For the health of the foal, it is very important that sufficient immunoglobulins are absorbed from colostrum in the first hours of life. To determine whether this has happened sufficiently, the amount of IgG in the blood is determined. 
VMRD has developed an IgG test that provides reliable, objective test results. This allows for appropriate therapy to be initiated in time so that the foal receives sufficient antibodies to protect itself from infection. 
The test strips do not need to be refrigerated and can be used with the VMRD reader that is also used for SAA determination.
