This text is aimed at MRCP candidates, medical students and teachers of medicine. It should enable readers to assess their ability to identify and interpret laboratory data, a skill which is specifically tested in the MRCP Part 2 examination. The questions presented cover a variety of clinical conditions in the format of ten practice papers which can be used for revision. Both authors have many years experience of Membership teaching and all MRCP Part 2 candidates should find this book useful. The book contains ten Data Interpretation Papers covering the broad range of topics as present in the current MRCP examination, plus correct answers and expert teaching notes for each question. A listing of differential diagnoses provides a useful aid to recognizing specific data patterns and there is a table of normal ranges. Questions include ECGs, echocardiograms, lung function tests, cardiac catheter data, audiograms, genetic diagrams, osmotic fragility curves, biochemical and haematological data and more.
