Laboratories Working Together.

GelbChem scientists have teamed up with other leading Newborn Screening (NBS) labs across the United States to standardize a second-tier biomarker test recently implemented in a number of US states.

In December 2019, GelbChem distributed q-NMR certified psychosine dried blood spot (DBS) calibrator sets to the four participating labs. GelbChem quality control analysts will share quantitative LC-MSMS data from these QC DBS with participating labs who are working together to ensure that results are consistent across their states.



By standardizing controls in Newborn Screening LC-MSMS tests, we can ensure that false-positives are minimized and that rare genetic diseases are consistently caught early enough to save lives.
