This is the requirement that the observations be statistically independent. We present a proposal for a new approach to statistical quality control that removes this difficulty. We propose to replace the current single control chart of raw Q/C data with two charts: (a) a common cause chart, representing a Box-Jenkins ARIMA time-series model of any underlying persisting nonrandomness in the process, and (b) a special cause chart of the residuals from the above model, which, being free of such persisting nonrandomness, fulfills the criteria for use of the standard Levey-Jennings plotting format and standard control rules. We provide a comparison of the performance of our proposed approach with that of current practice.

There are several surface matrices, named proteinChips, available for analyzing a particular analyte or a subset of biomolecules in biological samples. Each proteinChip has a unique surface property suitable for fractionation of a specific group of molecules. This article demonstrates the application of SELDI-TOF for the analysis of a cleaved peptide (Mr7739 daltons) from von Willebrand Factor by a metalloproteinase, ADAMTS13. Deficiency of ADAMTS13 is a known primary risk factor for the devastating hematological disorder, Thrombotic thrombocytopenic purpura (TTP). Rapid determination of ADAMTS13 activity helps clinicians tremendously in making the correct diagnosis and initiating timely therapy. Most patients with TTP are ...

Both glucose meters correlated significantly with the Ektachem results. A significant positive bias was found for the Glucoscan compared with Ektachem, not found with the Accu-Check II. The Accu-Check performed better than the Glucoscan at venous plasma glucose levels less than 1 g/L. The mean error of Glucoscan determinations was significantly greater and biased positive when the measurement was performed within 4 hours of eating, whereas no such effect was seen with Accu-Check error. Multiple regression analysis revealed that the Glucoscan measurement was independently influenced by both venous plasma glucose and prandial state, whereas the Accu-Check II measurement was not dependent on either variable. The within-run precision for both glucose meters were comparable.

This article outlines major US legal/regulatory issues and requirements relevant to accreditation of toxicology laboratories (state and local regulations are not covered in any depth). The most fundamental regulatory distinction involves the purposes for which the laboratory operates: clinical versus nonclinical. The applicable regulations and the requirements and options for operations depend most basically on this consideration, with clinical toxicology laboratories being directly subject to federal law including mandated options for accreditation and forensic toxicology laboratories being subject to degrees of voluntary or state government–required accreditation.

A new desktop application has been developed with the aim of enabling more efficient and accurate gel analysis by clinical pathologists. This tool gives the pathologists the ability to perform their analysis conveniently from anywhere on the OSUMC network along with the aid of numerical analysis algorithms, image enhancement techniques, and access to historical PEP results for the given patient.

The "gifts" typically aren't as luxurious in the clinical laboratory, but even so, is any vendor freebie too much?

Indeed, a major impetus for automating clinical laboratories has always been the opportunity it presents to simultaneously reduce cost and improve quality of operations by decreasing human error. But merely automating these processes is not enough. To the extent that introduction of these systems results in operators having less practice in dealing with unexpected events or becoming deskilled in problemsolving, however new kinds of error will likely appear. Clinical laboratories could potentially benefit by integrating findings on human error from modern behavioral science into their operations. Fully understanding human error requires a deep understanding of human information processing and cognition. Predicting and preventing negative consequences requires application of this understanding to laboratory operations. Although the occurrence of a particular error at a particular instant cannot be abso...
