In this post we are going to list some basic safety precautions against infections in the laboratory. All specimen arriving in the laboratory should be regarded as being potentially pathogenic. It is very wrong notion to think that only specimen meant for bacteriological investigations are infectious. A specimen of cerebrospinal fluid send for glucose estimation […]
