"The use of 4 - galactosil - xylose for the assessment of the presence of xylose in the urine, usable for the evaluation in vivo of intestinal lactase as a diagnostic review of the deficiency of this enzyme.The invention relates to the use in humans of a method which is based on the use of 4 - galactosil - xylose and involves an alternative technique to evaluate xylose in the urine.The method consists in measuring the concentration of xylose in the blood after oral administration of 4 - galactosil - xylose to the patient, and the use of the said method more appropriate in the case of newborns.The invention also refers to the technology used for the in vivo assessment of intestinal lactase activity, by means of a noninvasive examination stop diagnosis of a deficiency of this enzyme.That is to assess directly the overall activity of enzyme in individual and not to determine the consequ00b3u00eancias of Se deficiency.The method of the invention does not require specialized equipment, does not cause any obvious discomfort for patients with a lactase deficiency, and is extremely reliable.Thus eliminating the inconvenience of diagnostic tests currently used.
