Reference Interval:
By report
Interpretive Data: Refer to report.

Refer to Statement B under Testing Information at http://www.aruplab.com.
Note: A positive result indicates the presence of a PAX-FKHR chromosomal translocation.  A negative result does not entirely exclude the presence of a PAX-FKHR chromosomal translocation.
