What does and equivocal TP-PA result mean?
Equivocal TP-PA – Specimens that show low reactivity, defined as either ( 1+) or () reactivity with the sensitized particles and (-) reactivity with the unsensitized particles, are repeated on the TP-PA. If the results of the repeat are the same, it is reported as Equivocal and are then tested by the FTA-ABS.
Equivocal TP-PA – Specimens that show low reactivity, defined as either ( 1+) or (±) reactivity with the sensitized particles and (-) reactivity with the unsensitized particles, are repeated on the TP-PA. If the results of the repeat are the same, it is reported as Equivocal and are then tested by the FTA-ABS.
