Are Your Samples Getting Overheated in the Sun?

As summer quickly approaches, the hot weather will soon be coming. When it comes to the summer heat, laboratory lock boxes that are waiting for courier pickup can get overheated because of hot temperatures, which then causes pre-analytical errors. For patients that need immediate test results so that their health care provider can have a better understanding of how to treat them, this can be devastating and can put them in a life-or-death situation. Unfortunately, this is a very common problem that occurs throughout the United States. Here at McShane Welding and Metal Products we are proud to help the clinical laboratory industry keep their specimens cool with our insulated laboratory lock boxes and frozen specimen containers.

Studies show that test results are unreliable after being in laboratory lockers for hours in the heat.

An article in Clinical Laboratory News discusses two studies that were done on the internal temperatures of outdoor laboratory lock boxes and their impact on sample quality. DNA sample will break down as it sits at room temperature because enzymes that are normally present are gone. Therefore, it is recommended that samples get transferred to a laboratory as quickly as possible. On the other hand, when a sample is placed into cooler temperatures, the breakdown of DNA slows down and there is a decline in the rate of enzymatic reactions. Laboratory lock boxes were used in the study to be able to determine the temperatures inside the laboratory lock box. In one of the studies, the findings showed that outside temperatures caused the inside of the laboratory lock box to reach 116.4 degrees Fahrenheit without ice packs in it. These changes were seen within the time frame of one hour. The laboratory lock box contained samples testing for AST, glucose, lactate dehydrogenase, and potassium. Quality of a sample is determined based off the health care provider’s knowledge of the temperature of their patients’ samples and if they are willing to invest in outside insulated laboratory lock boxes. Most laboratories utilize high quality laboratory lock boxes and monitor the temperatures of the lock boxes every so often. At this time, there are no regulations that tell laboratories as to what environmental controls their samples should be at while during transit or during courier pickups.

Our courier company strongly encourages the use of LabLockers. We have been a customer for over 10 years and no other metal box vendor we tried in the past compares to the quality and customer service we get at McShane. Any business in the courier industry, specifically medical samples, should consider LabLockers.
