Immunoprofile studies in patients with pulmonary tuberculosis. III. Study of haemolytic complement in serum and phagocytic activity of blood neutrophils.

The total level of haemolytic complement in serum, and the phagocytic activity of blood neutrophils were found to be significantly increased in patients with active pulmonary tuberculosis prior to treatment. A relationship could not, however, be demonstrated between the elevation in the two studied values and the extent of tuberculous changes in the lungs of the patients.
