We already had stall-side foal IgG tests, so why are veterinarians talking about a new one?

In this video, we break down a recent Equine Veterinary Journal study evaluating a new lateral-flow IgG assay and digital reader for assessing passive transfer in newborn foals. While horse breeders and veterinarians have been using tools like the SNAP Foal IgG Test for years, researchers wanted to determine whether newer technology could provide more objective, repeatable, and potentially more accurate results when making critical treatment decisions.

We'll start by exploring why passive transfer is so important for every newborn foal and how a lack of adequate antibodies can lead to Failure of Passive Transfer (FPT), one of the most significant health risks facing young foals. Then we'll examine how veterinarians have traditionally tested IgG levels, including laboratory methods, refractometers, and the widely used SNAP Foal IgG Test.

From there, we'll look at what makes this new digital IgG testing system different, how the lateral-flow assay and electronic reader work, and what researchers found when they compared the new technology to laboratory reference methods. Finally, we'll discuss the study's limitations, whether this new test is actually better than SNAP, and what these findings could mean for breeders, veterinarians, and foal health in the future.

If you've ever wondered how veterinarians determine whether a foal received enough colostrum, how passive transfer testing works, whether the SNAP Foal IgG Test is still effective, or if newer diagnostic technology is changing equine medicine, this video is for you.
