Aspergillosis - IgG antibody

Aspergillosis is an infection or allergic reaction caused by the fungus Aspergillus, which is commonly found in the environment, especially in soil, dust, compost, and decaying plant matter. While harmless for most healthy people, inhaling its spores can lead to serious illness in individuals with lung damage, compromised immunity, or prolonged exposure.

The Aspergillosis - IgG antibody test detects Aspergillus-specific IgG antibodies that typically develop weeks after infection onset. These antibodies, known as Aspergillus IgG precipitins, help indicate past or ongoing infections such as chronic pulmonary aspergillosis (CPA), aspergilloma (fungal ball), or subacute invasive aspergillosis. Elevated IgG levels may suggest previous or current exposure. Low or normal levels may also occur if the immune system cannot produce enough antibodies.

The doctor may recommend this test if there are symptoms suggestive of aspergillosis, such as persistent cough, chest pain, shortness of breath, or fever. The test is particularly advised for individuals with weakened immune systems (such as those with HIV/AIDS or undergoing organ transplantation), patients with chronic lung conditions like asthma or cystic fibrosis, and those on prolonged corticosteroid or immunosuppressant therapy. It may also be recommended to evaluate the risk of developing aspergillosis in high-exposure groups such as farmers or construction workers. Additionally, it is used to diagnose and monitor aspergillosis, assess the effectiveness of treatment, and track disease progression.

This test is often used alongside other diagnostic tools such as chest X-ray, CT scan, or sputum culture to confirm the presence of aspergillosis. It is important to note that a positive Aspergillus IgG test result alone does not confirm active infection; results should always be interpreted along with symptoms, imaging, and other laboratory findings to ensure an accurate diagnosis and guide effective treatment planning.

No special preparation is required for the Aspergillosis - IgG antibody test. Inform the doctor about all the medications and supplements currently being taken, as some of them may affect the test results, potentially requiring dosage adjustments or temporary discontinuation before the test.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
