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: ...

Chris Price and Andrew St John have followed their book Point-of-Care Testing for Managers and Policymakers with another look at the subject from strategic vision to change management and implementation in Point-of-Care Testing: Making Innovation Work for Patient-Centered Care. In their latest book the authors give...

Despite the pervasive measurement of cardiac troponin (cTn) for the diagnosis of myocardial infarction (AMI) and acute coronary syndromes (ACS), the continuous evolution of assays and guidelines for their application has created uncertainty among laboratorians and clinicians: criteria for the choice of assay and...

The appropriate number of significant figures is important in order to have a meaningful level of resolving power when reporting analytical concentrations. Various methods or criteria can be used when estimating how many significant figures are needed. In most cases three significant figures (two true plus one...

Troponin values above the 99th percentile and increasing/falling values found by serial testing in addition to signs and symptoms of myocardial ischemia means AMI. Low troponin values, near or below the 99th percentile, can be used for prognosis. Highest hazard ratios were found when using the 90th percentile,...

Recent studies of D-dimer as a “rule-out” test for deep venous thrombosis (DVT) frequently have used duplex ultrasound rather than venography as the gold standard. Because duplex ultrasound has limited ability to image the calf veins, there is potential for ultrasound studies to classify patients with calf DVT as...

In an exclusive acutecaretesting.org interview, Dr Mario Plebani, Head of the Department of Laboratory Medicine at the University Hospital of Padova, Italy and international patient safety advocate, talks about how laboratory, clinicians and manufacturers can work together to reduce errors in testing and diagnosing...

Modern analytical devices for testing biological fluids, such as blood, have now developed a sophistication that ensures the quality of the analytical result is capable of matching that achieved in the central laboratory.    Complementary developments are focused on reducing operator-related and connectivity-related...

What does it take to create and maintain a quality point-of-care program in a world-renowned healthcare institution? acutecaretesting.org recently asked that question to Paula Santrach, MD, Interim Chair of the Dept. of Laboratory Medicine and Pathology at the Mayo Clinic in the US. She came back with a list* of 10...
