This technique can predict SCID even when lymphocyte counts are within the normal range. Newborn screening of X-SCID based on TREC count in dried blood samples has recently been introduced in several states in the United States including California, Colorado, Connecticut, Delaware, Florida, Massachusetts, Michigan, Minnesota, Mississippi, New York, Texas, and Wisconsin. In addition, pilot trials are being performed in several other states beginning in 2013.
