were “unknown agents.” For the sake of objectivity, we based our assumption on the aggregate of information for known pathogens rather than on “expert opinion.” Interestingly, however, the Council of Science and Technology’s “expert opinion” of the percentage of diarrheal illness due to foodborne transmission was 35% (1), nearly identical to the figure we developed. As noted in our article, pat...
Epidemiological investigations of maternal and child health may involve the collection of biological specimens, including cord blood and the placenta; however, the attitudes of pregnant women towards participation in the collection of biological specimens have been studied rarely. We evaluated attitudes towards collection and storage of biological specimens, and determined whether attitudes dif...
he increasing trend toward ambulatory care, home healthcare, nursing home care, and other alternate sites, has created variations in laboratory services and increased probability of medical errors. As an example, in order to increase laboratory volume, laboratory administrators have had to redirect blood collection services to outlying home and clinic settings via contracts with various physici...
INTRODUCTION: Analysis of urine is often used to detect the presence or determine the concentration of various biologically active compounds or xenobiotics. Urine has become the preferred specimen since many compounds can be detected for longer time periods in urine than in blood. Furthermore, urine collection does not require phlebotomy, and urine is typically an ample and stable sample. In mo...
The Delves micro-scale technique for blood lead analysis is an accurate method for screening capillary blood specimens, obtained by fingerstick, for lead intoxication. Results are affected by the age of cup, loop, and hollow-cathode tube and by the spatial relationship between optical tube and cup. Because the glass in many commercially available capillary tubes (used in specimen collection) ...
is started on a new antibiotic, always take an “antibiotic timeout” and reassess the patient after the first 48 to 72 hours of antimicrobial therapy to assure that the patient has responded to the antimicrobial therapy, as many of the uropathogens are multidrug-resistant. A urinalysis and culture should be collected based on the patient’s symptoms and not solely based on the urine’s characteris...
BACKGROUND Accurate quantification of mRNA in whole blood is made difficult by the simultaneous degradation of gene transcripts and unintended gene induction caused by sample handling or uncontrolled activation of coagulation. This study was designed to compare a new blood collection tube (PAXgene Blood RNA System) and a companion sample preparation reagent set with a traditional sample collect...
