To determine if a correlation exists between Light’s criteria and a dipstick method of measuring the protein content of pleural fluid to diagnose pleura tuberculosis in an HIV prevalent, resource limited setting

It is challenging in resource limited health facilities to diagnose TB Pleural effusion based on the golden standard- “Lights criteria”. This research aims at validating an alternate method to diagnose TB Pleural effusion. Patients presenting with a unilateral pleural effusion, will have a pleurocentesis performed. Pleural fluid total protein and LDH will be measured together with serum levels to calculate Lights criteria. In addition a dipstick measurement of pleural fluid protein content will also be measured. The proposed research aims to identify if a correlation exists between Lights criteria and dipstick measurement.
