The purpose of this document is to describe the approach that will be used to enable the exchange of information related to laboratory results between the DISA Laboratory Information System and Mozambique’s Electronic Patient Tracking System (EPTS) that is based on OpenMRS. The first phase of implementation will focus on the exchange of viral load (VL) results; however, the approach will eventually include other laboratory results, including early infant diagnosis of HIV (EID) and CD4.
