Provided is a method for determining the replicative history of a lymphocyte, preferably a B cell, the method comprising detecting a signal joint nucleotide sequence on an extrachromosomal circular excision product in the lymphocyte, wherein the excision product is deleted from a chromosome to give a chromosomal-coding joint nucleotide sequence, wherein the coding joint is retained in the chromosome, and detecting the coding joint nucleotide sequence in the lymphocyte. Also provided are primers, probes and a control cell for use in a method of the invention. A method provided herein is among others advantageously used to assess recovery of the precursor B-cell compartment, for example, in a patient following bone marrow transplantation
