French to English Medical Medical (general)

This term appears in a table of molecular testing results for T-cell receptor gene rearrangement. The patient is suspected of having cutaneous lymphoma. There are three results columns: Sang; Antériorité Peau (these two words are written on separate lines); and Antériorité. The results are reported for gamma TCR genes and beta TCR genes. The results are reported as "Clonal" or "Clonal à xxx bp". The word of interest does not appear anywhere else in the report. Any help would be appreciated. TIA.
