Diagnostic testing for patients with clinical signs and symptoms suspicious of a disaccharidase deficiency.
Specimen should not be placed on gauze or filter paper, nor should any saline, support or embedding material be added.
Freeze immediately after collection and ship frozen.
This test will not distinguish between primary and secondary causes of disaccharidase deficiencies.
Lactase: > or =14.0 nmol/min/mg protein
Sucrase: > or =19.0 nmol/min/mg protein
Maltase: > or =70.0 nmol/min/mg protein
Palatinase: > or =6.0 nmol/min/mg protein
Glucoamylase: > or =8.0 nmol/min/mg protein
Quantitative values of lactase, sucrase, maltase, palatinase, and glucoamylase are reported. Clinical interpretation of results is provided.
