ProPhase Labs, Inc. announced that testing volumes exceeded well over 300,000 PCR COVID-19 tests during Fourth Quarter 2021. These record results are significantly greater than the Company's previous record levels of approximately 110,000 tests performed in First Quarter 2021 due to growth in the Company's diversified and expanding customer base for testing services and increased demand for COVID-19 testing related to the emergence of the Omicron variant. The Company has significantly expanded headcount to over 250 laboratory professionals (up from approximately 50 laboratory professionals in the past quarter) to meet the increased demand for PCR COVID-19 testing.

This increase has facilitated the Company's return to testing results within 48 hours on average from the time of receipt.
