What is Immunoglobulin?
Immunoglobulin is the protein produced by plasma cells and leukocytes. Immunoglobulin functions as an antibody. It plays a significant role in the body’s immune system by attaching themselves with foreign substances like harmful bacteria and other microbes and destroying them. Immunoglobulins either reside on the periphery of the cell or it can even more freely in the blood. When circulating in the blood, immunoglobulins are termed as antibodies.
What is Immunoglobulin A?
Immunoglobulin A consists of 10%-15% of the total antibodies. It is found mostly in the mucosal area in the gut, saliva, tears, breast milk, respiratory tract and the urogenital tract. It prevents the invasion of pathogens in the body. There are two isotypes of immunoglobulin A:
– IgA1: predominantly found in the serum.
– IgA2: mainly found in secretions.
What is Immunoglobulin A Test?
Immunoglobulin A Test is used to measure and monitor the amount of immunoglobulin A antibodies in the blood. This test is also used for diagnosing autoimmune disorders and cancers. Immunoglobulin A Test is not too specific and hence it cannot determine the exact reasons for the IgA antibody fluctuations in the blood. The Immunoglobulin A Test just assess the content of IgA antibodies in the blood.

– Immune System

What is the procedure of the Immunoglobulin A Test?
The Immunoglobulin a test is carried out using a blood sample which is collected by the process of venipuncture. The procedure is as follows:
– A tourniquet is wrapped around the upper arm to make the veins more prominent.
– A syringe or needle is used to draw blood by puncturing the vein.
– The blood is drawn into the tube of the syringe. The tourniquet is unwrapped.
– An antiseptic is applied to the spot of venipuncture to avoid any infection. The spot of injection of the syringe is dabbed by a cotton swab or a bandage is put to stop any further bleeding.
– The blood sample is then sent to the laboratory for the Immunoglobulin A Test test.
What is the procedure of the CSF(Cerebrospinal Fluid) test for Immunoglobulin A Test?
The procedure of collection of Cerebrospinal Fluid includes:
You will have to lie down on your side with the knees pulled closer to your chest and the chin bent downwards. The CSF can also be collected while you are sitting bent forward.
The practitioner then applies a numbing cream or inject a numbing medicine(anaesthesia) in the lower back of the spinal cord. Once the area on your back is completely numb, a needle or a syringe is injected in between two vertebrae of the spinal cord.
The CSF is collected inside the tube of the syringe. It can take about five minutes. You need to stay still as the cerebrospinal fluid is being withdrawn. As the CSF is collected, the area of the puncture is cleaned and bandaged.
You might be asked to lie down on your back for an hour or two after the CSF(Cerebrospinal Fluid) sample collection. This will help you avoid getting any headache afterwards.

There are no risks related to this test. The procedure of blood collection(venipuncture) might have some risks associated with it:
– Some people feel light-headed and dizzy after the blood is drawn.
– It might cause Hematoma (blood accumulating under the skin causing a lump or bruise).
– There might be pain associated with too many punctures for finding a vein.
What are the risks of Immunoglobulin A CSF(Cerebrospinal Fluid) Test?
– Discomfort or pain during the procedure.
– Bleeding into the spinal cord, particularly in people having a low platelet count (thrombocytopenia).
– Headache as a result of CSF leakage.
– Nerve damage
What is the price of Immunoglobulin A Test Test in India?
The price of the Immunoglobulin A Test test in India ranges from Rs 1000 – 3000. It can vary with various locations around the country.
When will I get my results?

Is the CSF(Cerebrospinal Fluid) collection for the Immunoglobulin A test safe for the mother and the fetus?
