Cannabidiol, Serum

Clinical Use

Use

Measures cannabidiol (CBD) concentration in serum. Interpretation includes mean peak CBD plasma concentrations post-dose and emphasizes that the blood-to-serum or plasma concentration ratio is unknown; guidance helps in pharmacokinetics and patient monitoring contexts.

Special Instructions

Not provided.

Limitations

Reporting limit is determined per analysis. Limited comparability due to unknown blood-to-serum/plasma ratio; oleamide interference may affect identity or quantity of result. FDA has not cleared or approved this test—it was developed as an analyte-specific reagent by NMS Labs.
