Information on QA Scheme: Halosperm DNA EQA 2024
Comment = An EQA/Competency schemes for the assessment of sperm DNA fragmentation by the Halospem method. This has been expanded to 12 data sets from 2013 with images from several users. Participants are shown 20+ sets of images from one sample and asked to estimate the number Normal and abnormal sperm ( according to the methodology) and calculate a % DFI
Number of enrollments =50 [* This indicates only the number of enrollments. Not all participants will have completed the scheme]
