Clonidine Suppression Test (Four-hour) 123158
12 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,” “three-hour,” and “four-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.

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.
