Early viral load testing (at 6 months)

Export Indicator

Number and percentage of people living with HIV on ART who had viral load monitoring at 6 months after initiation of ART
What it measures

This indicator measures progress towards promoting early adherence and VLS on ART.

  • WHO currently recommends VL testing for all people living with HIV at 6 months after ART initiation to assess VLS and, in the event of non-suppression, to identify persons in need of intensive adherence counselling and follow-up.
  • This indicator is central to understanding early non-adherence risk and to enable critical interventions to improve adherence and VL suppression and reduce the risk of HIV drug resistance.
  • This indicator is closely related to VL monitoring.

Method of measurement

For the numerator and denominator. Programme records (for example, ART register, cohort reporting forms, patient records, laboratory information systems)

The time window for early VL monitoring can include a margin of +/- 1 month, that is, a routine VL test can take place anytime from 5-7 months after initiation of ART.

  • Gender (male, female, transgender)
  • Age (0-4, 5-9, 10-14, 15-19, 20-24, 25-49, 50+)
