MEDICAL MARKET DEMANDS HIGH ACCURACY AND REPEATABILITY: HOW EXERGEN'S INFRARED TEMPERATURE SENSORS HELP TO ACHIEVE THIS AND MORE

APPLICATION NOTE: POINT-OF-CARE TESTING (POCT)

Point-of-care testing (POCT) is medical diagnostic testing performed at or near a patient’s bedside. As opposed to conventional medical testing, which entails sending specimens to laboratories, POCT yields results in minutes instead of hours or days.

POCT can include blood glucose testing, blood gas, metabolites and electrolytes analysis, etc. Tests are performed on portable instruments, with the use of disposable test strips or cartridges. The challenge with POCT instruments is to provide the complexity of conventional lab equipment in small, portable devices.

APPLICATION NOTE: PLATE READERS

For many plate reader assays performed in (hospital)laboratories it is essential to monitor and control the temperature of liquid samples accurately. In plate readers the results of assays can be affected by temperature fluctuations of the samples, risking faulty diagnosis for patients. Governments are installing strict regulations for laboratories to control the temperature in their laboratory instruments. Contact thermometers are ruled out as they contaminate the samples and influence the temperature of the samples. Exergen noncontact infra-red temperature sensors are the only available option to measure sample temperature accurately.

RELEVANT TECH NOTE #99: IRT/C HEAT BALANCE SERIES FOR MEDICAL APPLICATIONS

The Heat Balance (HB) Series of IRt/c infrared thermocouples have the ability to measure the internal temperature of the target material, non-invasively, by employing a patented heat balance technique. A typical application in medical equipment is monitoring or controlling the temperature of fluid transported through disposable tubing when warming or cooling:
