Comparison of the effectiveness of two liquid-based Papanicolaou systems in the handling of adverse limiting factors, such as excessive blood

Abstract

The cell enrichment process of the SurePath system capably handled significantly greater amounts of potentially obscuring blood than the membrane filtration method of the ThinPrep system, which was compromised by as little as <or= 1 drop of packed erythrocytes (1 drop = 65 microL).
