Priority components include near-POC viral load and EID (to compress time-to-result and enable same-day or next-visit decisions), CD4-based triage for advanced HIV disease alongside cryptococcal antigen (CrAg) lateral-flow testing and urine LAM for TB in eligible patients, and HIV self-testing with assisted linkage for populations that under-utilize facility testing (particularly men in rural areas). This evidence concerns the gene CD4 and tuberculosis.
