Schistosoma IgG Antibody (Serum) – Parasite Screening
This blood test checks for antibodies to the parasite *Schistosoma*, which can cause infections like schistosomiasis. Antibodies may appear if you’ve been exposed to the parasite’s eggs or larvae.
["Helps detect past exposure to a parasitic infection that may affect your skin, bladder, or other organs."]

What This Test Measures
The test detects *Schistosoma IgG*, a type of antibody produced by your immune system in response to exposure to the parasite’s eggs or larvae. These antibodies can linger in your blood even after the infection has cleared. This test is not used to diagnose an active infection but rather to identify prior exposure.
Why You Might Need This Test
Your healthcare provider may recommend this test if you’ve lived in or traveled to regions with high schistosomiasis risk (e.g., parts of Africa, South America, or Asia) or if you have symptoms like skin rashes, urinary issues, or unexplained fatigue that could be linked to past exposure.
What to Expect Before the Test
No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. The process takes about 5 minutes, and you may feel slight discomfort.
What to Expect After the Test
After the blood draw, apply gentle pressure to the site to stop bleeding. You can resume normal activities immediately. Rarely, you might experience mild bruising or soreness.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate past exposure to *Schistosoma*, which can lead to chronic inflammation or organ damage over time. However, this test alone cannot confirm an active infection. If symptoms persist, further testing or medical evaluation may be needed to assess potential complications.
Short name
