Adrenaline (Epinephrine)



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


This Chromsystems assay allows the standard routine analysis of adrenaline, noradrenaline and dopamine in plasma 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.

For the HPLC analysis of catecholamines in urine, there is an additional method available (order no. 6000).

Sample drawing

  • Blood samples should be drawn from the recumbent patient.
  • 20 µl stabilisation solutuion (900 mg EGTA, 700 mg glutathione in 0,5 M NaOH ad 8 ml, pH 7-7.5 with H2O ad 10 ml) is required per ml blood.
  • Mix, centrifuge.
Sample Preparation
  • Add 500 µl Extraction Buffer to a sample clean up cartridge, shake briefly.
  • Apply 1 to 1.5 ml plasma and 50 µl Internal Standard.
  • Mix for 10 min by inverting.
  • Remove the bottom plug and remove supernatant by vacuum or centrifugation, discard effluent.
  • 3 times: apply 1 ml Wash Buffer, shake briefly, centrifuge (1 min at 2000 rpm, after the last wash step 2 min at 4000 rpm), discard effluent.
  • Mount the plastic tube to the outlet of the cartridge, add 120 µl Elution Buffer, shake briefly, incubate for 5 min. Vortex 30 s.
  • Centrifuge for 1 min at 2000 rpm into the attached plastic tube. Collect eluat and mix well.
  • Inject 20-50 µl into the HPLC system.
