Scientists unveil new HIV blood screening system

Researchers in Germany have developed a new assay system, or detection method, for determining how well viral inhibitors work in HIV-positive blood.

The system, called EASY-HIT, uses cell cultures to test inhibitors. The cells, which have been genetically modified, are infected with HIV under laboratory conditions. The presence of HIV replication is indicated by a protein that causes the cell to fluoresce a red color.

With the addition of HIV inhibitors, the observed rate of infection in the cell culture changes accordingly.

The fluorescent protein allows researchers to determine how well inhibitors work in preventing the spread of HIV through the bloodstream.

Its creators believe that the system may contribute to more effective retroviral inhibitors.

Currently, HIV has no cure. Those concerned that they have contracted the disease may consider investing in online testing services for sexually transmitted diseases.

More than 18,000 Americans die of AIDS every year, according to the latest data from the Centers for Disease Control and Prevention.
