Palpable TB Testing Arm Set
Made of soft, palpable material for greater realism, students can use these models to practice feeling for and measuring skin indurations to determine whether a patient is infected with Mycobacterium tuberculosis. Beige and brown models feature variations in skin color typically occurring around test sites. Each model depicts indurations of 5 mm, 10 mm, 15 mm, and no reaction. Accompanying instruction card explains that readings should be based on measurements of induration, not erythema. Each model is 3" x 6½" x 1".
