LA JOLLA, Calif.--(BW HealthWire)--Feb. 22, 2000

La Jolla Diagnostics Inc. (OTCBB:LAJD), announced today the addition of several new products and the acquisition of certain marketing rights.

AllerSpray, developed by La Jolla Diagnostics, is a sub-lingual spray used to obtain relief from symptoms associated with allergies. The original concept behind AllerSpray was developed by Robert Hamburger, MD, a world renowned leader in the field of allergies and now Professor Emeritus at the University of California, San Diego.

"The addition of AllerSpray to our nutraceutical line is important for several reasons." said Stephen Roberts, MD, President. "American healthcare consumers, especially aging baby-boomers, increasingly seek effective, natural alternatives to pharmaceuticals. Dr. Hamburger's association with this product will bring instant credibility among allergists worldwide. Also, our MigraSpray marketing efforts will be greatly enhanced by the availability of a new product for which there is a very broad market. This is the first of several such new products we expect to make available over the next few months." Non-prescription allergy products account for more than $6 billion per year in U.S. sales.

The Company has also obtained certain distribution rights for all of the soy-based meat analog products currently manufactured by Lumen Foods, including the entire line of "Heartline Meatless Meats" and "Stonewall's Jerquee," the best-selling soy snack in the U.S. In addition, Lumen Foods will manufacture a new jerky analog product, "Big Chunk" exclusively for the Company. This product will be fortified with the USRDA of 14 vitamins, and will carry the health claim recently approved by the FDA, "25 grams of soy protein each day significantly reduces the risk of coronary heart disease." Traditional jerky-type snacks are the third best selling snack category in the U.S. and represent an $800 million dollar per year market. Terms of these agreements were not disclosed.

Lumen Foods (www.soybean.com) is recognized as a world leader in the manufacture of innovative, high quality, soy-based meat analogs. Its founder, Greg Caton, has been an active proponent of the ecological and health benefits of soy use for over 10 years, and currently serves on the Company's board of directors.

"We are exceptionally pleased to be associated with Mr. Caton and his company." said Don Brucker, CEO. "His talents in both marketing and new product development are substantial, and are greatly appreciated during this time of rapid change for the Company. That his long-held position on the health benefits of soy has, after 10 years, been affirmed by the FDA simply adds to his already long list of accomplishments."

La Jolla Diagnostics is an emerging company engaged in the development and marketing of health care products, and through its subsidiary DiagnosTech Inc., state-of-the-art rapid diagnostic tests including a unique proprietary test for active tuberculosis.
