Leptospirosis--clinical spectrum and correlation with seven simple laboratory tests for early diagnosis in the Third...

Twenty-four patients who were clinically suspected of having leptospirosis were subjected to 7 simple commonly available laboratory tests. The 21 patients who had 3 or more positive tests were confirmed serologically to have leptospirosis. The high frequency of acute abdominal pain (71.4%) as a major presenting symptom and the laboratory findings of raised serum amylase levels in a high percentage of patients (84.2%) were especially noteworthy.
