GASTRIN

The Gastrin test measures the concentration of the gastrin hormone in the blood, a key regulator of gastric acid secretion and digestive function. Performed via professional at‑home venous sample collection, Touch Connect provides fast analysis through UAE‑accredited laboratories to support timely clinical decisions. This test is important for evaluating abnormal acid production, investigating causes of peptic ulcer disease or refractory GERD, and for detecting conditions such as Zollinger–Ellison syndrome.

• Serum Gastrin
• Fasting Gastrin Level
• Basal Gastrin Concentration

• Recurrent or treatment‑resistant peptic ulcer disease
• Persistent GERD symptoms despite acid suppression therapy
• Suspected Zollinger–Ellison syndrome or gastrinoma
• Unexplained acid hypersecretion or severe secretory diarrhoea
• Assessment of atrophic gastritis or pernicious anaemia with abnormal gastric function

• Professional at‑home venous sample collection by certified phlebotomists
• Rapid processing and reporting by UAE‑accredited laboratories
• Early detection of acid‑secreting disorders to guide treatment
• Reduces clinic visits and accelerates clinical decision‑making
• Clear lab report suitable for review by your treating physician

• At‑home venous blood sample collection by a trained phlebotomist
• Fasting for 8–12 hours prior to the test
