What Is IgG in Nasal Fluid Used For?

Doctors may order this test to evaluate immune function in the nasal passages, particularly in conditions like chronic sinusitis, recurrent infections, or immune-related disorders. It can also help monitor immune responses in certain allergic or inflammatory conditions.

How Is the Test Performed?

A small sample of nasal fluid is collected using a sterile swab or similar device. The sample is then sent to a lab for analysis to measure IgG levels.

What Does a Result Mean?

Results may indicate normal immune activity in nasal secretions or could suggest an abnormal immune response, such as excessive inflammation or infection. Interpretation depends on clinical context and other test results.

Common Conditions Monitored

This test may be used in cases of chronic sinusitis, recurrent nasal infections, or immune deficiencies affecting the respiratory tract. It can also support research or diagnostic evaluations in allergic or autoimmune conditions.

Clinical interpretation
