Examples of case analysis. (A,B) Positive results for the rearrangement of the VH(FR3)/JH region in the IGH gene of BALF lymphocytes. A peak higher than that of the positive control is detected on a low background (monoclonal pattern; A) or several distinct peaks are seen on a polyclonal background (oligoclonal pattern; B). (C) A peak for the positive control. (D,E) Results of MALT1 translocation analysis by FISH. In case of MALT1 translocations, the orange and green signals are separated (D), whereas in a normal cell they are fused (E).
