Baseline clinical laboratory results cannot definitively rule out toxin exposure because a normal set of labs at one point does not prove that exposure never occurred. The detectability of toxins depends on timing, dose, the specific toxin, and whether there are reliable biomarkers available in standard panels. Early after exposure, a person may be asymptomatic and have normal labs; some toxins cause effects that are not reflected in routine tests, or their lab abnormalities may appear only after organ injury develops. In addition, certain toxins require specialized assays beyond standard baseline tests to detect them. Because of these factors, a normal baseline result cannot reliably exclude prior or ongoing toxin exposure. Clinicians rely on history, exposure assessment, serial monitoring, and targeted testing when exposure is suspected.
