Covid 19 was spread through Corona Virus, this virus was initially infected respiratory tract then to lungs. In the beginning Covid 19 was suspected to spread only with community transformation, later it was assumed that it is a airborn, waterborn and community transformation disease. Recent clinical research reveals that Corona Virus causing Mutations and Point Mutations, still cause is unknown. Covid 19 is unstable in the living body, Once Corona virus is found positive to a person involving in multiple complications in the body such as Cardiovascular Dysfunction, Renal Dysfuction and other complications in the body. Different Hospital shown that when a person was infected with Covid 19 that person was severe for breathing problem and collapsing with unkown cause. The affected person life span was only 48 to 72 hours. The researcher scientists, clinicians are day night trying to take any suitable solution to control and cure Covid 19. Covid 19 patients are found changes in their routine life. There is change in their metabolic functions. There is change in their physics and also in their Biochemical and Molecular parameters. Mostly their Protein synthesis and coagulation profiles are involved in Covid 19. Present study is aimed To investigate the value of D- Dimer, Ferritin, Lactate Dehydrogenase, Prothrombin Time, Activate Partial Prothrombin Time are the significant indicators of suspected COVID19-Patients.
