In one case (10%), positivity with 1 of those 2 primer sets was the only molecular evidence of biclonality; 2 clonal populations were identified with IGH FR1 and IGH FR3 primer sets in 4 cases (40%; 2 [20%] with IGH FR1 and 2 [20%] with IGH FR3), and 2 of these cases (the ones with biclonal results for IGH FR1) also demonstrated biclonal populations with the IGH FR2 primer set.
