Note

To complete Maternal T Cell Engraftment in SCID testing, samples should be collected to perform the following three tests: (1) A buccal  brush collected from the patient for Maternal T Cell Engraftment in SCID, Pre-Engraftment Specimen (ARUP test code 2014694), used as a genetic baseline for the patient. (2) A peripheral blood sample from the biological mother for Maternal T Cell Engraftment in SCID, Maternal Specimen (ARUP test code 2014704), used as a genetic baseline for the mother. (3) A peripheral blood sample collected from the patient for Maternal T Cell Engraftment in SCID (ARUP test code 2014699). T cells isolated from the blood sample will be genotyped for comparison to the patient and biological mother baseline genotypes. If T-cell sorting is not completed on the blood sample before submission of Maternal T Cell Engraftment in SCID (ARUP test code 2014699), BMT Cell Isolation (ARUP test code 2005498) will be added to each order of Maternal T Cell Engraftment in SCID (ARUP test code 2014699). Additional charges apply for cell isolation.
