Applications FAQs

1. How long can a GYN specimen collected in PreservCyt be held for ThinPrep Pap Testing?

GYN specimens collected in PreservCyt may be held for up to 6 weeks at temperatures between 15-30° C following collection and prior to processing for the ThinPrep Pap Test.

2. What are some factors that may affect the presentation of a ThinPrep Pap Test slide?

For all pap tests, the use of interfering substances (i.e. lubricants) should be minimized prior to specimen collection. Improper collection techniques, including use of the wrong collection devices, can also adversely affect slide presentation. Please refer to the Customer Training Bulletin on Collection, the Dear Colleague Letter on Lubricants, or the CLSI Document: Papanicolaou Technique; Approved Guideline and ACOG Practice Bulletin, no. 45, August 2003. You will need Adobe® Acrobat® Reader™.

3. Should lubricants be used during pap testing?

Lubricants increase the risk of contaminating or obscuring the cellular sample with both conventional pap smears and all liquid-based methods. The Clinical and Laboratory Standards Institute (CLSI; formerly the NCCLS) recommends that lukewarm water be used to lubricate and warm the speculum. If a lubricant must be used due to patient discomfort or other circumstances, it should be applied sparingly on the outer portion of the speculum with great care to avoid the tip, using a carbomer free lubricant. Please refer to the Customer Training Bulletin on Collection, the Dear Colleague Letter on Lubricants, or the CLSI Document: Papanicolaou Technique; Approved Guideline and ACOG Practice Bulletin, no. 45, August 2003.
