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
