Health Services offers two methods of tuberculosis screening.
- Tb Skin Test (PPD). This test is done by the administration of a small amount of purified protein derivative just under the skin of your forearm. You must return to have the test read by a healthcare provider within 48 – 72 hours of administration. These tests are administered every weekday except Thursdays. There is a $16 fee for this test.
- T-spot. This test requires that a sample of blood be drawn from a vein in your arm. The blood sample is then sent to an off-site laboratory, Oxford Diagnostics. The test results usually are available within 48 hours. There is a $56 fee for the T-spot.
