The screening RAST: is it a valid concept?
Dr. William King in 1982 advocated the use of a "miniscreen" panel of six antigens to cost-effectively initiate allergy testing. In a study of 100 consecutive patients, we found that a "midiscreen" of nine antigens was more sensitive and efficient and more accurately identified negative responders. However, the miniscreen was also effective if adjusted for regional antigen differences.
