Questions & Answers

Q: What is the purpose of an immunoassay screening in drug testing?

An immunoassay screening is used to detect potential drug classes present in a blood sample, providing presumptive positive results that require confirmatory testing for specifics.

Q: Can metabolites of drug substances have psychoactive effects like the parent drug?

Yes, certain active metabolites can have effects on the body similar to the parent drug, while others may be inactive and serve as indicators of drug ingestion.

Q: How does the half-life of a drug or metabolite impact its presence in the body?

The half-life indicates the time taken for half of the drug or metabolite to be metabolized, influencing the duration of presence in the body before complete elimination.

Q: Why is confirmatory testing necessary after a positive immunoassay drug screen?

Confirmatory testing is crucial to definitively identify specific drugs present in a sample, as immunoassay screens can produce false positives requiring further verification.
