Disease relevance of Point-of-Care Systems

  • To provide utilization of cardiac markers around the clock and facilitate the diagnostic work-up of patients with acute chest pain in the emergency room, a point-of-care system for quantitative troponin T and myoglobin testing in whole blood samples was developed [1].
 

High impact information on Point-of-Care Systems

  • In response to this need, we have developed a rapid platelet-function assay (RPFA), a point-of-care system that provides a quantitative measure of the competence of the GP IIb/IIIa receptor as reflected in the ability of platelets to agglutinate fibrinogen-coated beads [2].
  • During the 2-year study period, the total number of glucose assays performed in the clinical laboratories decreased by 22.2% concurrent with initiation of bedside testing [3].
  • BACKGROUND: Cerebral oximetry is a noninvasive bedside technology using near-infrared light to monitor cerebral oxygen saturation (Sco2) in an uncertain mixture of arteries, capillaries, and veins [4].
  • To document behavioral effects of interferon (IFN) with daily consecutive assessments we developed an easily administered procedure for bedside testing [5].
  • If the cTnT, measured either by the point-of-care system or a conventional lab analyzer, was >0.05 microg/L, then the chance of a cardiac event during the follow-up period was doubled (18% vs. 9%) [6].
