point-of-care genetic testing point-of-care genetic testing point-of-care genetic testing identifies variations in the genetic sequence at the bedside – enabling clinicians to react and alter therapy based upon the results. traditional genetic testing involves the analysis of dna in order to detect genotypes related to a heritable disease or phenotype of interest for clinical purposes. however, current testing methods require days to weeks before results are available limiting the clinical applicability of genetic testing in a number of circumstances. recently, the first point-of-care genetic test in medicine was demonstrated to be effective in identifying cyp2c19*2 carriers allowing tailoring of anti-platelet regimens to reduce high on treatment platelet reactivity. in the rapid gene study, drs. jason roberts and derek so from the university of ottawa heart institute validated a pharmacogenomics approach in patients undergoing percutaneous coronary intervention for acute coronary syndrome or stable coronary artery disease. this study is the first in medicine to incorporate point-of-care testing with genetics into routine clinical care and decision making.
