12-Hour Prednisolone Study
Test Code
PKCPX
Description
This assay is used to monitor prednisolone concentrations in serum 12 hours after administration, ensuring therapeutic effectiveness while minimizing toxicity.
Collect
Collect Serum in an 8-10 mL plain red top tube. Any other type of tube may influence accurate drug level quantification.
Patient Prep
Separate serum from cells immediately by centrifugation and aliquot into a polypropylene or similar plastic tube. Use a separate tube for each test ordered. Allow room for expansion of sample inside tube.Preferred Volume: 2.0 mL of serum
Minimum Volume: 1.0 mL of serum
