Abstract
The occurrence of cervical cancer is often linked to a previous infection with a human papillomavirus (HPV). In order to detect HPV infections in cervical smears, a broad range of tests can be used. This study compares the two hybridisation-based DNA-microarray systems “HPV 3.5 LCD-Array” (Chipron GmbH) and “PapilloCheck®” (Greiner Bio-One GmbH), based on their ability to detect and differentiate HPV infections in 42 different cervical smears. PapilloCheck® can detect and individually identify 24 HPV types, whereas the 3.5 LCD-Array can differentiate among 32 HPV genotypes. However, both systems include all 13 high-risk (HR)-classified types. With Chipron having already stopped the production of the 3.5 LCD-Array test, quite a few laboratories are confronted with the need to establish a new HPV testing method. The two methods were found to have a high agreement regarding the clinical significance of the detected HR HPV types. Discrepant cases were additionally validated with the help of a third test (VisionArray® HPV, ZytoVision GmbH). The results of the VisionArray® test corresponded rather well with the results of the 3.5 LCD-Array.
