Chlamydia psittaci antibody, IgG (Serum/Plasma)

What This Test Measures

The test identifies IgG antibodies against *Chlamydia psittaci*, a bacterium that may be transmitted through contact with infected birds (e.g., parrots, pigeons) or contaminated environments. These antibodies indicate your body has recognized and fought the infection, but they do not confirm an active illness at the time of testing.

How the Test Works

Your blood sample is analyzed to detect IgG antibodies using an immunoassay method. This helps determine if your immune system has encountered *Chlamydia psittaci* previously, though active infection would require additional diagnostic testing.

Why It Might Be Ordered

A healthcare provider may recommend this test if you’ve had recent exposure to birds, symptoms of respiratory illness (e.g., fever, cough), or if you’re evaluating for atypical infections in certain high-risk settings (e.g., poultry workers, bird owners).

What to Expect Before Testing

No special preparation is needed. Bring your medical records or recent exposure history if requested. Avoid alcohol 24 hours before testing, as it may affect blood chemistry results indirectly.
