Recommendation of a simple identification method for LPL. If there is no splenomegaly in the 1st or 2nd generation then passage should proceed to the 3rd generation (a). If there is splenomegaly in the 2nd generation, passage should be stopped, and the line should be terminated (b). If there is splenomegaly in the 1st generation but not in the 2nd generation, then passage to the 3rd generation should proceed, but immediate histopathological examination should be carried out to for a definite diagnosis (c).
