Standardization of Veterinary Susceptibility Testing

Not all laboratories use CLSI or other available standards for interpretation of veterinary culture specimens. However, if a laboratory does not adhere to a public standard, such as CLSI’s, breakpoints may vary and interpretation may be inconsistent from laboratory to laboratory, or among different regions of the country.

Detection and Culture of Fungi in Clinical Specimens

There has been an enormous increase in the frequency and severity of fungal infections in recent years. Culture from a clinical sample is the gold standard for diagnosis of fungal infection as it has the advantage of yielding the specific etiological agent if positive. Moreover, culture allows for susceptibility testing.There has been an enormous increase in the frequency and severity of fungal infections in recent years.

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.

Optimal Continuous Glucose Monitoring System Performance and Data Accuracy

Continuous 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.

Do You Know the Cost of Quality in Your Lab?

Most 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.
