Abstract
Measurement of biological signals directly at the patient (point-of-care testing, POCT) is an established standard in emergency medicine when test results are needed quickly and within a reliable time frame or if external testing requires a disproportionate effort. Currently, the rapid test for β-HCG in urine and POCT measurement of lactate, blood gases, cardiac tropinin, haemoglobin, and hematocrit are well established in emergency medicine. POCT of copeptin, fatty acid-binding proteins (FABP), procalcitonin, coagulation values, natriuretic peptides, D-dimer, and toxicological substances are of future interest. In this article, the appropriate use of point-of-care testing in prehospital emergency medicine is discussed. Application of POCT is dependent of the underlying conditions, the availability of appropriate devices, and of suitable reference methods in a central laboratory. In addition, economical and quality aspects play an important role. In emergency departments, POCT is currently developing into a standard measuring method for a number of markers because hospital laboratories are increasingly being merged and consequently reduce their emergency-analytic services. In countries with a high density of hospitals, however, preclinical POCT should be reduced to the minimum necessary.
