  1. VI. Comparisons with CgA NETest CgA • Sensitivity • Specificity • Detection • Reproducibility 63 % (25-78%) 93-97% 85-99% 84% (65-98%) 85-95% 15-85% >90% <65% NETest significantly outperforms CgA

  2. Unlike CgA The NETest is NOT altered by: • PPIs • Food intake • Anti-hypertensive medication • Age

  3. What if your CgA is negative? 55 patients with low-CgA secreting NETs Chromogranin A Levels Elevated 0/55 (0%) NETest 50/55 Abnormal (91%) NETest detects tumors when CgA levels are normal
