Refer to Statement B under Testing Information at http://www.aruplab.com.
Note: A positive result indicates the presence of monoclonal T-cell population within the sample.  A negative result does not entirely exclude the presence of a T-cell receptor gene rearrangement (or monoclonal T-cell population) in the sample.
