The Pasteur Institute of India, Coonoor carries out the estimation of rabies serum neutralizing antibody content by a method called Rapid Fluorescent Focus Inhibition Test (RFFIT) for rabies vaccine immunized human and other pet animals in order to confirm the production of rabies neutralizing antibodies in the immunized individuals and other pet animals.
By performing this test, we can confirm the immunized person or other pet animals whether they have got minimum protective level of rabies antibodies to protect them against rabies infection and also preventing rabies transmission.
This test is useful to find out the level of rabies neutralizing antibody present in the immunized person, laboratory workers and professionals (doctors), all pet animals and in the manufacturers of equine or human rabies immunoglobulin production units and vaccine manufacturers to perform their field efficacy studies.
Collect the blood sample and separate the serum aseptically as detaild below (I) and transfer the serum sample into a sterile screw capped vial, tightly close the vial put it in a polythene bag. Send it in a thermocol box containing ice coolant.
(I) Separation of Serum
(1) Collect blood in a Sterile 2 ml or 5 ml syringe / Vacutainer (without containing anticoagulants / Seperating Gels /Clot activators).
(2) Transfer the blood in a sterile glass / polypropylene tube (without containing anticoagulants/ Separating Gels/ Clot activators).
(3) Keep it at room temperature for 30 to 60 minutes for clotting or allow until to clot.
(4) Then centifuge the tube for 5 to 10 minutes at about 2500 Revolution per minute (RPM).
(5) After Centrifugation, transfer the light yellow coloured, clear supernatant alone in a sterile Nunc vial /tube. Minimium 0.5 ml of serum sample required for the test.
(6) Close the container properly and label it.

Collect your dog/cat’s blood sample and separate the serum aseptically as detailed below (II) and transfer the serum sample into a sterile screw capped vial, tightly close the vial put it in a polythene bag. Send it in a thermocol box containing ice coolant. With the help of veterinary doctor give the following details of your dog/cat:
Send the sera samples in sterile vials tightly closed and sealed with a cello tape. We need to have about 5 ml. of serum per sample. If the sample is hyper immune equine origin or intermediate bulk sample, please inform the expected neutralizing titre value in order to choose the dilution of serum in the test to be included. The samples should be sent in a thermocol box containing ice coolant.Results:
The results will be sent to the given address within 15-20 days, after the receipt of the sample, by Speed Post. On request, the scanned copies will be sent by email in advance.Testing Charges:
The cost of testing charge is Rs.3000/- (Rupees three thousand only) per sample. The payment may be made in the form of Demand Draft drawn in favour of “The Director, Pasteur Institute of India” payable at ‘Coonoor’.
