According to Walgreens.com, Walgreens stores with Walgreens Healthcare Clinics provide tuberculosis skin testing. As of 2015, PPD/tuberculosis testing costs $28 and is payable with cash, credit, or debit card.
Walgreens.com adds that PPD/tuberculosis testing requires the subcutaneous injection of fluid containing the tuberculin bacterium. Patients who are exposed to the TB bacterium acquire a hard, elevated region at the injection site. After 48 to 72 hours, test-takers return for an examination of the injection site. The provider evaluates the injection site and assesses if the patient requires more TB testing, such as chest X-rays and blood tests.
