Pathological changes of biochemical, hematological and coagulation analyses in patients with COVID-19 disease

The identification of patients with poor prognosis and early detection of COVID-19 disease complications are made possible by pathological analyses of routine hematological, coagulation, and biochemical tests. Interpreting analyses needs to be done within the framework of each patient’s unique clinical picture. It’s also critical to keep an eye on changes at the individual parameter level. From May 20th, 2021, to March 30th, 2024, a comprehensive search of literature was carried out using international databases, such as PubMed, Embase, Web of Science, Scopus, and the Cochrane Library, in compliance with the PRISMA guidelines. The research question was formulated using the PICO strategy. The following terms were used: biochemical parameters in COVID-19, hematological parameters in COVID-19, blood coagulation parameters in COVID-19, indicators of inflammation, and indicators of tissue damage in SARS-CoV-2. Routine hematological, coagulation, and biochemical tests are primarily used to monitor the progression of the disease and the effectiveness of treatment rather than being utilized for the established diagnosis of COVID-19 due to their low specificity. Molecular genetics and immunological techniques should be used to determine the COVID-19 disease diagnosis.
