Estimation of galactose-1-phosphate in blood spotted on filter paper. 1976

H N Kirkman, and D C Lanier, and E H Clemons, and J L Sanderford

A method is described for the enzymic estimation of galactose-1-phosphate (Gal-1-P) in blood which has been applied to filter paper and allowed to dry. The successful clinical management of patients with galactosemia depends upon exclusion of galactose from their diet. Earlier studies demonstrated that red cell Gal-1-P is a sensitive indicator of exposure of such patients to galactose. These earlier methods, however, required venipuncture, preparation of washed, packed red cells, and shipment of the sample in dry ice to a central laboratory. With the present method, capillary blood can be drawn by a nonphysician, applied to filter paper and mailed in a conventional envelope at ambient temperature. From this sample, the Gal-1-P content of the red cells can be determined, if the hematocrit is known. These conveniences should allow estimates of Gal-1-P at a frequency more appropirate for optimal dietary control.

D005374	Filtration	A process of separating particulate matter from a fluid, such as air or a liquid, by passing the fluid carrier through a medium that will not pass the particulates. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)	Filtrations
D005693	Galactosemias	A group of inherited enzyme deficiencies which feature elevations of GALACTOSE in the blood. This condition may be associated with deficiencies of GALACTOKINASE; UDPGLUCOSE-HEXOSE-1-PHOSPHATE URIDYLYLTRANSFERASE; or UDPGLUCOSE 4-EPIMERASE. The classic form is caused by UDPglucose-Hexose-1-Phosphate Uridylyltransferase deficiency, and presents in infancy with FAILURE TO THRIVE; VOMITING; and INTRACRANIAL HYPERTENSION. Affected individuals also may develop MENTAL RETARDATION; JAUNDICE; hepatosplenomegaly; ovarian failure (PRIMARY OVARIAN INSUFFICIENCY); and cataracts.

D005694	UTP-Hexose-1-Phosphate Uridylyltransferase	An enzyme that catalyzes the synthesis of UDPgalactose from UTP and galactose-1-phosphate. It is present in low levels in fetal and infant liver, but increases with age, thereby enabling galactosemic infants who survive to develop the capacity to metabolize galactose. EC 2.7.7.10.

D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
