The present invention determines lymphocyte clonality by contacting a sample comprising nucleic acid molecules (1) of lymphocytes with forward and reverse primers (10, 20) and amplifying the nucleic acid molecules (1) by performing PCR pre-amplification to form barcoded PCR products (50). The barcoded PCR products (50) are amplified using adapter-specific forward and reverse primers (30, 40) in a PCR application into amplified barcoded PCR products (60), which are sequenced. The sequence reads are demultiplexed, mapped to respective TCR or BCR clonotypes and used to determine lymphocyte clonality for the sample. The forward and/or reverse primers (10, 20) are barcoded by comprising UMIs (14, 24) protected inside hairpin loops.
