The Tygerberg score is a clinical decision tool that allows the clinician to decide whether pericarditis is due to tuberculosis or not. It uses five variables: Weight loss (1 point) Night sweats (1 point) Fever (2 points) Serum globulin >40 g/L (3 points) Blood leukocyte count <10 billion/L (3 points)
A total score of 6 or more is highly suggestive that tuberculosis is the cause of the pericarditis.
