title: Precipitation test--a rapid method for diagnosis of tuberculous meningitis.
abstract: Precipitation test (modified Lavinson's test) was conducted in 125 cases of meningitis. Of these, 50 cases (proved cases of tuberculous meningitis) who served as positive controls showed positive response for the precipitation test in 96% and in 25 cases of negative control group (cases of meningitis other than TBM), it showed only 4% positivity. The remaining 50 cases of TBM where the cytological and biochemical findings were not in correlation with clinical diagnosis of TBM, showed 92% positivity for early diagnosis of TBM.
