Because measurements of GFR are tedious, estimated GFRs based on creatinine or cystatin C are widely used for assessing kidney function. Both measured GFRs and the Staging System for CKD based on GFR have analytical and clinical shortcomings. The advantages of serum creatinine and cystatin C, and eGFR will be...

This article explores the potential benefits of point-of-care testing in the ED. Price and St. John provide a detailed description on how to approach four common aspects of point-of-care testing (POCT) in the ED, specifically, the challenges of adopting POCT, the impact of POCT on clinical decisions, the impact of...

Point-of-care testing (POCT) covers a broad range of pathology and non-pathology testing. The volume of POCT is rapidly increasing with an annual growth rate of 12-15 %. By virtue of its compactness, portability, and the feasibility of operation by non-laboratory personnel, where fast and accurate testing methods and...

With the ultimate goal of improving patient care, adoption of point-of-care testing (POCT) continues to grow at a high rate. The ability to deliver fast and reliable results near the patient is a key driver for improving patient outcomes and optimizing clinical workflow. While there are many advantages, controlling...

Point-of-care pathology testing is becoming increasingly common in hospitals, clinics and doctors’ offices; anywhere where time is critical and results are required at the patient’s side.  However, results must be accurate and reproducible to be meaningful, and it is imperative that a close eye is kept on...

Neonates nearly always experience their single largest day of blood loss on the day of birth due to admission laboratory testing. The term "admission laboratory testing" refers to the initial blood tests done when a baby is born and admitted to the NICU.  Total circulating blood volume in a 3.5 kg term newborn is 280...

Emergency Department (ED) overcrowding is becoming an increasingly international issue.  Although the problem is not only resolved by ED change management (but rather requires a system-wide solution recognizing the complex interdependencies of consumer expectations, human resources, information systems immaturity and...

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...

When collecting blood for blood gas analysis, it is important to remove air bubbles from syringes to avoid erroneous results, especially for pO₂, with a number of factors affecting the potential magnitude of the interference to pO₂ by air bubbles.  In this study, we calculate the expected theoretical changes in pO₂...
