It was determined that there was a statistically significant relationship between positivity of QTF with TST psitivities and TST enduration diameters.Conclusion: In this study the findings indicated that QTF is very usefull in determining and following LTBI as a confirming test for healthcare workers who have close and longterm contact with tuberculosis patients and whose TST tests were positive.
