METHOD OF PARTIAL LYSIS AND ASSAY

The present disclosure describes a method of treating a sample comprising cells with a process of partial lysing. Cells are exposed to a process such as bead beating that lyses some cells in the mixture. The process generates a resultant sample mixture that is suitable for both cell morphology screening and genetic screening. A first portion of the partially lysed sample can be mounted on a slide and observed for atypical cells and cytologic abnormalities. A second portion of the partially lysed sample can be screened for genetic markers known to correlate with a risk of cervical cancer. Surprisingly the presence of beads in the mixture from the partial lysing process does not interfere with slide processing or cellular analysis. The method is particularly useful for cervical screening, where a combination of cytology and genetic screening present a more complete picture of cervical health. The disclosed method streamlines the diagnostic process for protocols that require both types of assays, without compromising screening accuracy.
