The signs & symptoms resemble a wide range of bacterial & viral diseases & sometimes can present as food poisoning, chemical poisoning & snake bite also due to which the diagnosis is often missed. This review article aims to focus on the role of Dark Field Microscopy (DFM), culture, Enzyme Linked Immuno Sorbent Assay (ELISA), Macroscopic Slide Agglutination test (MSAT), Microscopic Agglutination Test (MAT) and Faine’s criteria in the diagnosis of leptospirosis.
