Perform a separate analysis for each drug class. 

For specimen 1, use the result from the earliest blood draw.  On the line in the RT column for specimen number 1 (in the SNG column), enter a "1" if the first specimen contains a relevant resistance mutation (see the list on Page 3) and a "0" if the specimen has no relevant mutations. 

For specimen 2, use the result from the second earliest blood draw.  On the line in the RT column for specimen number 2, enter the total number of specimens with a relevant mutation among specimens 1 and 2 -- that is, if neither specimen 1 nor specimen 2 has a relevant mutation, enter "0" on the second line in the RT column; if specimen 1 has a relevant mutation but specimen 2 does not, enter "1" on the second line in the RT column; if specimen 2 has a relevant mutation but specimen 1 does not, enter "1" on the second line in the RT column; if both have relevant mutations, enter a "2" on the second line in the RT column. 

Continue to record information based on the date and time specimens were drawn.  For the third line in the chart, record the number of specimens among the first three specimens that have relevant mutations in the third line in the RT column; for the fourth line, record the number of specimens among the first four specimens, etc.

A classification of HIVDR prevalence can be made when, among the number of specimens  genotyped (see the SNG column), the running total of specimens found with HIVDR (in the RT column on the same horizontal line) is less than the lower limit specified in the LL column to the left of the RT column, or greater than the upper limit specified in the UL column to the right of the RT column.  



When one of these conditions occurs, HIVDR prevalence can be classified either as <5% (if the RT is < than the LL number on the same horizontal line) or >15% (if the RT is > than the UL number).  If neither of these conditions has occurred after the 47th specimen has been genotyped, prevalence is classified as >5% and  < 15%.    Analysis may stop before the 47th specimen is reached if a classification of HIVDR prevalence has been made on the basis of fewer specimens.

Eligibility criteria for HIVDR-TS
HIVDR-TS: WHO eligibility criteria

  • List eligibility criteria used in country each survey from among these:

Eligibility must include: Aged < twenty-five years and no previous pregnancies if female, [and/or laboratory evidence of recent infection (if reliable and valid) or seroconversion]

    • If numbers are sufficient, < 22 years of age

  1. Not eligible to start ART*

  2. No previous positive HIV test*

  3. No known exposure to antiretroviral drugs*

  4. No known AIDS-defining illness*

  5. CD4 count > 500 (where available)*

  6. First risk-defining event within the past 3 years (e.g., drug injection, STI)

  • Use these criteria if they are routinely available at the site
