
