As the pandemic has struck the predicted second wave, public struggles persist with lifestyle restrictions, but our knowledge to identify and fight the virus has significantly progressed. At present testing generally consists of Polymerase Chain Reaction (PCR ) or Lateral Flow Tests (LFT) also known as rapid or antigen tests.

From the outset of the COVID-19 outbreak, testing for SARS-CoV-2 has been a priority. Initially just having a test for COVID-19 was a scientific success, enabled by the publication of the first viral genomic sequence in January 2020. Here we highlight some of the key testing events that have taken place, and their outcomes.

In quantitative PCR (qPCR) and reverse transcriptase quantitative PCR (RT-qPCR), the cycle threshold (Ct) value is the number of nucleic acid amplification cycles required for the signal generated by the amplification of a specific target DNA to cross a set threshold.

This article covers swab type and selection, transport products and medium enabling a smooth transfer of patient samples to the laboratory for analysis. Additionally, we discuss the implications of cycle thresholds and whether they should be assessed in patient prognosis.

Two types of tests for SARS-CoV-2 currently predominate. The first are molecular tests, based on PCR technology, that detect the presence of viral nucleic acid and therefore indicate a current infection. The second are serology tests.
