118cc-1-3-117 Full text Multicenter studies require a high degree of standardization to guarantee the demanded quality standard. One potential source of error is incorrect blood specimen collection in the different study centers, especially if different types of anticoagulants or specific inhibitors (eg cyclooxygenase inhibitors for prostaglandin determinations) are used. To avoid such problems...

background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...

Complete blood protein profiles of 4 different blood sample collection methods (EDTA-, heparin- and citrate plasma and serum) were investigated and the data presented herein is an extension of the research article in Ilies et al. [1]. Specimens were depleted of 6 highly abundant proteins and protein profiling was assessed by nano-LC UDMSE. Exhaustive protein sets and protein abundances before a...

Blood specimens collected for culture by using the high-volume resin-based BACTEC system over an 18-month period at the Seattle Veterans Administration Center were examined in this study. Of 7,783 cultures obtained, 624 were classified as true positives. Patients in this group had between 20 and 60 ml of blood drawn per culture and separated into 10-ml aliquots for incubation. Analysis of the r...
