Abstract
The hemagglutination on the tuberculoss patients published by Middlebrook and Dubos in 1948 has been appraised by various investigators.
It has been confirmed that the results of the test almost parallels with the clinical symptoms of tuberculosis and we were impressed that it is a highly specific test when applied in the active stage of tuberculosis.
However, there are still many aspects yet to be clarified by further studies, namely with regard to the kind of old-tuberculin solution, the pH of physiological saline solution, and the influence of tuberculin injection etc.
In spite of these unsolved questions, the results I have obtained in this test showed a remarkable accuracy viewed along the lines of the clinical symptoms.
By this test it is possible to examine the existence of antibody directly in the streaming blood. This point distinguishes itself from the other serological tests, and some new developments may be expected to come out of this test.
