negative: <9.0
equivocal: <9
positive: >11

B pertussis IgM      0.7
range is same
as above

B pertussis IgA      3.0

My question is do I currently have pertussis? I have all the signs and symptoms. I had pertussis as a baby and I am now 61. I believe I am in the second stage of pertussis now. Thank you

Optional Information:
Female , Age: 61

Already Tried:

Modern serologic techniques, such as enzyme-linked immunosorbent assay (ELISA), have been used to detect IgG, IgM, IgA antibodies to both whole B pertussis cells and certain isolated components. In accordance with other serologic methods, seroconversion could be observed only 2 to 4 weeks after the onset of the disease. The detection of specific IgA and IgM antibodies, however, is indicative of recent infection and is useful for the differential diagnosis of pertussiform syndromes of longer duration. Detection of IgG antibody indicates past infection.

So what you are saying is I did in fact have pertussis recently and am now in the second stage of it as it resolves?
