Tests that measure Norepinephrine and Total Catecholamines (calculated): Quest Diagnostics 1

Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

Panels that include this biomarker

Catecholamines, Fractionated, Plasma 314
3 analytes · Plasma · Fasting not stated · Turnaround Set up: Mon-Sat (p.m.); Report available: 3-6 days
Method and collection
Method
Liquid Chromatography/Mass Spectrometry (LC/MS)
Preparation
Patients should be relaxed in either a supine or upright position before blood is drawn. States of anxiety and stress can cause fluctuations in the catecholamine levels. Patient should avoid alcohol, coffee, tea, tobacco and strenuous exercise prior to collection. Overnight fasting is preferred.
Collection
Draw specimen in a pre-chilled green-top vacutainer. After drawing specimen, place green-top tube in an ice bath. Centrifuge 20 minutes 1000xg. The plasma must be free of RBCs. Freeze on dry ice to transport.

Verify these ranges and sources

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
