CTK Biotech Gains CE Mark for Onsite COVID-19 Self-Test

Poway, Calif.-based CTK Biotech has received a CE mark certification for its Onsite COVID-19 antigen self-test.

The single-use test, which can detect SARS-CoV-2 antigens in nasal swab specimens from infected individuals, is intended for use with self-collected samples within the first seven days after symptoms begin.

CTK Biotech said it will begin shipping the test this month to countries that accept the CE mark.
