SNAP® Foal IgG Test

Test and treat foals in a single visit


SNAP® Foal IgG test gives fast, accurate results in just minutes—enabling you to detect low levels of IgG and begin life-saving treatment immediately.

Quick and Accurate Detection of Neonate IgG Levels is Critical.

  • Low levels of IgG can lead to bacterial infections, arthritis, pneumonia and enteritis.
  • Up to 25% of foals may have low levels of IgG.1
  • Foals have only 24 hours after birth to absorb immunoglobulins from the colostrum.
  • Delayed test results necessitate costly intravenous delivery of immunoglobulins.
  • If left untreated, defenseless foals may die.
