When obtaining cervical samples, whether the samples are taken from the transformation zone and whether abnormal cells are missing must be considered. Statistical analysis The results are expressed in percentages and frequencies for all parameters.
Koss [ 19 ] answers this question by referring to some very early papers, including Sedlis et al. Cervical mucus, liquid-based cytology, sampling studies, cervical cytology. Accordingly, the authors concluded that the cervix should be wiped at the discretion of the clinician.

Moreover, a higher rate of inflammatory bu was found to be present in the CS compared to the SS, whereas more epithelial cells with clear nuclear details were present in the SS compared with the CS Figure 2likely owing to the fact that these are living cells that are attached to the cervical surface, and if these are actively removed, their cytological characteristics will be more well-preserved at the time of fixation Figure 3.
An example of the amout of mucus retired. The SS was obtained from the transformation zone using a cervical cytobrush or broom depending of the nature of the TZ.

The cervix in most women is coated with mucus or secretions of varying appearances, ranging from very scant to abundant.
Open in a separate window. Dysplastic cells of the same patient, in A from the Cs, with more inflammatory cells, and the nucleus of the atypical cells are note clearly seen. Am J Obstet Gynecol. CS is the result of exfoliated cells from the cervix and vaginal wall, novaak contains inflammatory cells and bacteria in addition to the mucus secreted from the endocervical glands, which are normally found in the cervical orifice.
Support Center Support Center. A biopsy was performed in cases, in xe acetowhite imaging was seen; of these, 24 cases had a previous positive biopsy. The sensitivities for CS and SS were All biopsy samples were stained with hematoxylin and eosin as per standard protocol and analyzed by immunohistochemical staining for cyclin-dependent kinase inhibitor 2A p16 clone J6; Cell Marke, CA, USAusing the CIN classification [ 16 ].
In cases of atrophy or if the SQCJ was not visible in endocervical canal gineecologia a very small orifice, two devices were used: Solomon D, Nayar R. This case was diagnosed as vaginal condyloma, and the biopsy showed characteristic papillary and koilocytic changes.
