Common Questions About
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.
What is the proper technique for collecting a sample for the ThinPrep Pap Test?
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 water-based lubricant such as Astroglide®. 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.

How long are cells preserved in PreservCyt? In CytoLyt?
Cells are preserved in PreservCyt for 6 weeks at 15-30° C. Cells are preserved in CytoLyt for 8 days at room temperature.
What about sampling during menses?
Menstrual blood can obscure significant findings. Therefore it is preferable to avoid sample collection during menses, and ideal to schedule an exam two weeks after the first day of the last menstrual period (i.e. mid-cycle).1 ACOG and CLSI guidelines state that one should avoid sample collection during menses. According to the CLSI guidelines, a woman should be advised to schedule the examination "two weeks after her last menstrual period and preferably when she is not menstruating."1
