*These are estimates based on the turnaround time at the University Hospitals of Leuven.
†Alternatively, a 1×10 µm FFPE section between 25 and 300 mm².
‡If less microdissection is necessary.
FFPE, formalin-fixed paraffin-embedded; RUO, research use only;SNV, single nucleotide variant; VCF, variant call format.
