Biomerica Inc

Biomerica Inc. said its Allergy Immuno Technologies Inc. unit has been issued a patent for a new method of treating allergies. In a press release, the company said the latest patent covers an invention under which an allergen--the material to which a patient is allergic--is combined with something called a biological response modifier. The patent covers a class of such modifiers. Biomerica said it plans to enter a "collaborative arrangement" with a drug company to use the invention.

Biomerica Inc., a maker of home medical testing products, said Tuesday that two of its products are being distributed nationally by McKesson Drug Corp. to about 1,400 pharmacies. The Newport Beach company said its EZ Detect Stool Blood Test and EZ Detect Urine Blood Test, both of which provide warning signs of cancer and other diseases, are being offered to pharmacies through McKesson's network of 40 distribution centers.
