Adaptation of a fluorescent immunoassay for canine haptoglobin

The development and adaptation of a fluorescent immunoassay for determining changes in canine haptoglobin levels is described. Levels of canine haptoglobin determined by the fluorescent immunoassay from a group of healthy dog sera (68.0 mg/dl) compared favorably to the haptoglobin levels determined by a spectrophotometric method (74.5 mg/dl). The fluorescent immunoassay offered several advantages over currently used methods for determining levels of canine haptoglobin in serum.
