The ELISpot assay is a sensitive technique applied to assess cytokine-producing memory/effector T cells and human leukocyte antigens (HLA)-specific IgG-producing B cells. Besides the fact that the method is laborious and is difficult to standardise between laboratories, it may provide valuable information on the immune response of recipients before and after organ transplantation.
In this article, we briefly review the recent literature and discuss the clinical significance of the ELISpot assay in predicting the risk and incidence of allograft rejection and survival.
