Hepatitis viruses clinical and laboratory diagnosis overview with simple approach for undergraduate and early post graduate in biomedical science field. It discusses viruses, genotypes, simple laboratory techniques for detection, molecular techniques. Complete discussion of viruses hepatitis A, B, C, D and E was carried out in the text.
