title: Fallacies in the interpretation of Paul-Bunnel Davidsohn differential test.
abstract: Serological findings in five cases where Paul-Bunnel Davidsohn (PBD) test results were misleading, are presented. Three patients' with Chronic renal disorder and positive PBD test had specific serology results, signifying Cyto Megalo Virus infection. A fourth patient with Hepatitis B Virus infection also had positive PBD test. Forssman type of antibody response was demonstrable in a boy with recent Epstein-Barr virus infection and high Cyto Megalo Virus antibody titres.
