Primary Objective:

1. To evaluate the performance of the new T-SPOT.TB test and the conventional TST for screening of Latent Tuberculosis infections in patients with cancer and those undergoing Hematopoietic Stem Cell Transplant.

Secondary Objectives:

  1. To examine the factors associated with positive response to T-SPOT.TB and the TST (tuberculin skin test) in patients with anergy.
  2. To determine the impact of immunosuppressive and antineoplastic therapy on the screening performance of T-SPOT.TB and the TST in cancer patients.

Primary Outcome Measures:
  • Rate of Positive Results of T-SPOT.TB (%) [ Time Frame: Study period 2 Years ] [ Designated as safety issue: No ]
    Number participants with postitive T-SPOT.TB test results compared to total positive results, derived from Center for Disease Control (CDC) Criteria used for LTBI positive skin test (i.e. a tuberculin skin test (TST) with 5 mm or more of induration). For those individuals with >5 mm induration on TST, chest radiograph performed. Fisher's exact test used to assess the association between categorical variables and the testing results of T-SPOT.TB or TST.

Biospecimen Retention:   Samples With DNA

A blood sample will be collected and used to perform the T-SPOT. TB test.
