San Diego County Public Health Services will begin Monday to offer free blood tests to detect the virus believed to be the probable cause of AIDS, acquired immune deficiency syndrome.
The test determines whether a person has been exposed to the HTLV-III virus, not whether a person has AIDS or will acquire it.
Officials caution that the blood test is not 100% accurate.
The blood tests will be conducted at two sites in the San Diego, at the J.B. Askew Building, 1700 Pacific Highway, Monday through Friday, from 8 a.m. to 11:30 a.m. and 1 p.m. to 4 p.m., and at the East San Diego Health Center, 5202 University Ave., on Mondays from 5:30 p.m. to 8:30 p.m.
In Chula Vista, the blood test will be given at South Bay Health Center, 263 Fig Ave., on Tuesdays from 5:30 p.m. to 8:30 p.m.
