Leptospira Antibody IgG Test

The Leptospira Antibody test is conducted to measure the level of Leptospira Antibody – IgG in the blood. The test is also performed to confirm Leptospirosis. It is also used during and after the treatment.

You do not need to prepare specifically for the test. You have to make sure that you have gathered all the information from your doctor and are well aware of the process and the medications. Apart from this, your doctor would also like to know the medicines or supplements you take as certain medications can affect the test.

After analysing your blood sample, the results come out. IgG is detected in cases where there is some remote infection present. If your test result is positive, it hints towards a recent case of infection.

The procedure is done using the ELISA or Enzyme immunoassay method. For the test, your doctor or lab technician will place a plastic band on your upper arm; this is done to fill up the vein with blood and swell up. Then, he or she will clean the area with an antiseptic and put a needle. He will then draw a blood and keep it in a vial or tube. The plastic band and needle are removed and a bandage is applied to the area to stop the bleeding. The whole process usually takes a few minutes. The collected blood is then sent to the lab for analysis where it is added to a known antigen and mixed with an enzyme.
