Resignations Follow HIV Test Glitch

The president of a hospital that gave patients hundreds of suspect HIV and hepatitis C tests has resigned, along with two doctors who managed the hospital's laboratory, officials announced. Timothy D. Miller stepped down from the helm of Maryland General Hospital, where more than 400 patients may have received incorrect test results during a 14-month period ending in August. A former hospital lab worker notified city officials last year of problems. Inspectors determined workers manipulated and eliminated machine readings showing that blood tests might be inaccurate and should be discarded. The hospital is trying to find and retest all patients who received the suspect tests.
