两个不同的肺结核测试
“The T-SPOT.TB test is a unique, single-visit blood test for tuberculosis (TB) screening, also known as an interferon gamma release assay (IGRA). ”
“The QuantiFERON®-TB Gold In-Tube (QFT-G) is a blood test for use as an aid in diagnosing Mycobacterium tuberculosis infection (both latent tuberculosis infection and active tuberculosis disease).“
"Both are equally acceptable for screening latent TB in Health Care workers.

T-Spot is very labor intense and you can only perform limited testsper day (it requires culturing patient's T-lymphocytes overnight in the presence of TB-specific antigens).

QFT-Gold-in-tube test can be automated and you can test 6-8 plates (microtiter plater=s) per day and resuylts can be inter-phased for reporting.  We average 2500-3,000 tests per month.  T-spot test may be better for immuno-comprised patients since they have much lexx T-cell.   please feel free to contact me if you have further questions.  yenb@ccf.org

东方老师已经讲得很清楚了。
