MARK-B COVID-19 Antigen Test

Simple . Accurate . Fast .

The MARK-B™ COVID-19 Ag test is a electrochemical sandwich immunoassay that is used with the MARK-B™ 1 analyzer intended for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in nasopharyngeal swab specimens.




*The MARK-B™ 1 analyzer(MB-100) and the MARK-B™ COVID-19 Ag are CE marked.

Benefits : COVID-19 antigen test

Deliver lab-quality results in 15 mins.

Test results in 15 minutes

Fast diagnosis with results in 15 minutes in various locations such as clinical laboratories, hospitals etc.

Turn-around Time

Sensitivity  94.4%

specificity  100.0%

 The clinical performance of MARK-B™ COVID-19 Ag was established with a study using NPS specimens, which have been previously characterized and were supplied by a biorepository in the United States. In the clinical performance, seventy-two (72) samples were measured, resulting in a sensitivity of 94.4% (34/36) and a specificity of 100.0% (36/36).


Enable the physician to verify infection quickly, begin proper treatment and to initiate isolation precautions helping prevent further spread of infection.
