<div>Background: Performing all the diagnostic tools before subjecting animals for designed experimental study is time consuming and economically not feasible. Furthermore, it may divert the researchers from original planned work to other areas. But these factors not acceptable to compromise in the assessment of effect of different regenerative agents, drugs and herbal preparation on liver. This is important to prevent any diversions in the actual results of the research due to the prior infection caused by Strobilocercus fasciolaris the lab animals. The study aimed to detect Strobilocercus fasciolaris infected Wistar albino rats using biochemical parameters as a diagnostic marker before subjecting the animals to any designed experimental study.&nbsp; 
 
Methods: The study mainly utilizes abdominal exploration, morphological examination of the larvae, histopathological examination of liver and finally the biochemical parameters changes in the concerned animal. 192 animals used for this study in that 32 had single to multiple cysts in the liver on abdominal exploration. Characteristic Strobilocercus larval morphology, histopathological alterations on liver and serological biomarkers was studied. 
 
Result: Our results showed that the serum levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, glucose, gamma glutamyl transferase, blood urea nitrogen, and total protein can be used as indicators to measure the severity of Strobilocercus fasciolaris larva infection in rats.</div>
