Feds have charged four providers at a San Francisco health care network that sells HIV testing kits to HIV-positive individuals.

The San Francisco AIDS Foundation and two other HIV-care providers are charged with felony counts of illegally selling HIV testing equipment to HIV clients.

The indictment says the four defendants violated federal anti-discrimination laws by not disclosing to clients that they had the HIV testing and did not make sure they were using the test properly.

San Francisco’s HIV-prevention network says the defendants sold their HIV tests for between $100 and $300 each.

In the indictment, prosecutors said the defendants failed to ensure that their HIV-testing kits were tested properly, failed to properly label the products, and failed to report any potential problems.

According to the indictment:One of the defendants was arrested on May 30 and released on $100,000 bail.

He is due back in court July 8.

The other four defendants were arrested May 31 and released $100 of each bail, with the remaining defendants charged with possession of the drugs for sale.
