BUSINESS MEMOS: AIDS VIRUS TEST KIT

A second test for the AIDS virus that Americans can take at home went on sale nationwide last week.

Home Access Health Corp. of Hoffman Estates, Ill., began taking orders via a toll-free telephone number for its Home Access Express test kits Wednesday, two days after approval by the Food and Drug Administration.

The kits let people take a blood sample at home, mail it to a laboratory and, three business days later, learn by telephone if they have the HIV virus that causes AIDS.
