COVID-19 caused by SARS-CoV-2 is considered an emerging disease that results in severe acute respiratory syndrome. Coronaviruses, as single-stranded RNA viruses, have envelope and positive-sense genome. Virion’s nucleocapsid contains genomic RNA and phosphorylated nucleocapsid protein, which is located within the phospholipid layers and is covered with spike proteins. Although considerable research improvements have occurred, the virus origin is yet obscure. There are several factors that contribute to the development of COVID-19, such as mutations, viral loads, and the survival of the virus in the laboratory, or related factors such as age, sex, and immune status. Proper diagnosis of changes in biochemical and immunological factors affecting COVID-19 leads to the rapid detection of this disease. Finding suitable biochemical and immunological biomarkers could help us in early diagnosis and reducing the casualties of this disease. However, further studies for finding a good solution to early diagnosis require a better understanding of the mechanism of action of this virus. In this review, we review the biochemical and immunological biomarkers used for laboratory diagnosis of SARS-CoV-2 (COVID -19).
