Test Code MTRBM MatePair, Targeted Rearrangements, Hematologic

Useful For

Second-tier testing in hematologic specimens when previous cytogenetic or FISH testing have detected an acquired chromosome abnormality of unknown significance

 

Determining the size, precise breakpoints, gene content, and any unappreciated complexity of abnormalities detected by other methods such as conventional chromosome and FISH studies

 

Providing important diagnostic, prognostic, and therapeutic information critical to proper patient management
