Revolutionising your testing with exsig™ COVID-19 Direct


Welcome back to our latest blog.

All departments have been working tirelessly to find an innovative solution following the bottle-neck of scarce raw materials that clinicians require to test.  SARS-CoV-2 is a continuing pandemic and the demand for the hard to source raw materials continues to be a challenge for many laboratories.
