Newer diagnostics produce results data in digital format (also known as electronic data). Unlike written data on paper, electronic data can be rapidly and accurately sent and analysed using a diagnostics connectivity solution. These solutions give TB programmes the ability to remotely monitor network performance for quality assurance purposes, transmit test results automatically to clinicians, laboratory information management systems or electronic registers, and manage inventory at sites in real-time, along with other advantages. This guide provides an overview of diagnostics connectivity solutions, and what is required to establish one and use it effectively.
