Deluxe TB Testing Arm Set (3)

With a soft, lifelike feel, these three models train students to read TB test results by feeling for and measuring skin indurations. One beige model and the brown model feature variations in skin color that typically occur around test sites. A second beige model lacks the appearance of erythema, reinforcing the idea that accurate assessment relies on measurement of the induration, not of any accompanying redness. An essential teaching tool.
