This testing will be performed using a laboratory developed test (LDT) which utilizes liquid chromatography with tandem mass spectrometry detection (LC-MS/MS) to replace the current method which uses liquid chromatography with electrochemical detection (LC-ECD). This new LC-MS/MS assay will provide enhanced specificity and is considered the gold standard analytical technique for this testing.
There are several important changes associated with this change to LC-MS/MS testing.
