Protein electrophoresis in tuberculosis.

Serum electrophoresis was done in 31 patients with pulmonary tuberculosis and 62 age and sex matched controls. Protein values amongst controls were higher than those described by others. In tuberculosis there was significant decrease in total proteins, and albumin with corresponding increase in globulin, mainly due to an increase in gamma globulin fraction. There was no significant increase in alpha-2 levels. Decrease in albumin/alpha-2 ratio was significant in sputum positive cases, but it was due to reduction in albumin rather than increase in alpha-2 globulin. Decrease in albumin/alpha-2 ratio in this study was not diagnostic of tubercular activity.
