Similarly, in patients with AVP deficiency, the median OT at baseline was 73.9 pg/ml [65.3–81.6] and slightly increased after glucagon injection to 114.9 pg/ml [70.9–140.9], resulting in a median increase of 36.8 pg/ml [–2.2–51.2]. This evidence concerns the gene GCG and neurohypophyseal diabetes insipidus.
