Assessment of Rose Bengal test in diagnosing Egyptian human brucellosis.

A total of 30 patients suffering from brucellosis were suspected based on history taking, clinical manifestations and positive serum tube agglutination test (at titer > or = 1/160). The followings were done for all cases; complete blood picture (differential leucocytic count) and liver function tests, serodiagnosis of Brucella (serum tube agglutination test (STAT) as well as Rose Bengal test (RBT) and PCR. The study aimed to analyze the diagnostic value of RBT as compared to STAT and PCR for human brucellosis, and to evaluate the sensitivity, specificity, accuracy, the cost and the time consuming of RBT as compared to STAT and PCR.
