21. Pseudothrombocytopenia with multiple anticoagulant sample collection tubes (PubMed)

Pseudothrombocytopenia with multiple anticoagulant sample collection tubes The knowledge of pseudothrombocytopenia (PTCP) is important for the accuracy of a clinical assessment and for avoiding unnecessary treatment. An elderly patient was hospitalized with left lung pneumonia. Severe thrombocytopenia [platelet (PLT) number: 18 × 109/L] without any clinical bleeding was found in ethylenediaminetetraacetic acid blood collection tube. PLT measurement was repeated in various anticoagulant [sodium (...) citrate, lithium heparin, disodium oxalate, hirudin, and magnesium sulfate (Mg-sulfate)] sample collection tubes and all of them showed thrombocytopenia except with Mg-sulfate. To the best of our knowledge, PTCP with five anticoagulant sample collection tubes has not been reported earlier.

23. Electronic patient identification for sample labeling reduces wrong blood in tube errors. (PubMed)

Electronic patient identification for sample labeling reduces wrong blood in tube errors. Wrong blood in tube (WBIT) errors are a preventable cause of ABO-mismatched RBC transfusions. Electronic patient identification systems (e.g., scanning a patient's wristband barcode before pretransfusion sample collection) are thought to reduce WBIT errors, but the effectiveness of these systems is unclear.Part 1: Using retrospective data, we compared pretransfusion sample WBIT rates at hospitals using (...) manual patient identification (n = 16 sites; >1.6 million samples) with WBIT rates at hospitals using electronic patient identification for some or all sample collections (n = 4 sites; >0.5 million samples). Also, we compared WBIT rates after implementation of electronic patient identification with preimplementation WBIT rates. Causes and frequencies of WBIT errors were evaluated at each site. Part 2: Transfusion service laboratories (n = 18) prospectively typed mislabeled (rejected) samples (n

24. Compare the Q-Cup With Other Umbilical Cord Blood Collection Techniques

by (Responsible Party): Michael Schaffer, Texas Tech University Health Sciences Center, El Paso Study Details Study Description Go to Brief Summary: Currently there is no standardized method of collecting and transferring umbilical cord blood to laboratory vacuum tubes. Current methods are messy and may require needles to draw the blood presenting risk of blood exposure and percutaneous injury to obstetrical personnel. A safer, more efficient method of collecting cord blood is needed. The investigators (...) propose to use the Q-Cup technology for collecting cord blood. The Q-Cup device is a two-piece injection molded blood collection and transfer device that enables safe and easy collection of blood from the newborn's umbilical cord and readily transfers the blood into a laboratory vacuum tube. The device consists of a collection cup with a wide opening to easily collect blood from the umbilical cord and a guide tube with a recessed needle which is attached to the collection cup. The operator is enabled

Collection of non-meconium stool on fecal occult blood cards is an effective method for fecal microbiota studies in infants Effective methods are needed to collect fecal samples from children for large-scale microbiota studies. Stool collected on fecal occult blood test (FOBT) cards that can be mailed provides an effective solution; however, the quality of sequencing resulting from this method is unknown. The aim of this study is to compare microbiota metrics of 16S ribosomal RNA (rRNA) gene (...) sequencing from stool and meconium collected on FOBT cards with stool collected in an Eppendorf tube (ET) under different conditions.Eight stool samples from children in diapers aged 0 month-2 years and three meconium samples were collected and stored as follows: (1) ≤ 2 days at room temperature (RT) in an ET, (2) 7 days at - 80 °C in an ET, (3) 3-5 days at RT on a FOBT card, (4) 7 days at RT on a FOBT card, and (5) 7 days at - 80 °C on a FOBT card.

Suitability of Becton Dickinson Vacutainer rapid serum tube for collecting and storing blood samples for antibiotic and anticonvulsant drug monitoring. To investigate the suitability of newly developed Becton Dickinson Vacutainer rapid serum tube (RST) for therapeutic drug monitoring of antibiotics and anticonvulsants.Two pools of citrated whole blood were created by spiking high and low concentrations of gentamicin, vancomycin, phenytoin, lamotrigine and carbamazepine. After recalcification (...) with 15 mmol/L calcium chloride, spiked whole blood was added into four different Becton Dickinson blood collection tubes: RST, serum separator tube, red top tube and polyethylene plain tube. Serum aliquots were collected at baseline (0 h), 2 h, 24 h, day 3 and day 7. Drug concentrations were measured in batch by HPLC and the Architect c8000.Gentamicin and vancomycin concentrations were stable up to 7 days in all 4 blood collection tubes.

to a significant reduction in blood culture contamination rates. This technique is based on the assumption that the skin plug aspirated during venipuncture is a major source of contaminating bacteria. One such diversion method is aspirating the first blood volume into a blood collection tube. It has, however, been suggested that regular blood collection tubes carry contaminants from the tube's stopper into the blood cultures drawn afterwards, thereby increasing contamination rates. The aim of this trial (...) is to examine the effect of aspirating the first blood volume into a regular blood collection tube on blood culture contamination rate.

32. Gene expression differences between PAXgene and Tempus blood RNA tubes are highly reproducible between independent samples and biobanks (PubMed)

Gene expression differences between PAXgene and Tempus blood RNA tubes are highly reproducible between independent samples and biobanks Gene expression profiling from blood is sensitive to technology choices. For example, the main blood RNA collection systems-the PAXgene and Tempus tubes-differently influence RNA expression signatures. The aim of this study was to establish a common RNA isolation protocol for these two systems and investigate if it could reduce the differences in gene (...) expression between them.We collected identical blood samples on the PAXgene and Tempus systems and retrieved blood samples from two independent biobanks-NOWAC and HUNT3-which are based on PAXgene and Tempus, respectively. High-quality RNA was extracted from both sampling systems by using their original protocols and our common modified protocol, and were profiled on Illumina microarrays. Regardless of the protocol used, we found most of the measured transcripts to be differently affected by the two

33. Variable temporal sampling and tube current modulation for myocardial blood flow estimation from dose-reduced dynamic computed tomography (PubMed)

Variable temporal sampling and tube current modulation for myocardial blood flow estimation from dose-reduced dynamic computed tomography Quantification of myocardial blood flow (MBF) can aid in the diagnosis and treatment of coronary artery disease. However, there are no widely accepted clinical methods for estimating MBF. Dynamic cardiac perfusion computed tomography (CT) holds the promise of providing a quick and easy method to measure MBF quantitatively. However, the need for repeated scans (...) the tube current and/or sampling intervals can yield more accurate MBF estimates for a given dose. Specifically, we try to minimize the dose and obtain the most accurate MBF estimate by addressing the following questions: when in the TAC should the CT data be collected and at what tube current(s)? We hypothesize that increasing the sampling rate and/or tube current during the time frames when the myocardial CT number is most sensitive to the flow rate, while reducing them elsewhere, can achieve better
