NCIt definition : The sodium salt form of an organic phosphate compound that provides phosphate for
nutritional purposes. In addition, sodium glycerophosphate can be used as a phosphate
diluting agent upon internal contamination with the beta-emiting radioisotope phosphate
P 32 (P-32) that competes with P-32 for absorption. As sodium glycerophosphate is
administered in high amounts, the absorption of P-32 is prevented or minimalized.;
