Crias need to consume adequate colostrum from their dams in order to ensure that they are adequately protected from pathogens in their environment. Colostrum contains antibodies and we can measure the adequacy of transfer of these antibodies in crias from 24 hours of age.

It is best to test them between 24 and 48 hours of age but definitely before 7 days of age after which antibody concentrations decline and it is more difficult to interpret the findings. The earlier days are better because the longer you leave it, the cria with Failure of Passive Transfer (FPT) is more likely to get sick and the result is less useful to you in terms of preventing sickness! This is a camelid-specific test and will not measure antibodies acquired from bovine (or any other species’) colostrum.

Frequently Asked Questions

What type of sample is required for IgG Testing?

Please send a serum sample: your vet will need to draw blood and put it in a plain (red-top) tube. Ideally it should be spun and separated (they send the serum sample after the red cells are spun off) before sending but this is not essential as it can be done on receipt of the sample too. Only a small 2ml blood sample is required from your cria.

How long does it take to get results?

Provided that you call ahead to make sure that I am able to receive your sample the following day, after I receive the sample the test takes 40 minutes to run and I am able to report the result. You will receive the result by phone and/or email. We typically call with these results as soon as they are available if the result confirms failure of passive transfer and a plasma transfusion is recommended.

What do I do if the IgG test result is low?

If the IgG test result is low, the cria with Failure of Passive Transfer will need to have an intravenous plasma transfusion. It is also possible that the cria is already getting sick, so more detailed labwork may be required along with appropriate treatment based on lab findings.
