National Institute of Health is one of the most prestigious institutions of the country involved in multi disciplinary public health related activities like diagnostic services, research and production of biologicals for the last more than 40 years. The idea of establishing a National Health Center (NHC) was conceived in early 1960's, which started functioning in 1965 at Islamabad, near Rawal Lake, 10 kilometers from zero point. Various independently working organizations like Bureau of Laboratories, Directorate of Nutrition Survey and some other health related research organizations were shifted to NHC. Later on all these independently working departments were integrated and designated as National Health laboratories (NHL - Islamabad).
