We evaluated the effect of storage at 2 to 8°C on the stability of human genomic and human papillomavirus (HPV) DNA stored in BD SurePath and Hologic PreservCyt liquid-based cytology media. DNA retained the ability to be extracted and PCR amplified for more than 2.5 years in both medium types. Prior inability to detect DNA in archived specimens may have been due to failure of the extraction met...

OBJECTIVE Liquid-based cytology (LBC) for cervical screening is becoming increasingly used. Together with SurePath LBC, various collecting devices can be utilized, among which the Cervex-Brush is the most widely used. The new Rovers Cervex-Brush Combi combines the advantages of the Cervex-Brush with the EndoCervex-Brush increasing sampling of the endocervical canal. The objective of this study ...

OBJECTIVE Conventional smear (CS) using fine-needle aspiration cytology (FNAC) has been established as the test of choice for diagnosing thyroid lesions, despite low sample adequacy and inter-individual variations. Although a liquid-based preparation (LBP) technique has been recently applied to overcome these limitations, its clinical utility and its accuracy over CS are controversial. This stu...

The SurePath liquid-based Pap test (LPT) is successfully and widely used to assess sputum cytology. This study aimed to compare the cytological findings and diagnostic sensitivity of LPT with those of the conventional Pap smear (CPS) method for diagnosing lung cancer. Bronchial brushing specimens from 204 patients diagnosed with lung cancer were studied. LPT slides showed decreased areas of cel...
