Recommendations for the frequency of ordering laboratory testing

Abstract: Laboratory testing is crucial for the successful medical treatment of many patients. Laboratory tests should neither be ordered too infrequently nor too frequently (in the form of repeat testing). These recommendations summarize the intervals for repeat testing based on studies, pathophysiology and consensus, in regard to both the time intervals between two tests and the additional criteria for the repeat testing. These recommendations are complemented by general principles for the indication and testing frequ… Show more

“…Harmonisierung wird vom Clinical and Laboratory Standards Institute (CLSI) definiert als "the process of recognizing, understanding, and explaining differences while taking steps to achieve uniformity of results, or at a minimum, a means of conversion of results such that different groups can use the data obtained from assays interchangeably" [9]. Die Harmonisierung im Bereich der Labormedizin ist vielfältig und reicht von der Prä-Präanalytik wie Terminologie, Parameterprofilen [10], Untersuchungsintervallen [11] über die Präanalytik wie Abnahmezeiten, Patientenvorbereitung, Probentransport und Probenlagerung über die Analytik wie Kontrolle der Probenqualität und den analytischen Kriterien (Methode, Kalibrator, Qualitätssicherung) bis hin zur Postanalytik wie Einheiten und Datenformaten, Referenzintervallen und Entscheidungswerten [12].…”

“…On top of this hierarchy are assessments of the effect of analytical performance on clinical decision-making (outcome studies), second professional recommendations, third quality specifications laid down by regulation or external quality assessment scheme (EQAS) organizers and last, published data on the state-of-the-art. It is not surprising, that most work for setting quality specifications even lower in hierarchy than HTA or the good use of laboratory medicine (GULM) has been done so far on 'simple chemical tests' such as electrolytes, glucose, or Hb A1c [4] leaving wide areas of laboratory medicine without widely-accepted recommendations [5] and the practical use of these recommendations has not reached the whole area of laboratory medicine due to numerous reasons, most of them not under sufficient control of the people working in the laboratory.…”

“…However, for some tests in fact extensive preanalytical precautions (such as in regard of timing, food intake, body posture, physical activity and drug intake) can minimize these variation. In other tests, standardization, traceability, and improvement of the reagents used should be the focus that can diminish the bias between different tests of different vendors [5,17]. The discussion is still open as to whether different analytical performance standards might be acceptable between central laboratory tests and point of care tests such as in the determination of cardiac peptides or creatinine [18,19].…”
