Biodesix, Inc. is a diagnostic solutions company. It offers two tests (Nodify Lung tests) that assess the risk of cancer in lung nodules and three tests (IQLung tests) that provide treatment guidance after a lung cancer diagnosis. Nodify CDT and Nodify XL2 tests, marketed as Nodify Lung Nodule Risk Assessment, assess the lung nodule's risk of lung cancer to help identify the appropriate treatment pathway. The Nodify CDT test is a blood-based test that detects the presence of seven autoantibodies associated with the presence of tumors. The Nodify XL2 test is a blood-based proteomic test that evaluates the likelihood that a lung nodule is benign to help identify patients that may benefit from surveillance imaging. GeneStrat ddPCR, GeneStrat NGS and VeriStrat tests, marketed as part of its IQLung testing strategy, are used following diagnosis of lung cancer to detect the presence of mutations in the tumor and the state of the patient’s immune system to help guide treatment decisions.
