According to Walgreens.com, the company offers TB skin testing in its locations with Walgreens Healthcare Clinics. As of 2015, PPD/tuberculosis testing costs $28 and can be paid with cash, a credit card, or a debit card.
According to Walgreens.com, PPD/tuberculosis testing necessitates the injection of fluid containing the tuberculin organism under the skin. The skin at the injection site becomes hard and elevated in patients who have been exposed to the TB bacterium.
After 48 to 72 hours, test participants return for an examination of the injection site. The healthcare professional assesses the injection site and decides whether the patient needs more TB testing, such as blood work and chest X-rays.
