Biochemical role of serum ferratin and d-dimer parameters in COVID 19 diagnosis

One and one only most unforgettable pandemic is coronavirus 2019 (COVID 19) which is the most memorable pandemic of the twenty-first century. The diagnosis of COVID19 is based on purely clinical symptoms and real time reverse transcription polymerase chain reaction (RT-PCR) test. The role of COVID19 during this pandemic was horrible in diagnosing the disease with RT-PCR as this disease was documented to be a symptomatic disease. Serum ferratin and D-dimer tests plays a major role in identifying the infections in the human body specifically, patients diagnosed with COVID19. Serum ferritin levels are important for an immune response mediator that rises in severe COVID-19 instances, and elevated ferritin levels may trigger a cytokine storm by exerting direct immunosuppressive and pro-inflammatory effects. d-dimer is used to identify the clots in the blood. COVID-19 patients were found to be clotting of blood and d-dimer is recommended. The blood of the COVID-19 patients were found to clotted than the patients were prescribed the anticoagulant Injections are prescribed. d-dimer can be used as a biomarker in the COVID-19 patients by measuring the d-dimer levels and analyse the mortality and severity. Pulmonary complication risk can also be identified. d-dimer is a mandatory and an essential test in the COVID-19. Numerous COVID-19 vaccines have been shown to have great efficacy levels through clinical trials. COVID-19 vaccines are not 100% effective, although the condition is mild or moderate and can be controlled if COVID-19 is affected. In this review, I have only included serum ferritin and d-dimer; however, C-reactive protein, vitamin D levels, and prolactin were also attributed to COVID-19. This review concludes the importance of RT-PCR, serum ferratin, and d-dimer testing in identifying COVID-19 infection in humans.
