(PMTCT_EID) Percentage of infants born to HIV-positive women who received a first virologic HIV test (sample collected) by 12 months of age
This percentage is a proxy measure, relying on PMTCT_STAT_POS + HTS_TST_POS (Post ANC1: Pregnancy/L&D/BF) as a proxy denominator for total number of HEI. Reviewing infants with a first virologic test (N) against this proxy denominator should be done with caution; see assumptions and limitations in the data quality section below.
Number of infants who had a first virologic HIV test (sample collected) by 12 months of age during the reporting period
PMTCT_STAT_POS + HTS_TST_POS from the Post ANC1: Pregnancy/L&D/BF modality. (see PMTCT_STAT & HTS_TST reference sheets)
This indicator measures the extent to which HIV-exposed infants receive a first virologic HIV test to determine their HIV status by 12 months of age. The indicator is disaggregated by the age of the infant at the time of sample collection, specifically between birth and 2 months and between 2 and 12 months of age.
Only samples collected for the first virologic test for each HIV-exposed infant should be counted in this indicator, including dried blood spots (DBS) and samples collected for POC testing (e.g., Alere, Xpert). Even though there is ongoing exposure of infants to HIV (through breastfeeding), this indicator only measures access to a first test, and not access to all the recommended HIV tests throughout breastfeeding. HIV status of infants at the end of the breastfeeding period and the outcomes of the PMTCT program are measured in PMTCT_FO.
How to review for data quality:
Infant testing coverage (PMTCT_EID / PMTCT_STAT_POS + HTS_TST_POS from the Post ANC1: Pregnancy/L&D/BF modality) is a proxy calculation, relying on PMTCT_STAT_POS + HTS_TST_POS from the Post ANC1: Pregnancy/L&D/BF modality as a proxy denominator for the total number of HIV exposed infants (HEI). Reviewing infants with a first virologic test (N) against these denominator results) should be done carefully—see assumptions and limitations below. Review of outlier percentages for testing coverage by age band is recommended (e.g., review high and low outliers for 0-≤2-month testing coverage disaggregate).
Assumption: the total number of HIV positive pregnant and breastfeeding women, and therefore HEI, does not significantly vary quarter by quarter. We would not expect all the women reported under PMTCT_STAT_POS to have given birth to the infants reported under PMTCT_EID. However, despite that time period mismatch, the assumption is that the total number of HIV positive women (estimated HEI) does not vary significantly quarter by quarter, so it is reasonable to compare infants tested to the STAT_POS & HTS_TST_POS PostANC1: Pregnancy/L&D/BF denominator from the same reporting time period.
See the PMTCT_HEI_POS indicator reference sheet for a description of considerations and limitations in calculating proxy positivity for HEI (PMTCT_HEI_POS / PMTCT_EID).

Disaggregate descriptions & definitions:
Infant Test by Age at Sample Collection: For the numerator to be calculated, implementing partners are required to report:
The numerator is a measure of sample collection for virologic testing. Throughout the reference guide the term “received a first virologic test” specifically means “had a first sample collected for virologic testing.” Age refers to age at specimen collection
Calculated indicator, sum of: PMTCT_STAT POS: 1) Newly Tested Positive, 2) Known Positive at entry (see PMTCT_STAT reference sheet for more details) and HTS_TST_POS: Post ANC1: Pregnancy/L&D/BF modality (see HTS_TST reference sheet for more details)
Indicator changes (MER 2.0 v2.2 to v2.3):
Denominator is updated to include women identified as positive after ANC1, including later in pregnancy, at L&D, and throughout the breastfeeding period. These women are reported under the newly added HTS modality: Post ANC1: Pregnancy/L&D/BF.
PEPFAR Support definition:
Standard definition of DSD and TA-SDI used.
Provision of key staff or commodities for PMTCT includes: commodities such as test kits, ARVs including infant prophylaxis, lab commodities, or funding for salaries of health care workers.
Ongoing support for PMTCT service delivery improvement includes: training of PMTCT service providers, clinical mentoring and supportive supervision of PTMCT service sites, infrastructure/renovation of facilities, support for PMTCT service data collection, reporting, data quality, QI/QA of PMTCT services support, ARV consumption forecasting and supply management, support of lab clinical monitoring of patients, supporting patient follow-up/retention, support of mother mentoring programs.
Guiding narrative questions:
1. Provide context for low EID testing coverage by geographic area or partner/implementing mechanism, including any planned activities/remedial actions. For example, PMTCT_EID is lower than previous quarters due to a stock out of DBS reagent.
