Why should I order Total Immunoglobulins and Wheat Zoomer at the same time?

When ordering Vibrant's Wheat Zoomer, it is helpful to add (for free) Total Immunoglobulins to the order to to investigate a patient's baseline immunoglobulin production and, thus, the accuracy of their antibody response. Please note that Vibrant's Total Immunoglobulins is only offered with serum blood draws. Total Immunoglobulins cannot currently be determined from dried blood spot (DBS) specimen collections.
