Improving access to essential tests for infectious diseases.

Abstract Recently, WHO published the first ever Essential Diagnostics List (EDL), which includes 113 tests, including tests for HIV, TB, malaria, hepatitis B and C, human papillomavirus (HPV) and syphilis. The EDL is a welcome first step in ensuring that diagnostics are a key part of all health systems. The impact of the list, however, will depend greatly on how countries adopt and implement the EDL.
