    The 591C Densimeter, with the foal IgG calibration, provides a quick and accurate onsite measurement of the foal's immunoglobulin G (IgG) level. This test utilizes a small sample of the foal's blood to determine the concentration of IgG present at the time of the test.

    The 591C Densimeter display shows step-by-step prompts which guide the operator through the IgG test. Automatic temperature stabilization of the test compartment insures maximum accuracy in low temperature environments. The entire IgG test takes approximately 15 minutes and provides an accurate numeric result (mg/dl). There are no color change charts or need to estimate degree of agglutination with this test.

    The Foal IgG Analyzer Kit includes the 591C Densimeter, foal IgG concentration calibration, and all required equipment.

    A Foal IgG Test Supply Kit is required for running the test.  Each kit includes pre-filled measurement and dilution cuvettes, pipette tips, Anti-IgG serum for 10 tests.

    A newborn foal is entirely dependent on maternal antibodies, absorbed following ingestion of colostrum, from its dam in the first few hours of life for immune protection. Failure of the passive transfer of maternal antibodies puts the foal at significant risk of infectious diseases. Monitoring the success of passive transfer by measuring levels of IgG in the blood of neonatal foals is critical if early intervention and treatment is required.

    ARS recommends that this test and treatment of foals with inadequate passive transfer be done under the supervision of their veterinarian.

    An IgG upgrade kit is available to add the IgG capability to a previously purchased 591 Densimeter.

    The 591C Densimeter is a multipurpose instrument capable of quick, accurate estimations of stallion sperm concentration and/or Foal IgG antibody levels. Each Densimeter kit is pre-loaded with the calibration and supplies required for the specified operation. The 591C Densimeter can hold multiple calibrations at a time and additional calibrations may be purchased and loaded via a personal computer. Alternate species calibrations are available for the 591C Densimeter to measure Bull, Boar, Canine, Rooster, and Turkey sperm concentration.
