Toxicity Screening Panel for Giardia lamblia (Serum/Plasma)

What This Test Measures

Giardia lamblia is a microscopic parasite that can live in your intestines, often causing symptoms like stomach cramps, diarrhea, or nausea. This test detects antibodies (proteins) your body makes when it fights off the infection. These antibodies appear in your blood after exposure and can indicate past or current infection.

How the Test Works

Blood is drawn from a vein, usually in your arm. The sample is then tested using an immunoassay method to identify specific antibodies linked to Giardia. The test is qualitative, meaning it only tells whether antibodies are present, not their exact level.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, stomach pain, or bloating—especially if you’ve traveled to areas with poor sanitation or have had recent contact with someone who has Giardia. It’s also used in screening for travelers or those in settings like daycare centers where infections spread.

What to Expect Before or After the Test

No special preparation is needed. You may feel slight discomfort from the needle, but it usually goes away quickly. If you’re on blood thinners or have a history of bleeding, let your provider know. Results are typically ready within a few days, but timing may vary.
