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 084152
3 analytes · Plasma · Fasting not stated · Turnaround 4 - 6 days
Labcorp catalog pageMethod and collection
- Method
- Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
- Preparation
- Patient should discontinue drugs and other substances that may affect measured catecholamine results for at least one week before obtaining the specimen (see Limitations for details).
- Collection
- Draw blood in chilled lavender-top (EDTA) tube. Invert to mix with preservatives. Centrifuge and transfer the plasma to a labeled plastic transport tube. Place on-ice immediately (do not refrigerate) and freeze separated plasma within four hours of collection. Important : The patient should be in a fully recumbent position (lying down) for at least 20 minutes before and during sample collection. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
- Reference notes
- Analyte Adults, ≥18 years (Supine) Dopaminea | 0.0–36.7 pg/mL Epinephrineb | 0.0–55.4 pg/mL Norepinephrinea | 115–524 pg/mL
Clonidine Suppression Test (Three-hour) 123133
9 analytes · Plasma · Fasting not stated · Turnaround 2 - 4 days
Labcorp catalog pageMethod and collection
- Method
- High-pressure liquid chromatography (HPLC) with electrochemical (EC) detection
- Preparation
- The patient should abstain from smoking. Walnuts, bananas, and interfering medications should be avoided for a week prior to specimen collection. An indwelling heparinized catheter is recommended, as venipuncture can cause an increase in the substances for which testing is being performed. The patient should remain recumbent during the entire collection procedure. Thirty minutes after the insertion of the indwelling catheter, blood is drawn for the baseline catecholamine determination. Clonidine hydrochloride (0.3 mg) is given orally, and repeat specimens for plasma catecholamines are collected two and three hours later.1
- Collection
- Draw blood in chilled lavender-top (EDTA) tube. Invert tube to allow preservatives to mix thoroughly. Centrifuge at 4°C (chill carriers if a refrigerated centrifuge is unavailable). Transfer plasma to labeled plastic transport tubes. Freeze immediately at -20°C and ship frozen. “Baseline,” “two-hour,” and “three-hour” should be prelabeled on the transport tubes. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Quest Diagnostics 4 tests
Single-analyte tests
Epinephrine, Plasma 37560
Plasma · Fasting required · Turnaround Set up: Mon-Fri (p.m.); Report available: 5 days
Quest Diagnostics catalog pageMethod and collection
- Method
- Liquid Chromatography/Mass Spectrometry (LC/MS)
- Preparation
- Overnight fasting is required. 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. Patients should avoid alcohol, coffee, tea, tobacco and strenuous exercise prior to collection.
- Collection
- Draw specimen in a pre-chilled green-top tube. Plasma should be separated in a refrigerated centrifuge within 30 minutes of collection and then frozen immediately at -20° C in plastic vials. Each specimen will be invoiced separately.

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.
