Information on QA Scheme: Pronuclear Assessment-2012
Comment = A scheme to QA the assessment status of day 1 human embryos using the modified criteria described by Scott(modified). The Z score used by Scott has been expanded to generate a normally distributed value for QA purposes.
Number of enrollments =181 [* This indicates only the number of enrollments. Not all participants will have completed the scheme]

Title Pronuclear Score-Complex
Comment This score uses Scotts description plus other observations to create a numeric Z score for QA purposes
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.
