TB-PCRXpert MTB/RIFT-SPOT结核感染诊断Objective:The paper aims to detect and evaluate the effectiveness of TB-PCR, Xpert MTB/RIF, and T-SPOT in tuberculosis diagnosis. Method:By performing the TB-PCR, Xpert MTB/RIF
Method:By performing the TB-PCR,Xpert MTB/RIF sputum test and T-SPOT blood test among 256 patients with active pulmonary tuberculosis and 182 non-tuberculosis. Result The positive rates are respectively 31.6%(TB-PCR sputum test),75.9%(Xpert MTB/RIF sputum test),and 96.5%(T-SPOT blood test...
"Overall, our study identifies and validates a simple [polymerase chain reaction (PCR)]-based test from accessible blood samples that predicts TB in heterogeneous African populations with intermediate to high TB burdens," write Sara Suliman, PhD, MPH, from the University of Cape Town, South Afric...

Blood samples will be collected if HIV test has not been performed in the last 6 months in children, and if viral load and CD4 count has not been performed in those PLHIV in the previous 3–6 months, and TST/IGRA will be performed at base- line, if available (see Table 1...
CSF can have a high white cell count (from 0-1500/mm3with lymphocytic predominance in majority and polymorphic pleocytosis earlier in the disease course), an elevated protein level, and a low glucose concentration. CSF cultures might be positive in most cases (up to 80%), and PCR (Xpert ...
