According to Walgreens.com, TB skin testing is available in Walgreens stores that include Walgreens Healthcare Clinics. As of 2015, PPD/tuberculosis testing costs $28, which can be paid in cash, credit, or debit card.
According to Walgreens.com, PPD/tuberculosis testing necessitates the injection of fluid containing the tuberculin organism under the skin. Patients who are infected with tuberculosis acquire a hard, elevated patch on their skin near the injection site. Patients who take the test are required to return 48 to 72 hours later for an examination of the injection site. The provider assesses the injection site and evaluates whether the patient requires additional TB testing, such as chest X-rays and blood tests.
