Norepinephrine is a hormone released by the adrenal glands in response to stress. It is a neurotransmitter that helps regulate the body’s response to stress. Norepinephrine can be acquired from a patient’s plasma by a clinical test. The most common method for obtaining norepinephrine from a patient’s plasma is by high-performance liquid chromatography (HPLC). This method involves separating the components of the plasma sample by passing it through a column filled with a stationary phase. The norepinephrine is then collected and measured. Other methods for obtaining norepinephrine from a patient’s plasma include enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA). ELISA involves using antibodies to detect and measure the norepinephrine in the sample. RIA involves using radioactive isotopes to measure the norepinephrine in the sample.
