One hundred Forty (140) patients each one had 2 venous studies for Acute Deep Venous Thrombosis, non-invasive (new test) and invasive (gold standard).  No evidence of disease was detected in 54 patients. In 12 cases the non-invasive studies were negative, but the invasive tests were positive. 68 patients showed Acute DVT by both tests. In 6 cases the non-invasive studies were positive, but the invasive studies were negative. The number of True Negative is _________
