16.6.3 The HIV Rapid Test algorithm
An algorithm is a set of guidelines that enables you to follow the steps in a prescribed course of action, with pathways at each step depending on the results. Figure 16.2 shows you the algorithm approved for HIV Rapid Testing in Ethiopia.
As you can see from Figure 16.2, if the first test is positive, in order to be certain whether the client really is HIV infected, there is the need to conduct a second test to confirm the result of the first test.
What does the algorithm in Figure 16.2 say should happen if the second test is negative (it contradicts the result of the first test)?
The algorithm requires a third test to be conducted as a ‘tie-breaker’ — the third test will either confirm the positive result obtained by the first test, or it will confirm the negative result obtained by the second test.
Following the steps in the algorithm ensures that a positive test result has been clearly confirmed by two different tests before the result is given to the client.
