NEW YORK (360Dx) – Scientists at Seattle Children's Hospital are developing mass spectrometry-based protein tests for screening newborns for various immunodeficiency disorders.

The researchers have formed a company, Key Proteo, to support the effort and are planning a large-scale pilot study to evaluate their assays, said Sihoun Hahn, principal investigator at Seattle Children's Research Institute and leader of the effort.

Hahn has received four grants from the National Institute of Allergy and Infectious Diseases totaling $3.7 million in support of the work.
