Gastrin Stimulation (10'), serum           PROTEIC DIET: 180 gr of beef without fats Samples: Basal, 30, 60 min.    Response: Increasing at least 2 times basal value. CALCIUM GLUCONATE PERFUSION: 15 mg Ca/Kg during 3 hours Samples: Basal y 3 hours. Response: Increasing less than double GLYCOCOLA : 240 mL 2 % orally Samples: Basal, 30, 60 min. Secretina Test:        The Secretina test consists of the determination of 4342-GASTRINE, SERUM every 5 minutes during a period of half an hour, after the administration of 2 units of secretin per kg of weight intravenously. In patients without a gastrinoma, a decrease in the baseline gastrin levels occurs after the stimulus or they do not change. On the other hand, in patients with a tumor, there is an increase of more than 200 pg / ml over the baseline gastrin levels, a rise of 2 times over the baseline is also positive. SODIUM BICARBONATE: 240 mL 2% orally. Samples : Basal, 30, 60 min. Response: Double increasing basal value. BASAL SAMPLE: 13 - 115 pg/mL                  Method:Chemiluminescence Delivery term: 1 day
