Further information

The Fassisi Bovine lgG is a reliable method to check the success of a passive transfer of bovine lgGs from mother to calf.

The test distinguishes between the following concentrations, which provide information on the success of the transfer:

  • the lgG concentration in the sample is > 10 mg/ml; the lgG concentration is high, a successful transfer can be assumed
  • the lgG concentration in the sample is 5-10 mg/ml; the lgG concentration is moderate (PFPT=partial failure of passive transfer), it can be assumed that the transfer of passive immunity has partially failed
  • the lgG concentration in the sample is < 5 mg/ml; the lgG concentration is too low (FPT = failure of passive transfer), there is poor or inadequate transfer of passive immunity


This means that the bovine lgG concentration can be determined directly on site and, if necessary, immediate measures can be taken to provide the animal with sufficient immunological protection and protect it from possible infections.

* The test can be performed with whole blood as well as serum/plasma/whole blood supernatant. When using the test, it is recommended to use serum/plasma/whole blood supernatant in order to achieve the highest possible sensitivity/specificity. Note on test interpretation: The stronger the T-line, the lower the IgG concentration in the sample.
