How does meconium drug testing work?
Meconium drug testing begins with an immunoassay. Positive results are confirmed and quantitated by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Drug confirmation is necessary because some prescribed or over the counter medications cross-react and produce a positive screening result.
