A revised binary scoring system generated by the Eeva™ test’s time-lapse microscopy (TLM) software may enhance selection at the cleavage stage

      The Eeva Test’s TLM software automatically generates a binary result (high or low) that prognosticates blastulation rates by day 3 of development. This binary predictive model has previously been studied in patients with normal ovarian responsiveness to assess whether it could aid in selection of euploid blastocysts. Unfortunately, nearly half of the patients studied had all ‘low’ ratings precluding any selection advantage. A revised scoring system was introduced in which embryos previously designated as ‘low’ likelihood of blastulation now may meet requirements to be reclassified as ‘medium’. The goal of the present analysis is to evaluate whether this new scoring system could enhance the utility of the test.
