Abbott, Direct Relief International and the Abbott Fund have announced that they have now handed out over 20 million rapid HIV tests.
The major milestone has been reached through work over the last decade, which has seen the kits being given free of charge to counselling programmes in 43 developing countries around the world.
So far, more than 150 partner organisations have joined forces, with over 8,000 health facilities benefitting.
As a result of this work, at least 150,000 new cases of HIV have been averted in infants.
Katherine Pickus, divisional vice president of global citizenship and policy for Abbott and the vice president of the Abbott Fund, said: "Helping pregnant mothers to know their HIV status is a critical step in advancing access to treatment and preventing the transmission of HIV to children."
She added that people who are poor or living in rural areas should have equal access to the benefits of HIV prevention and treatment as those who have money or are based in urban areas.
