IN VITRO ALLERGY TESTING has been available to veterinarians since 1985 with the introduction of the K-9 RAST (Radioallergosorbant Test) program. A number of years later, ELISA (Enzyme Linked Immunosorbant Assays) were made available, essentially similar tests, however using radioisotopes and enzyme color reactions respectively as their means of quantitation.
 

In recent developments, the R & D Department at Spectrum Labs has analyzed each system closely and combined the most reliable aspects of each to bring you the SPOT TEST, the most reliable and advance in-vitro test available.
 

Since its beginnings in 1989, , Spectrum Labs has grown into the premiere allergy diagnostic and treatment center in the world. Veterinarians currently serviced by Spectrum Labs reside in every state of the Union as well as in 18 countries outside the United States..
