Does a negative parr result rule out lymphoma?

In brief: No?

Polymerase chain reaction (pcr) for antigen receptor rearrangements (parr) is not a test i would necessarily consider in initial lymphoma diagnosis.
Lymphoma is diagnosed (ideally) by an excisional (not just needle) biopsy and/or bone marrow biopsy. There are many additional tests including molecular (eg, pcr) tests that can be used to further subclassify diagnosis.

In brief: Perhaps you know

What parr means, but I do not.
No image can discern benign or malignany. Only a biopsy showing architecture, or cell studies proving clonality and gene rearrangements can indicate the diagnosis. But a parr is a mystery to me.
