TB Tests – All volunteers must receive a TB test, or provide documentation that they have been previously tested for TB. You will need to take a T-Spot or QuantiFeron TB test (blood draw) if you do not have proof of a previous TB test within the past six months. Hard copies of your TB test results must be submitted before your first volunteer shift. You may also take a TB skin test; however, xxx requires that you receive two rounds of skin tests in order to volunteer at xxxx. Please make sure that your TB tests are covered by your health care insurance plan as these can be expensive.
