Our Laboratories


State-Of-The-Art Laboratories

Designed to achieve optimal efficiency, Quest’s main laboratory is equipped with state-of-the-art equipment, supported by Siemens Labcell® and Aptio® system to manage high-volume specimen processing.

From the moment a test tube is placed onto the automated specimen track, the Siemens Sample Manager and Aptio® Input-Output Module precisely recognise which analyser to direct the specimen and automatically route it to subsequent analysers for optimal efficiency. This reduces the number of steps required to sort, process, and archive specimens.

Quest has also invested in a Sysmex Haematology Sample Tracking (HST) line that manages thousands of blood specimens daily with minimal human intervention. The automated HST line reduces the occurrence of human error, improves safety and processing speed, while increasing the accuracy of test results.

Always committed to maintaining a robust and advance information technology systems with optimal redundant capacity, maximum system uptime and scalability are achieved so as to best fulfill customers’ needs.
