SARS-CoV-2 RT-PCR testing

SARS-CoV-2 (previously 2019-nCoV) is a member of the coronavirus family and the causative agent of coronavirus disease 2019 (COVID-19). Since the first cases of a severe respiratory disease were reported from Wuhan, China, in December 2019, infections have spread rapidly around the world.


Considering the rapid escalation, spread and persistence of COVID-19 worldwide, testing remains essential and is required all over the world.

Current altona SARS-CoV-2 test kits reactivity analysis

Reactivity of molecular diagnostic tests is determined by the sequences of the oligonucleotides contained in the reaction mix. RNA viruses in particular have an inherently high mutation rate leading to changes in the genome sequence during every replication event. SARS-CoV-2 is no exception. We at altona Diagnostics are well aware of the importance to constantly monitor the emerging and circulating sequences and we update the reactivity analysis of our assays on a regular basis. Mutations in the viral genome occur in every gene and untranslated region and are not limited to the S gene. Our S gene assay is located in a conserved region coding for the membrane fusion subunit (domain 2) of the spike protein. Until now, we have not found any mutations that would cause our S gene assay to fail.

altona Diagnostics SARS-CoV-2 RT-PCR kits detect Omicron sequence variant

By now the Omicron viruses account for over 98% of the publicly available sequences since February 2022 and constitute the genetic background from which new SARS-CoV-2 variants will likely emerge. Recent reactivity analysis by altona Diagnostics confirmed that the S gene assays contained in the SARS-CoV-2 associated products of the RealStar®, AltoStar® and FlexStar® product lines detect all described genetic variants including all previously discovered Omicron variants.
