WHO Antenatal Care (ANC) Indicator 12
Percentage of pregnant women counselled and tested for HIV

Numerator: Number of pregnant women attending ANC who received counselling and testing for HIV during pregnancy  
Numerator Computation: COUNT of all women who received provider-initiated counselling and testing (PICT) 
Denominator: Total number of antenatal clients with a first contact 
Denominator Computation: COUNT of all women whose records were closed (ANC close form) in the last reporting period due to any of the reasons below:
*live birth
*stillbirth
*miscarriage
*abortion
*woman died
*lost to follow-up
*moved away

Disaggregation:
Age (10-14, 15-19, 20+)
Education Level (none, don't know, primary, secondary, higher)
