Multiplexed ELISA screening assay for nine paralytic shellfish toxins in human plasma.

Paralytic shellfish poisoning is a lethal syndrome that can develop in humans who consume shellfish contaminated with paralytic shellfish toxins. These toxins have a short half-life in the human body, so a rapid diagnostic assessment of the poisoning is necessary. In this paper, we have developed and validated a rapid ELISA screening assay using anti-saxitoxin antibodies to screen nine toxins: saxitoxin; decarbamoyl saxitoxin; gonyautoxin 2,3; decarbamoyl GTX 2,3; neosaxitoxin; and gonyautoxin 1,4, in human plasma with lower limits of detection of 0.
