Most of us agree the liquid based pap test is here to stay.

Four hundred Pap test samples were collected using the Gynemed Trans Os Cervical Sampler.

The patients were selected based on non high-risk criteria. All patients had a WNL Pap result within the last 12-14 months, were not pregnant, and no abnormal clinical findings present at the time of sampling.

The tests were split evenly between conventional and liquid based slide preparations, and screened blindly by
licensed reviewers.

Most of us agree the liquid based pap test is here to stay.

But with all the LBC choices available, the one factor that continues to limit the adequacy and sensitivity of these technologies, is the specimen collection procedure.

Over the last decade, many new devices have been approved by the FDA attempting to improve on this Pap collection procedure. Each of these devices has met with limited success due to the complexity of the steps required.

The Gynemed Trans Os cervical collector extracts optimal diagnostic material and releases virtually all that material into the collection fixative.

Conventional Brush

1. As the conventional cervixbrush is inserted into the cervical os, the bristles collect cellular material from the transmformation and push it up, into the endocervical canal.
2. The Brush is rotated and removed from the cervix.
3. The exposed bristles of the brush push the cellular material up into the endocervical canal, and as the device is removed, much of the material remains behind. This constitutes a “Sampling Error.”
Conventional Brush

1. With the bristles covered, the device is placed into position without displacing the diagnostic material.
2. The cannula is retracted
exposing the bristles in place. The device is rotated 1/2 to 1 full turn and removed from the cervix.
3. The cellular material is extracted as the brush is removed from the cervix.

  • Increased cellular volume collected and transferred
    to the vial.
  • Increased presence of Endocervical/Transformation
    Zone components.
  • Significant increase in abnormal detection rate.
  • Significant decrease in QNS and limited cases.*
