Urine Drug Screening - Is it All 'Easy', or What are the Challenges?

An article by Prof. Dr. med. Werner Steimer, INSTAND EQAS/PT Expert Drug Screening and Pharmacology: INSTAND has long offered a range of well-established EQAS/PT for drug analysis, particularly in urine. Depending on the reported results, these interlaboratory tests are evaluated qualitatively and/or quantitatively. One might think that qualitative interlaboratory tests in particular are easy to evaluate and interpret, following the principle that positive is positive and negative is negative. However, this is a fallacy, or rather a dangerous oversimplification.

Analysis of the suitability of the whole blood beads model as control material in glucose point-of-care testing for external quality assessment schemes

External quality assessment (EQA) for point-of-care testing (POCT) of glucose has faced challenges due to the lack of high-quality, suitable, and practical control materials for evaluating measurement accuracy. Current EQA studies predominantly use glucose measurements in processed plasma. However, it is essential to note that devices designed for POCT glucose measurement are typically intended for use with capillary blood. To solve this problem, INSTAND e.V. recently introduced an innovative concept for control materials in POCT glucose measurement: the Whole Blood Beads (WBB) model, which enables EQA studies in whole blood.

THE HETEROGENEITY AND COMPLEXITY IN THE DETERMINATION OF HEMOGLOBIN CONCENTRATION IN SOME HEMATOLOGY EQA SCHEMES OF INSTAND e.V.

An article by INSTAND EQA Scheme Expert Dr. med. Benedikt Lohr: The determination of the CBC is one of the most common laboratory medical examinations. The Hb concentration included in the CBC is the product of the erythrocyte count and the Hb content of the erythrocytes. The hemoglobin content per unit of blood volume is measured, so the result depends on the plasma volume.
