Clinical Pearls
Mok says that a physician has the option to conduct a plasma test when the diagnosis is being made. By the time the lung cancer diagnosis is confirmed, a physician will have plasma testing results available. If the test is positive, treatment can begin, but if it is negative, a physician can subject the tumor for testing. If good tissue cannot be obtained for testing, a physician can use plasma as a testing method. However, Mok says, physicians should be aware that plasma test sensitivity is only 76%.
