Comment = Images of day 5 human embryos for QAP purposes. The images are all animated gif files of multiple embryo images. The primary question used for quality assessments, the QAP question has been modified from 2003 with the introduction of a calculated embryo scrore parameter [ESP]. This allows for the assessment to be based upon the common criteria embryologists used in their daily embryo grading. The sum of each parameter leads to a calculated value that is submitted for assessment and comparison. The multiple images (3-4 animated images) is used to assess comparative judgements for both transfer and for freezing. A text based summary has been included allowing participants to review how others describe and guage embryos. While the replies to all questions can be probed from conformity, the QAP question forms the basis for internal quality control and for external comparison for both each staff member and for the clinic overall. A new question has been added to explore one capacity to identify the inner cell mass.

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.
