A photo in the article “Tuberculosis testing: Which patients, which test?” (J Fam Pract. 2015;64:553-557,563-565) incorrectly depicted how the induration that arises from a tuberculin skin test should be measured. According to the Centers for Disease Control and Prevention (http://www.cdc.gov/tb/publications/factsheets/testing/skintesting.htm), the induration should be measured across the forearm, perpendicular to the long axis (elbow to wrist), as indicated by the yellow arrows below.
