Analytical Validity: Help
The deletion assay detects the most common gross deletions reported in at-risk ethnicities. The sensitivity depends on the ethnic background of the individual. Rarer known alpha-globin deletions are not detected by this assay. Further, this assay does not detect: deletions that abolish the regulatory activity of the region leading to … View more
