Bordetella Pertussis Toxin IgG At

The Bordetella Pertussis Toxin IgG At test is used in laboratories to detect specific antibodies in the blood, which can signal a recent infection with the Bordetella pertussis bacterium. This bacterium causes whooping cough, an acute respiratory illness that continues to be one of the leading preventable causes of death globally, despite widespread childhood vaccination programs.

When is this test necessary?

This test is particularly helpful in diagnosing a recent Bordetella pertussis infection in patients who have had whooping cough-like symptoms for two weeks or more. It is not recommended for newborns, young infants, or children aged 4 to 7 years, as the standard childhood vaccination schedule may affect the interpretation of the results.

How is the Bordetella Pertussis Toxin IgG At test conducted?

The test involves drawing blood from a vein, which is then analyzed in a laboratory. At IntroLab in Belgrade, we use the ELISA method to detect antibodies in the patient’s serum. The blood draw is quick and entirely painless.

What do the results indicate?

The outcomes of the Bordetella Pertussis Toxin IgG antibody test can be categorized as:

• Negative (less than 40 IU/mL)
• Borderline (between 40 and 100 IU/mL)
• Positive (greater than 100 IU/mL)

A negative result suggests that no IgG antibodies to pertussis toxin were detected. If the result is borderline, it is advisable to retest in 10 to 14 days. A positive result indicates the presence of IgG antibodies to pertussis toxin, which may suggest a recent infection or recent vaccination.

Our lab employs highly accurate methods for the Bordetella Pertussis Toxin IgG At test, providing reliable results for our patients. The high quality of the antigens used in the ELISA test ensures the test’s specificity.
