Objective:
To assess the diagnostic value of the T-SPOT.TB test in cases of breast turberculosis (BTB) in China.
Methods:
We enrolled 13 female patients with primary BTB as the BTB test group and 10 healthy volunteers as the control group. The 2 groups underwent T-SPOT.TB tests and tuberculin skin tests (TSTs) before receiving a core-needle biopsy or excision biopsy. We then collected and analyzed T-SPOT.TB and TST data.
Results:
The sensitivity of the T-SPOT.TB test for detection of BTB (84.6%) was significantly greater than that of TST (53.8%) (P <.05); the specificity of each test (80.0% and 60.0%, respectively) for BTB was not significantly different (P >.05).
Conclusion:
The T-SPOT.TB test could be a useful adjunct to current tests for diagnosis of BTB and could be used for early diagnosis of this condition.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
