Laboratory capacity to monitor antiretroviral combination therapy

Export Indicator

Percentage of designated laboratories with the capacity to monitor antiretroviral combination therapy according to national and international guidelines To scale up antiretroviral use in resource-constrained settings, WHO categorizes currently available t
What it measures

Laboratory assessment of HIV status and need for treatment is essential to ensure the appropriate and effective use of antiretroviral combination therapy. Monitoring the ability of laboratories to carry out minimal as well as more advanced testing requirements is therefore essential. The purpose of this indicator is therefore to assess the availability of laboratories with the capacity to monitor the people receiving antiretroviral combination therapy according to international guidelines.

Rationale
Numerator

The number of designated laboratories with the capacity to monitor antiretroviral combination therapy according to national and international guidelines Laboratories are classified into three levels as follows: • level 1: they meet the minimum testing requirements for testing categories 1 and 2 (above); • level 2: they meet the minimum testing requirements for testing categories 1, 2 and 3; and • level 3: they meet the minimum requirements for all four testing categories.

Denominator

Total number of designated laboratories

Calculation
Method of measurement

Data will be obtained from a survey of designated laboratories.  Data collection will entail observing the availability of functioning equipment and supplies to run the tests at each level.

Measurement frequency

Every 2-4 years

Strengths and weaknesses

Although this indicator attempts to assess the quality of laboratories by assessing the existence of specific equipment, it does not address human resource needs. Specifically, the presence of a trained laboratory technician available on site to perform the tests required at each level is not currently included.
