Effective immediately, Ploidy FISH for Molar Pregnancy (available as global only) will be performed with the CEN11 probe alone, rather than CEN1 and CEN11 probes, due to a temporary CEN1 probe manufacturing shortage. A review of internal data has determined that the use of the CEN11 probe alone, along with an increase in cutoff values for the abnormalities detected, may allow for an accurate ploidy determination in the majority of cases submitted. Please also be aware that during this time, CPT coding will reflect the original code. Our billing department will be adjusting invoices accordingly.
