A liquid biopsy, also known as fluid biopsy or fluid phase biopsy, is the sampling and analysis of non-solid biological tissue, primarily blood. [ 1 ] [ 2 ] Like traditional biopsy , this type of technique is mainly used as a diagnostic and monitoring tool for diseases such as cancer , with the added benefit of being largely non-invasive.
In medicine, a nerve biopsy is an invasive procedure in which a piece of nerve is removed from an organism and examined under a microscope. A nerve biopsy can lead to the discovery of various necrotizing vasculitis , amyloidosis , sarcoidosis , leprosy , metabolic neuropathies, inflammation of the nerve, loss of axon tissue, and demyelination .
