Process Improvement in Phlebotomy
This study has two main objectives. First, the phlebotomy process at the St. Catharines Site of the Niagara Health System is investigated, which starts when an order for a blood test is placed, and ends when the specimen arrives at the lab. The performance measurement is the flow time of the …

Development, implementation and impact of Phlebotomy training on blood sample rejection and Phlebotomy knowledge of primary health care workers at selected primary health care facilities in Cape Town: a quasi-experimental study design
… sample rejection at four PHCFs pre and post phlebotomy training. The secondary objective was to determine whether phlebotomy training improved knowledge amongst primary health care providers (HCPs) and to develop a tool for blood sample acceptability. Study Setting: Two Community Health …

Erythropoietin for the Treatment of Porphyria Cutanea Tarda in End Stage Renal Disease
… which prevents treatment of these patients by phlebotomy. Anemia in these patients results largely from decreased production of erythropoietin by the diseased kidneys. Erythropoietin administration can mobilize excess iron, correct anemia and support phlebotomy in these patients. This study …

Identification and reduction of pre-analytical errors in clinical chemistry through expert advice
… frequently the results of human mistakes during phlebotomy practice. Therefore to reduce these errors the pre-analytical phase of the TTP must be prioritised. Study objective: To investigate the sources of pre-analytical errors in the TTP, categorize these errors in order to identify the error …

Analysis of a diagnostics firm's pre-analytical processes
… late-release challenges through an analysis of phlebotomy services, courier route planning, and specimen accessioning to find precisely the source and cause of challenges preventing Quest from achieving their turnaround time goals. Prior to this research, Quest hypothesized that their logistics …

Reducing Turnaround Time of Clinical Laboratory Analysis Through Use of Efficient Blood Collection Techniques
… and the volume of blood specimen required during phlebotomy may provide the resolution to a more efficient process. The purpose of this paper is to demonstrate effective laboratory blood collection processes and how streamlining these methods in an efficient manner can reduce analytical turnaround …

Depth and Size Limits for the Visibility of Veins Using the VeinViewer Imaging System
… to access the veins in patients at hospitals or phlebotomy centers. It is important to minimize the discomfort associated with sticking needles in the patient more than once and most often, necessary to find an appropriate vein within few minutes. However, problems involved in accessing veins in …

Mechanistic and Clinical Studies of Platelet Rich Plasma: A Simple Clinical Method for Enhancing Bone and Soft Tissue Healing
… blood is drawn from the patient by conventional phlebotomy techniques and then centrifuged with the formation of a distinct middle layer that contains platelets and white blood cells (WBCs). This layer of platelets and WBCs is then placed into the surgical site to enable faster and more …

Disease mechanisms and markers of progression in cerebral small vessel disease
… of patients with SVD undergoing PET-MRI imaging, phlebotomy and neuropsychometric testing. Results <br>WMHs typically expand at 2.50 ± 3.02 cc/year in patients with SVD and this is significantly more likely in patients with hypertension and who currently smoke. I found only 12/417 participants …

Hinokitiol restores hemoglobinization and mitigates neurodegeneration in animals by re-establishing iron homeostasis
… FD patients are still treated with venesection/phlebotomy, which fails to address the underlying issue. Due to the unique nature of iron misdistribution disorder, for a molecule to successfully treat this disorder, it must be able to perform iron redistribution until iron homeostasis is reached. …

The role of erythropoietin in the pathophysiology of anemia associated with trypanosomiasis
… in the kidney of an anemic calf (created by phlebotomy). Epo mRNA was also detected in the spleen from the anemic calf and the spleen of a 19 week old bovine fetus using quantitative PCR assay. The bovine Epo cDNA was expressed in three different expression systems: bacterial, vaccinia virus …

Modelling the pathophysiology of schizophrenia and methamphetamine-induced psychosis: A structural magnetic resonance imaging and cytokine study
… structural magnetic resonance imaging (MRI) and phlebotomy. Symptom severity was assessed with the positive and negative symptom scales (PANSS). Volumes of the amygdala, hippocampus and basal ganglia and frontal cortical thickness and surface area were processed with FreeSurfer. TNF-α, IL-1β, -8, …

Cellular immune ontogeny and birth transcriptome in HIV-exposed uninfected infants
… ex vivo or after re-stimulation within 1 hour of phlebotomy with BCG, Tetanus Toxoid (TT), Bordetella pertussis (BP) antigens and Phytohemagglutinin (PHA). Multi-parameter flow cytometry was used to measure batched whole blood samples for (i) markers of T cell regulation and activation directly ex …
