Point of care testing for antiretroviral therapy-related lactic acidosis in resource-poor settings.

Lactic acidosis is a rare but potentially life-threatening complication of antiretroviral therapy (ART) and is commonly considered in the differential diagnosis of patients on ART. In the developing world, definitive diagnosis by laboratory measurement of lactate may be impossible. Point-of-care devices are available that provide simple, accurate measurements of lactic acid levels at relatively low cost. Their use in an HIV treatment programme in rural Haiti has greatly assisted clinical decision-making in patients with symptoms suggestive of lactic acidosis.
