Information on Calculated Questions.
Detailed Information on Question: What is the embryo score for this blastocyst
Status This is the KEY QAP Question for the Scheme    
Type Calculation Outcome

1 The calculated score for this embryo is

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.
