Subject: The cut-off value will vary between assay set-ups depending on the non-specific background in the specific set-up. pharm. Пожалуйста, помогите перевести второе предложение!!
All samples are screened for antibodies and the cut-off value is set so approximately 5 % false positive samples are selected for confirmation to ensure дetection of low positives. The cut-off value will vary between assay set-ups depending on the non-specific background in the specific set-up. All samples above cut-off in the first screening assay will be subjected to the second step which is a confirmatory assay to find the true positive samples for anti-XX antibodies.
