The process of patient sample testing, whether performed in the clinical laboratory or at the point of care, is the sum of three distinct phases. The first is the preanalytical phase, which includes test selection as well as sample collection and handling.  The second is the analytical or measuring phase that...

The following is a copy of an article from Nursing 2007, Fall 2007 Volume 37 Number 8 - Supplement: ED Insider, Pages 14 - 16 The D-dimer level is a measure of clot formation and lysis that results from the degradation of cross-linked fibrin. Widely used as an indicator for the presence of disseminated intravascular ...

Clinical laboratory measurement of serum/plasma creatinine concentration has been used to assess patient kidney function for well over 50 years.  With the incorporation of creatinine analyses to blood gas and other point-of-care platforms the test is now available outside the laboratory, at the bedside and in the...

The following is a copy of an article from Evidence-Based Practice, 2007; 10(12):1-2. Venous thromboembolism refers to a spectrum of disease that includes both pulmonary embolus and deep-venous thrombosis (DVT). More than 250,000 people in the United States are diagnosed annually with venous thromboembolic disease;...

PURPOSE – The purpose of this article is to discuss lean as a learning system in a hospital ward. DESIGN/METHODOLOGY/APPROACH – Discusses lean as a learning system in a hospital ward. FINDINGS – The Toyota veterans are fond of saying, lean is about “making people before making parts” or, in the wards’ context,...

The growing role of cardiac markers has been elucidated in patients with acute coronary syndrome, heart failure and other cardiovascular diseases. The markers can be cytosolic like heart-type fatty-acid-binding protein (H-FABP) and creatine kinase MB (CKMB), myofibrillary like troponin T (TnT) and cardio-endocrine...

Clinical laboratory measurement of serum/plasma creatinine concentration has been used to assess patient kidney function for well over 50 years. With incorporation of creatinine analyses to blood gas and other point-of-care platforms the test is now available outside the laboratory, at the bedside and in the clinic.  ...

PURPOSE – The purpose of this paper is to show how over the last 18 months Bolton Hospitals NHS Trust have been exploring whether or not lean methodologies, often known as the Toyota Production System, can indeed be applied to healthcare. DESIGN/METHODOLOGY/APPROACH – This paper is a viewpoint. FINDINGS – One’s...

Clinical laboratory test results are a very important parameter in diagnosis, monitoring and screening. 70-80 % of decisions in diagnosis are based on laboratory results and more and more laboratory analyses are requested. Thus a lot of data are provided and it is therefore imperative for patient care (and safety)...

One of the principal utilities of arterial blood gas (ABG) analysis is to help assess blood oxygenation status. The two ABG parameters used for this assessment are pO₂(a) (partial pressure of oxygen in arterial blood) and sO₂(a) (% of total hemoglobin that is saturated with oxygen). In health pO₂(a) is maintained...
