Blood samples obtained from 363 sequentially recruited tuberculosis suspects or treated patients were processed immediately (day 0) and at different times after receipt of the sample [∼24-h (day 1) or ∼32-h (day 2)] with and without adding T-Cell Xtend.

..although the use of T-Cell Xtend appeared to reduce the number of conversions/reversions this reduction was not statistically significant.
