Information
on QA Scheme: Evaluation of Cleavage by time lapse Imagery 2025
Comment = Evaluation of Cleavage by time lapse Imagery. The module uses videos from EmbryoScope as supplied by IVFA. When complete, there will be 12 releases, one per month in 2014. Each will show one video of the complete cleavage stages of a single human embryo. Participants will be as to assess the time to reach critical stages and to grade the final blastocyst.

Title
Blastocyst Score-Ver 1
Comment
This score calculates a blastocyst value from the Gardners Grading Scheme
This
is a calculated Question. It requires a number of other questions
to be completed. The answer to these questions have each been weighted
(see below). The value submitted for each question is then compiled
as detailed below to provide a SCORE usually out of 100. The higher
the score usually indicates a better quality. The score is an arbitary
one and has been generated within QAPonline to allow all the parameters
embodies in the questions to be assess.
