What is ImmunIGY Bovine IgG Test?

The ImmunIGY Bovine IgG test is able to rapidly and reliably demonstrate the level of antibodies (IgG) present in calves up to 42 days of age. Using a novel lancet, blood samples can be collected by anyone. The IgG level indicates whether the calf has received sufficient, high quality colostrum in the correct time frame. This is critical as calves which did not receive enough colostrum in the correct time frame, are at higher risk of infectious disease and tend not to perform as well throughout their life. This is known as failure of passive transfer or partial passive transfer.


The ImmunIGY Bovine IgG test can accurately determine a calf’s IgG status in just 10 minutes using a combination of lateral flow technology and a specialised interpretation device. The ImmunIGY Bovine IgG test has been extensively validated to ensure that veterinary surgeons and farmers can rely on the results obtained. This means that there is no longer a compromise between reliability and time or cost to obtain a result.


  • Simple to use on farm & in practice
  • Direct measure of IgG- no need to rely on an estimate from total plasma proteins
  • Fully quantitative, reporting IgG levels in mg/mL
  • Blood sample for running the test acquired via a lancet providing an easy sampling technique
  • Simple to use LFD (lateral flow device) test that delivers a rapid result
  • Validated against laboratory-based methods
  • Requires no special preparation (e.g. centrifugation)
