RT Journal Article SR Electronic T1 DIAGNOSTIC DIFFICULTIES IN MILD HAEMOPHILIA AND CHRISTMAS DISEASE JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 475 OP 477 DO 10.1136/jcp.13.6.475 VO 13 IS 6 A1 Fessey, Barbara M. A1 Meynell, M. J. A1 Cooke, W. T. YR 1960 UL http://jcp.bmj.com/content/13/6/475.abstract AB Two cases of haemorrhagic diathesis are described, where the laboratory diagnosis was confused owing to previous blood transfusions. Without the help of investigating the relatives, the nephew of Case 1, the haemophiliac, and the uncle of Case 2, with Christmas disease, there would have been considerable delay in reaching the diagnosis and so instituting the correct treatment.
