Please see the attached study, a pilot study in 3 districts/states in India, on availability of essential tests at the level of primary care.
We used the WHO Essential Dx List as the benchmark to conduct this survey.
I hope many such surveys will be done in countries, since the EDL offers countries a benchmark they can use to measure and improve diagnostic services.
