We offer a wide range of immunologic tests. These include the following:

  • Tests for evaluation of hyperproteinemias and immune deficiencies: This includes serum, body fluid and urine electrophoresis and individual quantification of immunoglobulins.
  • Tests for immune-mediated disease: This includes antinuclear antibodies (ANA) testing, rheumatoid factor (RF) testing, Coombs testing and crossmatch (for transfusion and diagnostic purposes, i.e. mare-foal or mare-stallion incompatibility).

For most of our immunologic tests, serum is the required specimen. This does not include Coombs testing and crossmatches, where EDTA blood is also required.
