Laboratory investigations are an important aspect of diagnostic work-up in clinical practice. Many diseases with identical clinical presentation can only be differentiated by suitable investigations undertaken at the appropriate time and if doctor knows about their fallacy, specificity and reliability he has to interpret them in the light of the total clinical picture. When pushed in a blind corner these tests only direct the doctor in which direction to proceed.
This compact and concise volume deals with all common laboratory investigations like urine, blood, semen and X-rays which are ordered in day-to-day practice. In this edition normal values have been incorporated and the chapters on blood and radiological diagnosis have been expanded.
More sophisticated and cumbersome investigations have been deliberately omitted to keep the book handy and for easy assimilation by the students and practitioners.

7Preface to the First Edition
Success of the treatment depends upon the correct diagnosis of the diseases. To reach this goal the clinician has to go through the different procedures which include proper history and detailed clinical examination. In addition many patients require common investigations while few require special ones.
The facilities for special investigations are available only at limited centres whereas common investigations which fulfil the needs of the majority of the patients can be carried out at averagely equipped hospital. Interpretation of common investigations play a key role in reaching the final diagnosis on which depends proper treatment and relief to the patient.
In this book an effort has been made to fulfil this aim. It consists of examination of urine, blood, stool, CSF, semen and vomitus, etc. It also includes ECG, X-ray and other common investigations.
We hope the book will be useful to the students of medicine and the practitioners alike.
