Processing of one biological sample to yield multiple biomarker results allows for POCT testing to be done for patients who may have conditions that require the confirmation of multiple biomarkers and tests before diagnosis (e.g. many types of cancers[1]). xPOCT has important emerging applications in resource-limited settings, (e.g. in the developing countries, in doctor's practices, or at home by non experts) xPOCT has recently become more important for in vitro diagnostics.[2]
