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.
