Point-of-care testing has changed how clinicians access laboratory information. Instead of sending every specimen to a central laboratory, a compact analyzer can provide important results during the patient encounter. Two well-known systems in this space are the Abbott i-STAT and the Piccolo Xpress. But which is better? The answer depends heavily on the type of testing your facility needs. The i-STAT is built around a broad range of blood gas, electrolyte, chemistry, coagulation, cardiac and other specialized cartridges, while the Piccolo Xpress is primarily a compact clinical chemistry analyzer using self-contained reagent discs. For emergency departments, critical care, ambulances and acute-care environments, i-STAT has some important advantages. For clinics, primary care facilities and settings needing a broader chemistry panel from a small blood sample, Piccolo Xpress can be extremely attractive. Let's compare them from a practical laboratory and POCT perspective. i-STAT vs. P...
Point-of-care testing (POCT) is revolutionizing healthcare by providing rapid diagnostic results at the bedside, in clinics, and even in remote locations. However, the speed and convenience of POCT come with a critical challenge ensuring accuracy and reliability. Without rigorous quality control (QC), POCT devices can produce erroneous results, leading to misdiagnosis, inappropriate treatment, and compromised patient safety. The Importance of Quality Control in Point-of-Care Testing Unlike traditional laboratory testing, which operates under strict regulatory oversight, POCT is often performed by non laboratory personnel. This increases the risk of errors due to improper technique, lack of calibration, or device malfunctions. Implementing a robust quality control program ensures that results remain accurate, reproducible, and compliant with regulatory standards such as ISO 15189:2022 and CLSI guidelines. Key Elements of Point-of-Care Quality Control To maintain high standards in PO...
