suggestions, each product must have an insert that provides specific details when performing the actual test. When samples are collected, they must be stored at room temperature 18–25°C (64–77°F) during shipping and storage conditions for at least one week, or results could be inaccurate. Temperature labels—which change color if temperatures fall out of range—can assure that everything is stored at the proper conditions.
Getting the
temperature right A liquid crystal thermometer, temperature strip, or plastic strip thermometer contains heat-sensitive liquid crystals that change color to indicate different temperatures. Liquid crystals possess the mechanical properties of a liquid, but have the optical properties of a single crystal. Tey can distinguish temperatures within 0.1°C. Liquid crystal temperature labels use
color change to indicate temperatures or temperature ranges. Because these are printed on labels, they can be provided in almost any size and shape to fit any need, along with real-time temperatures. Te thin, flexible temperature indicators feature adhesive or magnetic backing that are easily atached where traditional thermometers cannot. A good label clearly communicates the optimal temperature, whether for health, safety, efficient use, quality, or convenience. When accuracy and reliability mater, top companies in drug testing, medical device, pharmaceutical, and industrial sectors rely on liquid crystal thermometers. For saliva testing, a dual card can be
used with both ascending and descending temperature monitoring. If the label turns red, it indicates that, before use, the test product was stored at temperatures that were too high or too low, potentially affecting the accuracy of the test. In the same way, it can also indicate if saliva was not stored at room temperature aſter use.

Temperature is a good telltale Te accuracy of drug testing relies on how closely the administrator follows Department of Transportation (DOT) and/or HHS procedures. When poor procedures or testing methods are used, the information obtained may be misleading and inaccurate. One of the most accurate means of assuring a viable sample has been collected is temperature. It is a very empirical indicator whether or not something is a miss. ❚
