What is Catecholamines Plasma?

The catecholamines plasma test is a serological (blood) test conducted to calculate the catecholamines level in the blood. The term catecholamines are used for a wide array of naturally occurring hormones like dopamine, norepinephrine, and epinephrine. It is conducted to diagnose adrenal gland tumors. This test can also be conducted for children to diagnose neuroblastoma, cancer which is common in children.

In this test, a simple blood sample is taken, and the sample is sent for diagnosis. It is advised not to eat 6-12 hours before the test. High levels of catecholamines in the blood indicate tumors on the adrenaline gland, and the doctor will accordingly plan the future course of treatment.
