The kit uses an indirect semi-quantitative IgG antibody assay which provides an easy-to-read colour change which clearly distinguishes normal IgG levels (>8mg/ml; colourless), partial FPT (4-8mg/ml; pink) and levels generally considered diagnostic of complete FPT (<4mg/ml; purple).
Vetlabs says the kit has a proven sensitivity and specificity of 97.4% and 93.6% respectively, and responds equally well with anticoagulant whole blood, serum or plasma. And with no additional equipment or refrigerated storage required, it is a true field test.
Mike Fleming, CEO of Vetlab Supplies Ltd said: "It’s not often you get to launch an equine diagnostic that’s genuinely life saving. With Fastest IgG Equine, vets can now give a clear-cut Failure of Passive Transfer (FPT) diagnosis at farms, stables or equestrian centres – and all in just 10 minutes."
According to the company, as many as 1 in 5 new-born foals can suffer some degree of IgG FPT. Foals with no antibody protection, due to complete FTP, have an estimated 75% chance of contracting debilitating or life-threatening infection. Even foals with some protection following partial FPT have only a 50% chance of resisting invaders such as Anaplasma, Giardia and Cryptosporidium.
The new-born foal’s absorption of maternal antibodies is most efficient in the first 6 to 8 hours of life, effectively ceasing after 24 to 36 hours. Veterinary surgeons and managers of equestrian facilities have only this narrow window to recognise FPT and act to save a valuable new-born from life threatening infection.
Mike added: "With Fastest Equine as part of their field kit, equine vets are equipped to diagnose and treat antibody deficient foals with life-saving colostrum, colsotrum formula substitute, or administer oral or intravenous IgG, within that critical first 24 hours."
