Information
on QA Scheme: Pronuclear Assessment-2018
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 =66 [* This indicates only

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.
