Use of the Cytobrush for concurrent endocervical cytology and chlamydia sampling.

In 899 women attending a genitourinary medicine clinic Chlamydia trachomatis was tested for using both a Cytobrush and a conventional swab. In 425 cases, the Cytobrush was used for concurrent cytology and chlamydia sampling. Both methods were equally effective in the detection of chlamydia, and, in addition, the Cytobrush gave a higher yield of inclusion bodies per sample. The use of the same instrument for both cytology and chlamydia screening may represent a saving in time and money.
