Clonidine, Serum or Plasma
Also known as: CLONIDI SP
Use
The Clonidine, Serum or Plasma test is used for therapeutic drug monitoring. It assists in determining the appropriate dose for patients using clonidine to manage hypertension, attention deficit hyperactivity disorder (ADHD), or other medical conditions. The measurement of clonidine levels helps clinicians assess treatment efficacy, ensure patient safety, and avoid potential toxicity, which is crucial given the variations in individual metabolism and drug clearance rates.
Special Instructions
This test is not performed at ARUP Laboratories; therefore, separate specimens must be submitted if multiple tests are ordered. Ensure that the specimen is separated from cells as soon as possible, or within 2 hours of collection, and transferred to an ARUP standard transport tube.
Limitations
The Clonidine, Serum or Plasma test does not determine clonidine levels in patients taking transdermal clonidine or in situations where the drug is administered in forms not specified within the test parameters. Additionally, external factors such as improper storage conditions or delay in specimen processing may affect the results. Variability in individual response and metabolism also necessitates careful interpretation within the clinical context.
