61. Peripheral blood gene expression: it all boils down to the RNA collection tubes Full Text available with Trip Pro

Peripheral blood gene expression: it all boils down to the RNA collection tubes Gene expression profiling from peripheral blood is a valuable tool for biomarker discovery in clinical studies. Different whole blood RNA collection and processing methods are highly variable and might confound comparisons of results across studies. The main aim of the study was to compare genome-wide gene expression profiles obtained from the two widely used commercially available whole blood RNA collection systems (...) - PAXgene™ and Tempus™ tubes. Comparisons of present call rates, variances, correlations and influence of globin reduction across the two collection systems was performed using in vivo glucocorticoid stimulation in 24 peripheral blood samples from three individuals.RNA quality, yield and numbers of detected transcripts from the two RNA collection systems was comparable, with no significant differences between the tube types. Globin reduction resulted in a significant increase in present call rates (p

62. Effect of the size of evacuated blood collection tubes on total carbon dioxide concentration in equine plasma. (Abstract)

Effect of the size of evacuated blood collection tubes on total carbon dioxide concentration in equine plasma. To determine whether plasma total CO(2) concentrations would vary with the size of the evacuated tube used to collect blood samples.Randomized crossover study.Convenience sample of 20 healthy adult horses.Jugular venous blood was collected from horses in random order into 8 types of evacuated tubes: 2-mL glass, 2- or 3-mL plastic or plastic plasma separator, 4- or 6-mL plastic, and 10 (...) -mL glass or plastic. Total CO(2) concentrations in plasma were measured with a biochemistry analyzer. Data were analyzed via repeated-measures ANOVA and multivariate regression.The air volume-to-blood volume ratio was significantly higher and consequently, plasma total CO(2) concentration was significantly lower when blood was collected into 2-mL glass tubes and 2- or 3-mL plastic tubes than when the other 5 types of evacuated tubes were used. Concentrations in the other tube types were

Preanalytical Nonconformity Management Regarding Primary Tube Mixing in Brazil The multifaceted clinical laboratory process is divided in three essential phases: the preanalytical, analytical and postanalytical phase. Problems emerging from the preanalytical phase are responsible for more than 60% of laboratory errors. This report is aimed at highlighting and discussing nonconformity (e.g., nonstandardized procedures) in primary blood tube mixing immediately after blood collection (...) by venipuncture with evacuated tube systems.From January 2015 to December 2015, fifty different laboratory quality managers from Brazil were contacted to request their internal audit reports on nonconformity regarding primary blood tube mixing immediately after blood collection by venipuncture performed using evacuated tube systems.A minority of internal audits (i.e., 4%) concluded that evacuated blood tubes were not accurately mixed after collection, whereas more than half of them reported that evacuated

66. Evacuated blood-collection tubes--the backflow hazard. Full Text available with Trip Pro

Evacuated blood-collection tubes--the backflow hazard. Five cases of nosocomial infection caused by Serratia marcescens were traced to backflow of blood from nonsterile evacuated blood-collection tubes. The mechanism of backflow was investigated theoretically and the conditions were determined under which backflow can occur. The theory was confirmed by experiments conducted on a simulated venous system and by measurements of the venous pressure in the brachial vein of a patient during (...) application and removal of a tourniquet. Various possible solutions to the backflow hazard include strict adherence to correct venipuncture technique, sterilization of all blood-collection tubes, improvement of the vacuum in the tubes and incorporation of a check valve into the system.

69. Prenatal Screening for Down Syndrome, Trisomy 18, and Open Neural Tube Defect

trimester ultrasound 2 are some of the options available for prenatal genetic screening? The risks for fetal Down syndrome, trisomy 18, and open neural tube defects (ONTDs) are calculated using a combination of variables which may include: biochemical serum markers collected from blood work, maternal age, maternal ethnicity, maternal weight, maternal diabetic status, maternal smoking, and, if available, nuchal translucency (NT) ultrasound measurement? There are four different screening tests: SIPS, IPS (...) sent to the Prenatal Biochemistry Laboratory at Children’s and Women’s Health Centre (C&W) for analysis? IPS involves measurement of first trimester serum PAPP-A and a nuchal translucency (NT) ultrasound and second trimester serum quad markers (AFP , uE3, hCG and inhibin-A)? The blood tests are collected as per the timing for SIPS and the NT measurement is done between 11 – 13 +6 weeks (best at 12 – 13 +3 weeks)? Given that NT must be performed by a certified sonographer or sonologist, this test

An absence of urine, presence of blood in the collection bag, or flank pain may indicate that the tube is blocked. 24 If blockage is suspected it was recommended that nephrostomy tubes be irrigated or flushed using gentle force with normal saline or sterile water using sterile or aseptic technique. 4,6,9,10,24 Two documents stated that hand washing before and after flushing the nephrostomy tube is essential and sterile gloves should be worn. 6,24 Four guidelines recommend (...)

Fibrinogen alpha C chain 5.9 kDa fragment (FIC5.9), a biomarker for various pathological conditions, is produced in post-blood collection by fibrinolysis and coagulation factors Fibrinogen alpha C chain 5.9 kDa fragment (FIC5.9) is a new serum biomarker for chronic hepatitis that was discovered by proteomics analysis. Previous studies have shown that FIC5.9 is derived from the C-terminal region of fibrinogen alpha chain and the serum levels of FIC5.9 decrease in chronic hepatitis. It also have (...) been reported that FIC5.9 cannot be detected in the blood stream of the systemic circulation and it is released from fibrinogen during blood clotting in collecting tube. However, the mechanism of FIC5.9 releasing from fibrinogen is unclear.We formulated a hypothesis that FIC5.9 is released by enzymes that are activated by post-blood collection and may be coagulation and fibrinolysis factors. In this study, we analyzed the mechanisms of FIC5.9 releasing from fibrinogen in healthy blood.Our analysis
