Foal IgG Test


Ten to twelve hours after birth, a neonatal exam is performed and a blood sample is drawn from the foal. The sample is used for the IgG test which calculates the passive transfer level of maternal antibodies passed from your mare to her foal. Low levels may lead to infection, disease, and increased death rates.



IgG Level Interpretation
< 200 mg/dl Complete failure of passive transfer
< 400 mg/dl Failure of passive transfer
400-800 mg/dl Partial failure of passive transfer
> 800 mg/dl Adequate passive transfer of colostral antibodies
