Linearity in Laboratory Testing
Linearity is the ability to provide laboratory test results that are directly proportional to the concentration of the measurand (quantity to be measured) in a test sample.

Read MoreImplementing a laboratory quality management system can seem a daunting project. Learn how you can deliver consistent, high-quality, and cost-effective laboratory services by participating CLSI’s updated Laboratory Quality Management System (LQMS) Certificate Program.
Read MoreContinuous glucose monitoring (CGM) systems are medical devices that measure glucose in the interstitial fluid just under the skin and use algorithms to predict blood glucose values from the measurement. The use of self-monitoring of blood glucose (SMBG) devices or glucose meters has led to more normal glucose levels and lower risk of cardiovascular and long-term complications in both type 1 and type 2 diabetes.
Read MoreMost laboratories use methods such as QC, equipment calibration measurement, QA measurements of process performance, and more recently, implementation of a qualitymanagement system, to determine the quality of examination results and laboratory services. However, laboratory personnel often believe that staying within budget is sufficient, not considering that every time work is redone, the cost of laboratory services, as well as the cost of quality (COQ), increases.
Read MoreWorld Antimicrobial Awareness Week (WAAW) is celebrated November 18-24. This is a week to raise awareness about global antimicrobial resistance (AMR) and to encourage best practices among health care workers, the public, and policy makers to avoid the further emergence and spread of drug-resistant infections. The slogan for 2020 is "Antimicrobials: handle with care.” The theme for the human health sector for WAAW 2020 is “United to preserve antimicrobials.”
Read MoreImplementing a quality management system (QMS) can help a laboratory run more efficiently by reducing costs and nonconformances. Most importantly, in the US, a QMS is a requirement under CLIA regulations for passing and maintaining accreditation.
Read MoreEach year on October 14 we celebrate World Standards Day, which is a day to pay tribute to the collaborative efforts of thousands of experts worldwide who develop the voluntary technical agreements that are published as international standards.
Read MoreSeptember is Newborn Screening Awareness Month. 2020’s theme is “Expect newborn screening.” Newborn screening is a state public health service that reaches each of the nearly 4 million babies born in the United States each year. It ensures that all babies are screened for certain serious conditions at birth and for those babies with those conditions, it allows doctors to start treatment before some of the harmful effects happen.
Read MoreWorld Patient Safety Day is celebrated on September 17. This year WHO will launch a global campaign emphasizing health worker safety as a prerequisite for patient safety and urging people to show their commitment to make health care safer for everyone. Health Worker Safety: A Priority for Patient Safety has been selected as the theme for this year. The 2020 theme will be promoted through the slogan “Safe health workers, Safe patients.”
