HIV Early Infant Diagnosis

HIV Early Infant Diagnosis (EID), also known as DPI (Diagnóstico Precoce Infantil), uses PCR-based testing to detect HIV infection in infants born to HIV-positive mothers. Early diagnosis is critical for timely initiation of antiretroviral therapy (ART), significantly improving survival outcomes for HIV-exposed infants.

The OpenLDR Analytics API provides 35 EID endpoints organized across three categories, covering the full spectrum of EID program monitoring — from national dashboard indicators to facility-level sample tracking and laboratory equipment analytics.

Overview

The EID module supports both conventional (centralized PCR) and point-of-care (POC) testing platforms. All endpoints accept a lab_type parameter to filter by testing methodology:

Conventional: Samples processed in centralized reference laboratories using high-throughput PCR platforms (CAPCTM, ALINITY, M2000, C6800, PANTHER)
Point-of-care (POC): Rapid testing at the health facility level using devices like mPIMA
All: Combined results from both testing platforms (default)

Key analytics provided include:

Positivity rates: HIV-positive and negative result tracking
Turnaround time (TAT): Six-segment hub-chain measurement from specimen collection through result validation
Equipment utilization: Sample distribution across 7 equipment types
Sample routing: Geographic flow of samples between health facilities and testing laboratories
Age group analysis: Infant age stratification (0-2, 2-9, 9-18, 18+ months)
