* Proper blood transfusion in time saves millions of lives, but unsafe transfusion practices puts millions of people at risk of blood transfusion transmissible infections. Morbidity and mortality resulting from the transfusion of infected blood have far-reaching consequences, not only for the recipients themselves, but also for their families, their communities and the wider society. In this book, criteria for safe transfusion and transfusion transmitted infections like HIV, Hepatits B, Hepatitis C, Malaria, Syphilis etc. are discussed. Details given in this book are very useful for undergraduate, postgraduate students and faculties of Pathology and other branches of medical science.
