In December 2019, Reditus Laboratories made a significant breakthrough by acquiring a
real-time reverse transcriptase polymerase chain reaction (RT-PCR) machine. This cutting-edge
technology enabled the lab to conduct highly sensitive mRNA detection and quantitation,
proving instrumental in the mass testing of the American population for the Covid-19 virus.
Expanding Capacity
In March 2021, Reditus Labs underwent a substantial expansion, enlarging its laboratory from
