Utilization of Chromogenic In Situ Hybridization to Assess Ploidy in the Diagnosis of Hydatidiform Mole.

Objectives: Ploidy assessment is often required for the diagnosis of partial molar pregnancy. While fluorescence in situ hybridization has been shown to be effective, it is not available in many laboratories. We validated chromogenic in situ hybridization (CISH) for this purpose.
