Euro Diagnostica recommends the highly acclaimed and customer proven Pertusscan TRO. This diagnostic package allows for individual testing of IgG or IgA against PT or FHA which further strengthen the diagnostic accuracy in specific groups such as the elderly or previously immunized individuals.
Pertusscan TRO is an enzyme linked immuno sorbent assay (ELISA) for the detection of IgA and IgG antibodies against Bordetella Pertussis filamentous hemagglutinin (FHA) and pertussis toxin (PT) in serum or plasma specimens.
Elevated OD value of IgG to PT (³1.0) with or without elevated IgG to FHA indicates previous infection or immunization and can be used as an indicator of immunity to the disease. In patients older than 60 years of age an isolated IgA rise to FHA is often seen during current infection. Un-immunized children, especially infants may show poor response to FHA but have high rises to PT.« Back
