BACKGROUND 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 af...

Venipuncture is one of the most commonly done medical procedures. We report a unique case of a 23-year-old young male who presented with features suggestive of inflammatory arthritis. The symptoms, which initially started on the right side, also involved the other side after a few weeks. Although the patient's symptoms and signs were simulating inflammatory arthritis, he had atypical features l...

We examined the sensitive assay for carboxyhemoglobin based on reaction with K3Fe(CN)6 and gas chromatography of the liberated CO. Our improvements included increased baseline stability, shorter analysis time, and simpler standardization. EDTA-containing Vacutainer Tubes (lavender-stoppered) increase the carboxyhemoglobin content of blood stored in them. The carboxyhemoglobin content of blood s...

PURPOSE to evaluate the effectiveness of a vein-viewing device on the success of venipunctures performed by staff nurses on a pediatric surgical unit. METHOD this prospective, non-randomized study examined pediatric inpatients from the age of newborn to 17 years requiring vascular access at a tertiary care center in northeast Florida. The number of attempts, age of the patient, and time requi...

The robotic venipuncture is proved to obtain higher accuracy than manual methods in obtaining venous access for all groups of people including with Difficult Venous Access (DVA). However, the limitations such as improper identification vein, unstable movement arm and unexpected displacement vein resulted failure venipuncture. In this paper, authors proposed an effective model named Intelligent ...

The aim of the study was to describe the construction of a course on peripheral venipuncture using the Information and Communication Technologies. This is a methodological research, developed at the Federal University of Ceara from January to March 2012. The construction phases are: the analysis, design and development according to the theoretical framework of Galvis-Panqueva. In the analysis, ...

Using an automated immunoprecipitin method, we assayed human sera for 10 proteins: haptoglobin, orosomucoid, transferrin, alpha1 antitrypsin, alpha2-macroglobulin, IgG, IGa, IgM, complement C3, and complement C4. Blood from 14 healthy subjects (25-40y) was sampled on six separate days. From each venipuncture serum was divided into four eliquots; two were assayed on the day of venipuncture and t...
