Frequently Asked Questions (FAQ)

How is D-xylose standard used in clinical diagnostics?

D-xylose is widely used in the D-xylose absorption test, a diagnostic tool for evaluating intestinal function and malabsorption syndromes. By administering a known dose of D-xylose and measuring its excretion in urine or concentration in blood, clinicians can assess the ability of the small intestine to absorb monosaccharides. A high-purity D-xylose standard ensures accurate calibration of test methods and reliable patient results.

Why choose a certified reference material instead of regular D-xylose?

A certified reference material (CRM) provides guaranteed purity, traceability, and batch-to-batch consistency, which are critical for reproducible results in regulated environments such as pharmaceuticals, clinical laboratories, and food testing. Regular chemical-grade D-xylose may contain impurities or lack documentation, which can compromise analytical reliability.

What analytical techniques are compatible with D-xylose standards?

D-xylose can be analyzed using HPLC, GC, LC-MS, and spectrophotometric methods. It is particularly important in carbohydrate profiling, metabolic flux analysis, and bioenergy research. Using a standard ensures accurate quantification and method validation.

How should D-xylose standards be stored for maximum stability?

D-xylose standards should be stored at room temperature in a dry environment, protected from humidity and light. Improper storage may lead to degradation or moisture absorption, which can affect purity and analytical performance. Sealed containers with desiccants are recommended for long-term stability.
