The diagnosis of leptospirosis is based upon clinical suspicion and lab findings, so lab tests should be considered in a patient with a history of contact with potentially infected animals, soil or surface waters contaminated by animal urine. Leptospires can be found in blood and CSF for the first 7 to 10 days and then in the urine. Hence, in the early diagnosis, specimen of choice should be blood or CSF for culture. From the second week onwards serological tests are useful in the diagnosis.
