ARDL's Mass Spectrometer Center Ramps Up
For more than three decades, scientists in the Advanced Research and Diagnostic Laboratory (ARDL) at the University of Minnesota have conducted large-scale analysis of biological specimens for NIH-sponsored multi-center clinical trials. The recent expansion of its Mass Spectrometer Center will enable ARDL to bring “gold standard” analysis more fully into its clinical testing operations and help investigators study renal, diabetes, nutritional, cardiovascular and other diagnostic biomarkers.
“Mass spectrometry is increasingly being integrated into clinical laboratories,” said center director Jesse Seegmiller. According to Seegmiller, most large clinical laboratories are now incorporating mass spectrometry systems in their testing repertoire.” Mass spectrometry can help “bridge a gap that has existed for clinical trials and various research studies by obtaining results from a mass spectrometry platform to perform analyses not possible using standard clinical analyzer systems.” One of the most impressive benefits of these systems is the analytical specificity advantages they provide. This has resulted in the mass spec utility in biomarker standardization efforts.
The capability to perform mass spectrometry testing makes ARDL a more versatile laboratory and offers testing options for trials and studies that can be performed in one laboratory, as opposed to multiple labs sharing samples. “This helps studies streamline their sample workflows, potentially increasing efficiency in the study and reducing errors associated with sample handling,” Seegmiller said.
The success of ARDL resides in the quality of the laboratory testing results. The Mass Spectrometer Center will enable principal investigators and staff to develop improved reference measurement procedures expeditiously. “Our goal is to accommodate various projects in epidemiology, clinical medicine, and public health,” Seegmiller said. “We collaborate with other investigators to devise testing options to aid in answering specific scientific questions that ultimately furthers knowledge in disease states, is translated into clinical guidelines, and impacts patient care,” he added.
ARDL faculty are enthusiastic about the center and excited that the department has invested in it, he said.
