The Toxo Gondii -IgG test helps in assessing and determining if a person has a current active toxoplasmosis infection or if the person had any toxoplasmosis infection in the past. The Toxo Gondii IgG test can be conducted by using a blood sample or a sample of CSF(Cerebrospinal Fluid). In the case of pregnant women, a sample of amniotic fluid can also be collected for carrying out the test.

– 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 Toxo Gondii IgG test.

In the case of infants, the blood sample is collected from the heels of the infant with a simple pinprick.
 

What is the procedure of the CSF(Cerebrospinal Fluid) test for the Toxo Gondii IgG 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.

– 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– You need to stay still as the cerebrospinal fluid is being withdrawn.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 headaches afterward.

What is the procedure of the amniotic fluid sample collection in pregnant women for the Toxo Gondii IgG test?

The procedure of collection of the amniotic fluid and testing it is called amniocentesis. The procedure for collecting the amniotic fluid sample is as follows:

– Position the patient properly.
– Sterilize the exposed area of the abdomen.
– Use an anesthetic to avoid any kind of pain.
– Then inject the ultrasound-guided hollow needle through the anterior abdominal wall into the amniotic cavity.
– Draw a sample of 15 to 20ml of amniotic fluid.
– Send the sample to the laboratory for the Toxo Gondii IgG test.

Is the procedure of the Toxo Gondii IgG Test painful?

There’s no pain associated with the collection of the blood sample. A person might feel a pin pricking sensation for a very brief moment after the test. The pain wears off within a few hours.

– 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 the Toxo Gondii IgG CSF(Cerebrospinal Fluid) Test?

There are a few risks which are associated with the CSF(Cerebrospinal Fluid) collection. Some of the risks are, as listed below:

– 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.
– Infection.

Positive NegativeEarly infection. In the case of a newborn, it indicates congenital infection
Positive PositiveCurrent infection or chronic infection. It can also indicate reactivation.
