Calcium is an essential mineral required for numerous biological functions. In circulation, calcium is found in three different fractions, anion-bound, protein-bound and free or ”ionized”. The amount of calcium in each of these fractions is dependent on the concentration of hydrogen ions, anions and plasma proteins....

BACKGROUND: Hospitals in countries with public health systems have recently adopted organizational changes to improve efficiency and resource allocation, and reducing inappropriate hospitalizations has been established as an important goal, as well as avoiding or buffering overcrowding in Emergency Departments. AIMS: ...

In the ED, 25 % of patients with angina pectoris with suspected AMI are wrongly diagnosed (no cardiac involvement). As a result, the patient risks are increased and resources are wasted. We investigated the effect of point-of-care testing (POCT) on ED processes, resource needs, patient risks and overall costs. POCT...

Emergency departments (ED) are challenged by increasing patient visits, overcrowding and prolonged length of stay (LOS). The cause of these problems is multifactorial. Delays in the laboratory are often perceived as contributing to delays in care and increased LOS. Implementation of selected point-of-care tests in...

Abdominal aortic aneurysms (AAAs) are currently identified by incidental imaging or ultrasound screening. The potential diagnostic and prognostic value of D-dimer for AAA was assessed in this study. 1260 men from a population-based ultrasound screening study were included, of which 299 had small AAAs monitored by...

Postoperative cardiovascular event including myocardial infarction or heart failure is a major cause of morbidity after non-cardiac surgery. Preoperative evaluation including estimation of the probability of perioperative cardiac event and application of non-invasive testing or beta-blocker has been developed, but...

Hemodialysis and related treatments for those with failing kidneys all involve blood flow through a circuit outside the body. This extracorporeal circuit - the dialysis machine and its connections from and back to the body - is a non-physiological, pro-coagulant environment.  To counter the tendency for patients'...

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...

As healthcare seeks to provide better care with fewer resources, Point-of-Care Testing steps in to move key diagnostic or screening tests to the patient’s bedside. The results can have a significant impact on a patient outcome and operational costs.

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...
