Tuberculin Test in Children with Malnutrition

Abstract

Tuberculin tests with Heaf's multiple-puncture method, as well as intradermal tests with varying strengths of old tuberculin, were carried out on 402 children with severe malnutrition. From the radiological and bacteriological findings 51 children (12.5%) were considered to have active tuberculosis. The Heaf test was positive in only 11 of these children, but the intradermal test using 100 tuberculin units was positive in a further 18. This confirms previous findings that tuberculin sensitivity is impaired in malnourished children, and suggests that a higher dose of tuberculin is more likely to elicit a positive response.
