 The World Health Organization, WHO, recommends point of care, POC, Early Infant Diagnosis, EID, slash viral load, VL, testing for children and pregnant slash breastfeeding women, priority HIV, to increase timely diagnosis. To optimize this diagnostic network, the WHO suggests leveraging existing capacity to integrate these tests into the existing tuberculosis, TB, testing network. By optimizing the diagnostic network, the WHO hopes to decrease the average distance traveled by priority HIV tests and increase the proportion of tests conducted on site. Additionally, the WHO expects to see cost savings due to cost sharing between the two programs. To assess the feasibility of this approach, researchers modeled the impact of integrating EID slash VL testing for children and pregnant slash breastfeeding women, priority HIV, with TB on gene expert in Zambia. Using OptiDX, they established the baseline diagnostic network using inputs for testing demand, October 2019 to September 2020, referrals, testing sites, testing platforms.
