We offer sampling services for human tissues and biofluids. For instance, saliva samples are collected to test a novel in vitro diagnostic assay. Moreover, tissue samples are collected to test for mutations in the EGFR, PD-L1, and RAS genes. Liquid biopsy is performed to assay a novel non-invasive molecular diagnostic test. Blood samples were collected for a validation study of a tuberculosis diagnostic test. We are professionals in the logistics of human tissues and biofluids and follow professional and ethical norms.
