Early diagnosis and treatment of diseases are crucial research areas of human health. For early diagnosis, one method that has proven efficient is the detection of biomarkers which can provide real‐time and accurate biological information. Most biomarker detection is currently carried out at localised dedicated laboratories using large and automated analysers, increasing waiting time and costs. Smaller, faster, and cheaper devices could potentially replace these time‐consuming laboratory analyses and make analytical results available as point‐of‐care diagnostics. Innovative biosensor‐based strategies could allow biomarkers to be tested reliably in a decentralised setting. Early diagnosis of COVID‐19 patients has a key role in order to use quarantine and treatment strategies in a timely manner. Raised levels of several biomarkers in COVID‐19 patients are associated with respiratory infections or dysfunction of various organs. Through clinical studies of COVID‐19 patient biomarkers such as ferritin, Interleukins, albumin and …are found to reveals significant differences in their excretion ranges from healthy patients and patients with SARS‐CoV‐2, in addition to the development of biomarkers based biosensor such as stated biomarkers can be used and to investigate more specific biomarkers further proteomic analysis can be performed. This review presents several biomarker alterations in COVID‐19 patients such as salivary, circulatory, coagulation, cardiovascular, renal, liver, C‐reactive protein (CRP), immunological and inflammatory biomarkers. Also, biomarker sensors based on electrochemical, optical, and lateral flow characteristics which have potential applications for SARS‐COV‐2 in the recent COVID‐19 pandemic, will be discussed.
