Gastroccult Gastric Occult Blood & pH Tests

Gastroccult tests give clinicians a fast, reliable way to detect occult blood and measure pH in gastric aspirate or vomitus — critical information when evaluating upper GI bleeding, monitoring antacid prophylaxis, or screening patients at risk. Unlike fecal occult blood systems, Gastroccult is specifically buffered and stabilized for the acidic gastric environment, so results stay accurate where standard guaiac tests would fail.

This collection carries the Hemocue Gastroccult line. The Gastroccult Chemistry Reagents (66115A) come in a 15 mL liquid dropper bottle for developing both the occult blood and pH portions of the test. Paired with them, the Gastroccult Test Kit (66040A) includes 40 slide cards with product instructions — enough for 40 visual-read tests on gastric aspirate or vomitus samples, supporting occult blood detection, pH assessment, and antacid prophylaxis monitoring.

Buyers often ask how Gastroccult differs from Hemoccult: the answer is the sample source and chemistry. Hemoccult detects blood in stool; Gastroccult is validated for gastric contents and includes a built-in pH indicator, letting you confirm both bleeding and acidity from a single specimen. Results are read visually within seconds, requiring no instrument. To keep testing accurate, match reagent lot handling to the slide instructions and store both components as directed — the developer and the cards are designed to work as a system.

When stocking your lab or nursing station, plan reagent and slide quantities together so you don't run short of developer mid-supply. For related point-of-care diagnostics, browse our broader diagnostics and occult blood tests collections.
