The Brazilian Ministry of Health uses a score for the diagnosis of tuberculosis in pediatric patients.
Parameters:
(1) clinical manifestations
(2) thoracic X-ray findings
(3) contact with an adult with tuberculosis
(4) history of BCG vaccination and results of tuberculin test
(5) nutritional status

where:
• Symptoms: fever or cough, loss of energy, sputum production, weight loss, night sweats.
• The table shows a gap for BCG < 2 years ago with tuberculin reaction 10 to 15 mm. In the implementation this will be assigned 5 points.
• The system does not incorporate HIV status.
total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: -15
• maximum score: 60 (assuming that only 1 score is given for each parameter)
• The higher the score the more likely the patient has pulmonary tuberculosis.
Total Score |
Pulmonary Tuberculosis |
<= 25 |
unlikely |
30 to 35 |
possible |
>= 40 |
very likely |
where:
• The smallest increment in the score is 5 points, so the total score is not continuous.
