Patients with poor hypoglycemia awareness, had an increase in copeptin levels from 3.3 (±1.6) to 3.6 (±1.4) pmol/L (p = 0.4), whereas patients with good hypoglycemia awareness had an increase from 3.0 (±1.8) to 4.2 (±2.4) pmol/L (p = 0.03) (Figure 2a, 2b). The gene discussed is AVP; the disease is Hypoglycemia.
