        Subjects must meet all the following criteria to be enrolled in the trial

          1. Able to understand and willing to sign the ICF

          2. Healthy male and female subjects, 18-55 years of age, non-smokers, or subjects must
             have been non-smoking for at least 3 months prior to their screening visit.

          3. Has adequate venous access

             signs results may be repeated once if abnormal result is observed at the initial
             reading. Moreover, abnormalities found in the ECG may need to be confirmed by repeated
             measurements.
