Laboratories as the Core for Health Systems Building.

If it is accepted that health care access to diagnosis and treatment is a universal human right, the principal challenge is how to deliver that health care to all people. Health systems that function are the most effective way to deliver such care; these health systems should cover all of the diseases facing a population. The central role of laboratories in making medical decisions is crucial. If organizations engaged in health systems building tackle a disease category, such a cancer, multiple modalities within and outside of the laboratory have to be improved or installed to make an effective system.
