The Treatment Action Campaign (TAC) says it’s ready to litigate against the Gauteng Health Department should it not clear its outstanding debt to suppliers. The TAC adds that the closure of health laboratories in Gauteng and KwaZulu-Natal has severely impacted on people who are HIV-positive and those with TB. Chairperson of the Treatment Action Campaign, Nonkosi Khumalo says the closure of health laboratory services impacts on patients on Anti-retroviral treatment (ARVs) and those who need to be tested for TB. Blood tests are not being done due to the closures. Khumalo says some health care facilities are unable to initiate new patients on ARV treatment because they can’t get their blood tests to laboratories.
