Catecholamines in Urine - HPLC

Clinical relevance

The catecholamines adrenaline (epinephrine), noradrenaline (norepinephrine) and dopamine are biogenic amines, which play a central role in the body as hormones and neurotransmitters. Adrenaline and noradrenaline are produced in the adrenal medulla and the sympathetic nervous system. Dopamine is a neurotransmitter in the brain and acts as a local messenger substance in the peripheral nervous system.

The determination of catecholamines has clinical significance in the diagnosis of pheochromocytomas and other tumours affecting the nervous system. These diseases result in the production of surplus catecholamines, which are then excreted in the urine. 24-hour urine collection is the preferred method for tumour screening. The plasma concentration is determined to localise the tumour or to perform pharmacological function tests. Furthermore, the concentrations of adrenaline and noradrenaline are important indicators for cardiac insufficiency, cardiac diseases and arteriosclerosis.

Product advantages

• Simple and safe handling
• Low detection limits
• Low analysis costs
• Ready-to-use components

Our kit allows the standard routine analysis of adrenaline, noradrenaline and dopamine in urine with an isocratic HPLC system and electrochemical detector. A very specific sample preparation using solid phase extraction guarantees simple and safe handling of the samples as well as reproducible results.

The kits 2020/COMBI and 6000/COMBI are available as alternative methods that allow the combined determination of catecholamines and metanephrine with one column.

For the HPLC analysis of catecholamines in plasma, there is another method (# 5000) available.
