Thin-layer chromatographic screening tests for carbohydrate anomalies in plasma, urine and faeces

Thin-layer Chromatographic screening methods for anomalies of carbohydrate metabolism are described. For detection of anomalies with an increased plasma concentration of fructose and galactose in plasma or serum is one-dimensionally chromatographed on precoated plates without deproteinization. For detection of an abnormal urinary or faecal excretion urine (without desalting) or faecal extracts are two-dimensionally chromatographed together with an internal carbohydrate standard. Both methods are relatively simple and yield reproducible results with high sensitivity.
