JHU Comparative Study

WSLH Comparison Study An independent comparison study was conducted by the WSLH Proficiency Testing Program. HemaPrompt FG and Gastroccult (20 slides of each product) were used to compare sensitivity to Hemoglobin in synthetic gastric juice (manufactured by WSLH Proficiency Testing ) over a range of Hgb concentrations (500ug/ml minimum) and pH range 1 - 7. No significant differences were found between the two products and each was found equally suitable for the detection of Hemoglobin in gastric juice in the pH range of 1 to 7. ( September 2003)
