The novel coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2
(SARS-CoV-2), was announced as a pandemic in March 2020. Different diagnostic laboratory tests have been used to detect
the infection. Each diagnostic tool, such as Chest Computed tomography (CT) imaging, genome sequencing, nucleic acid
amplification methods, whole genome sequencing, microarray, and serology testing have several advantages and
disadvantages. Nucleic acid amplification methods are better diagnostic tools for the detection of SARS-CoV-2 in early
stages of the infection, while serological tests are more appropriate for the recognition of previously infected patients. In this
review, we will briefly consider each diagnostic method, and discuss its pros and cons.
