Dengue NS1 Antigen IgG Test

Our bodies have antigens that are created by the immune system that help the body in fighting antigens such as viruses and bacteria. The immunoglobulin test is used to measure the number of antigens in the blood. The IgG or Immunoglobulin G is used to measure the antigens in the body that protect against bacterial and viral infections. The IgG test helps the doctors to find out more about the immune system of the body and point out the problem areas. Our body remembers an antigen if it has entered the body once, then it mirrors the process that was taken to fight against it if it re-enters the body; this means that our body remains better prepared for the attack. The immunoglobulin test also helps the doctor in identifying immunodeficiencies that a person is either born with or acquires during the course of time. It also helps in testing if you are affected by Dengue.

If there are any special preparations required for the test, your doctor will let you know about them. You only 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, make sure to wear short-sleeved T-shirt or Shirt to make it convenient. You can also wear sleeved shirts that roll up easily.

The test results are usually available in a few days’ time. The normal range of IgG is 620 to 1400 mg/dl. If the result is positive in the initial blood sample, it may mean that you became affected by Dengue in the recent weeks. If your result is negative, it means that you are not affected by Dengue.

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.
