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.
The 591B Densimeter, when
loaded 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
591B 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 591B Densimeter, foal IgG concentration calibration, and all equipment and supplies needed for the first 20 tests. Each kit includes pre-filled measurement and dilution cuvettes which minimize onsite setup time and
help insure accurate results. Additional Foal IgG Test Supply Kits are sold with all supplies needed for ten (10) tests.
ARS
recommends that this test and treatment of foals with inadequate passive transfer be done under the direction of their veterinarian. An IgG upgrade kit is available to add the IgG capability to the 591B Sperm Counter.
