Nodify XL2 is a blood-based lung nodule test intended for the patients who are ≥40 years old with incidental 8-30 mm lung nodules having ≤50% risk of malignancy. It is also called as BDX-XL2 test. The Nodify XL2 test measures two proteins associated with an inflammatory response to lung cancer to help physicians identify nodules that are likely benign.
