This is a practical guide to the investigations available for all paediatric disorders, with an emphasis on the routine tests that can be carried out based on the presenting symptoms. Organised by major body systems, the book provides answers to all the questions that arise when investigating a child, such as: 'How selective can I be with the application of tests?'; 'How do I do the test?'; and, 'What do the results mean?'. By providing practical and concise information, The Handbook of Paediatric Investigations will be an invaluable resource for all those involved in the decisions on the care of children.
