A) VoC-Identification after screening PCR: positive samples need to be searched for in the freezer for secondary PCR or sequencing. Sample mixing possible. RNA may already be degraded due to more freeze-thaw cycles. Follow-up PCRs need time and sequester urgently needed PCR capacities.
B) GenXPro VoXcreen PCR identify VoCs during screening PCR to save time, resources and to free PCR capacities.
