Optimizing Point-of-Care PT/INR Testing
Marcia L. Zucker, PhD, Clinical Laboratory News, September, 2014

Coagulation testing, especially the global coagulation test prothrombin time (PT), is not exactly an ideal laboratory test. I say this because PT does not evaluate a well-defined analyte with results reflected as a concentration of that analyte. Rather, PT assesses the interaction of more than a dozen different enzymes within a blood sample, and a PT test result reflects a clotting time measured at a different end point for each instrument used.

In addition, the reagent for the PT test, thromboplastin, is not standardized. The original thromboplastin reagents were crude preparations from multiple tissue types from several different species. Today, thromboplastins may consist of recombinant rabbit or human brain protein complexed with phospholipids. There is limited standardization, achieved through use of the international normalized ratio (INR), for patients on long-term oral anticoagulant therapy with vitamin K antagonists such as warfarin and coumarin.

Quality Practices & POCT
Defining quality in POCT is offering more than just quick results
By Charles K. Cooper, MD, September 4, 2014, Advance for Administrators of the Lab, Issue 9

Point-Of-Care Testing
The world of laboratory medicine has changed considerably in the last decade. Specifically, the need for hospitals to improve capacity utilization and efficiency as more patients seek care has propelled clinical laboratories into a bold new journey in point-of-care testing (POCT). As new efforts bring advanced testing to point-of-care (POC) locations, there must also be new criteria for evaluating POC tests. To effectively meet the goal of POCT-which is to offer high-quality testing at primary care locations to streamline patient management-POC diagnostics need to meet quality standards across a broader range of categories. Beyond providing accurate and fast results, the quality of these tests must be equally determined by evaluating their scalability, ease-of-use, cost ­structure, and effectiveness in improving healthcare system efficiency.

Managing Risk: Preventing Errors at the POC
July 2014, by Sarah Njoroge, PhD and James H. Nichols, PhD, DABCC, FACB, Clinical Laboratory News

Although point-of-care testing (POCT) provides rapid test results and the opportunity for faster medical decisions, the unique risk of errors with POCT raises concern over the quality and reliability of test results. In contrast to the central laboratory, where errors predominately occur in the pre- and post-analytic phases, POCT errors occur primarily in the analytic phase of testing. This might be related to the non-laboratory staff involved in POCT, but might also be due to test limitations and misuse of POCT in extreme environmental conditions.

Clinical personnel with minimal laboratory skills and experience, such as nurses and patient care technicians, perform the majority of POCT. These operators are focused on patient care and do not necessarily understand why they must handle POCT—a task viewed as a laboratory role and not a job for clinical staff.

Yet regulatory standards hold the laboratory director responsible for managing and supervising POCT quality. In a clinic setting, the laboratory director may be a physician, but in a hospital or health system, the chief of pathology and head of the central laboratory often become responsible. POCT is thus at odds with both the clinical staff performing the test as well as the laboratory staff responsible for supervising the test. This conflict creates a situation ripe for errors. More >
