Chlamydia psittaci IgG antibody (serum/plasma) by immunoassay

What Does This Test Measure?

The test detects IgG antibodies, a type of immune protein your body makes after exposure to *Chlamydia psittaci*. These antibodies stay in your system for years, even after the infection has cleared. This test is not used to diagnose an active infection but can help identify past exposure.

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like persistent cough, fever, or respiratory issues—especially if you’ve been exposed to birds or bird droppings. It’s also used in occupational or travel-related risk assessments.

How Is the Test Performed?

A blood sample is taken from a vein in your arm. The blood is processed to separate serum or plasma, which is then tested for IgG antibodies using an immunoassay method. This method detects the presence of antibodies without measuring their exact concentration.

What Are Common Symptoms?

Symptoms of *Chlamydia psittaci* infection (if active) may include flu-like symptoms (fever, chills), cough, shortness of breath, or fatigue. However, many people may not have noticeable symptoms. This test alone cannot confirm an active infection—it only shows past exposure.
