RT Journal Article SR Electronic T1 Satisfactory screening for cystic fibrosis with the BM meconium procedure. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 911 OP 913 DO 10.1136/jcp.34.8.911 VO 34 IS 8 A1 R T Evans A1 A J Little A1 A E Steel A1 J M Littlewood YR 1981 UL http://jcp.bmj.com/content/34/8/911.abstract AB The Boehringer Mannheim test (BM test) for cystic fibrosis has been applied to 15 734 neonates. A positive result occurred in 130, seven of whom were subsequently shown to have the disease. To our knowledge no cases have been missed. Tests have been performed centrally by experienced laboratory staff and the false-positive rate of 0.83% is considered acceptable. It is important to follow up weak as well as strongly positive reactions to the BM test strip.
