To avoid unnecessary aliquoting/transferring of sample to minimize volume loss, low-volume samples ocular specimens can be left in a properly packaged syringe.

  • Remove all sharps
  • Place a screw-on cap at end of syringe and secure cap by wrapping with Parafilm
  • Leave an airspace in the syringe to accommodate expansion upon freezing
  • Stabilize the plunger by wrapping with Parafilm (no adhesive tape)
    • Do not place pressure on the plunger
  • Place the parafilm secured syringe in a sealable specimen bag
  • Freeze samples for PCR testing within two hours of collection
