Is LC MS more reliable test for Newborn screening or is it GC MS?

LCMS (actually) LCMS/MS goes the half way for newborn screening. Its then the GCMS which comes for rescue. It clarifies the results given by LCMS and says with accuracy whether it is a positive or a negative case, against what was indicated in the LCMS screening. GCMS is mostly based on urine sample while LCMS needs blood spots. Thats where GCMS already scores a big point above LCMS. Further, GCMS "confirms" a disorder, while LCMS stops at "maybe". GCMS tests for a massive range of disorders while LCMS is limited to a few class of disorders. GCMS is the future of screening, while LCMS is the present of screening.
