Immunodiffusion Test

Maryland rates for HCPCS 86329

A laboratory method in which a sample and a matching reagent spread toward each other through a soft gel and form a visible line where they meet, showing that a specific antibody or protein is present. It is reported for substances that do not have a standard named test of their own. It gives a present-or-absent style answer rather than a precise measured amount.
