Adjacent to the Clinical laboratory, supports the processing, analysis, and storage of biological samples collected at the Clinical Laboratory. Analysis performed at this laboratory include CO, nicotine, and cotinine measurements, and verification of drug use abstinence. Over 3,000 samples were processed at this state-of-the-art laboratory in FY22. After initial validation, samples stored at the HPRC Experimental Laboratory can be distributed to diverse other experimental laboratories for studies such as DNA damage and mutation analysis, RNA sequencing, gene and protein expression, and inflammation studies.
