Abstract Laboratory diagnostics (i.e., the total testing process) develops conventionally through a virtual loop, originally referred to as "the brain to brain cycle" by George Lundberg. Throughout this complex cycle, there is an inherent possibility that a mistake might occur. According to reliable data, preanalytical errors still account for nearly 60%-70% of all problems occurring in laborat...
The Standard PREanalytical Code (SPREC) was developed by the medical/clinical biobanking sector motivated by the need to harmonize biospecimen traceability in preanalytical processes and enable interconnectivity and interoperability between different biobanks, research consortia, and infrastructures. The clinical SPREC (01) consists of standard preanalytical variable options (7-code elements), ...
Telomeres are located at chromosome ends and their length (TL) has been associated with aging and human diseases such as cancer. Whole blood DNA is frequently used for TL measurements but the influence of preanalytical conditions and DNA isolation methods on TL quantification has not been thoroughly investigated. To evaluate potential preanalytical as well as methodological bias on TL, anonymiz...
Approaching clinical proteomics: current state and future fields of application in fluid proteomics.
The field of clinical proteomics offers opportunities to identify new disease biomarkers in body fluids, cells and tissues. These biomarkers can be used in clinical applications for diagnosis, stratification of patients for specific treatment, or therapy monitoring. New protein array formats and improved spectrometry technologies have brought these analyses to a level with potential for use in ...
Lyophilized cytosols prepared from calf uterus and human breast tumor tissue are commonly used to assess the reliability of routine steroid receptor assays. However, preanalytical error (sample preparation, storage, homogenization) cannot be detected in this way. Participating laboratories were asked to mail us all their receptor results obtained over a four-month interval, and to include some ...
A 12-year-old female patient presented with nonspecific symptoms including fatigue, fever, and headache persisting for approximately 4 months. Plasma ammonia was 230 μg/dL (135 μmol/L) (critical value >187 μg/dL or 110 μmol/L). The patient was referred to a pediatric emergency center for urgent evaluation of hyperammonemia. Plasma and urine amino acid testing was performed to investigate the po...
Point-of-care testing (POCT) represents one of the fastest growing segments of the diagnostics market. Although major advances have been made in the instrumentation and methods used for POCT, further development and enhancements appear to be necessary to meet the challenges presented by the difficult testing environments in which these devices are used. In addition, the varied experience and tr...
