Diagnosis of infectious diarrhea and identification of antimicrobial resistance is performed using a stool culture with subsequent antibiotic sensitivity testing. It requires a minimum of 2 days and maximum of several weeks to culture gastrointestinal pathogens. The sensitivity (true positive) and specificity (true negative) rates for stool culture vary by pathogen, although a number of human pathogens can not be cultured. For culture-positive samples, antimicrobial resistance testing takes an additional 12–24 hours to perform. Current point of care molecular diagnostic tests can identify<unk>  and antimicrobial resistance in the identified strains much faster than culture and sensitivity testing. Microarray-based platforms can identify<unk>  and AMR genes in two hours or less with high sensitivity and specificity, but the size of the test panel (i.e., total pathogens and AMR genes) is limited. Newer metagenomics-based infectious disease diagnostic platforms are currently being developed to overcome the various limitations of culture and all currently available molecular diagnostic technologies.
