About Opiate Screen, Blood in South Pasadena
The opiate screen, blood examines a blood sample for opiates, a class of drugs that includes both naturally occurring compounds and certain semi-synthetic derivatives.
Laboratories typically use immunoassay as the initial screening method. An immunoassay applies antibodies that bind to opiate compounds, producing a signal when the target is present above a defined cutoff. Because screening assays are designed for broad detection rather than precise identification, a reactive result is generally considered presumptive.
When a screen is reactive, the laboratory may confirm the finding with a more specific technique such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry. These methods separate and identify individual compounds, allowing the result to be reported as confirmed rather than presumptive.
Results are reported as negative or reactive, and confirmed results may name the specific opiate detected. Turnaround is typically one to three business days, depending on whether confirmation is required. Preparation follows the lab's instructions, and collection is performed by a trained phlebotomist.
