Stool D-Galactose Control - QC Applications

Certified 0.5% D-galactose standard confirms reducing sugar detection sensitivity across Clinitest tablet and copper reduction workflows.

Clinical laboratories verify galactose recovery preventing false negative lactase deficiency diagnosis. Quantitative recovery confirms assay linearity.

Quality control certificates 0.5±0.05% concentration, sterility, and 12-month refrigerated stability. Stool matrix-matched prevents method mismatch.
