Do

  • If excessive mucus is present, this should be gently removed before sampling.
  • Use either the Cervex Brush (broom-like device) on its own or in combination with an endocervical brush.
  • The Cervex Brush should be rotated 5 times in a clockwise direction. The Plastic spatula should be rotated through 360 degrees and the endocervical brush rotated through one quarter to one half turn.
  • Immediately rinse the collected material into the vial.
  • Replace the lid and tighten so that the black torque line on the cap passes the black torque line on the vial to avoid leakage.
  • Keep the unlabelled portion of the sample vial free of labels so that the contents can be seen.
  • If barcoded labels are used these must be applied horizontally around the vial.
  • Samples should be sent to the laboratory without delay.

…an adequate sample from the cervix using a Cervex Brush (broom-like device). Insert the central bristles of the brush into the endocervical canal deep enough to allow the shorter bristles to fully contact the ectocervix. Push gently and rotate the brush in a clockwise direction five times.

Rinse 260Px3 Rinse...

…the Cervex Brush immediately into the PreservCyt Solution vial by pushing it into the bottom of the vial 10 times, forcing the bristles apart. As a final step, swirl the brush vigorously to further release material. Visually inspect the Cervex Brush to ensure that no material remains attached. Discard the brush.
