The level of glucose phosphate isomerase (GPI) which is observed more rarely in the population was measured in the patient who had values which supported chronic hemolysis.
Glucose phosphate isomerase is an enzyme which reversibly catalyses transformation of glucose 6 phosphate and fructose 6 phosphate to each other which is the second step of anaerobic glycolysis in the Embden Meyerhof pathway.

The components are (1) tumor markers: HCG-lntact Hormone by IRMA, HCG-Total Hormone (intact, nicked intact, free [beta], nicked, and free [beta], fragments) by chemiluminescence, HCG-Urine test by chemiluminescence, PHI enzyme (phosphohexose isomerase or glucose phosphate isomerase) by enzyme kinetics, and CEA (carcinoembryonic antigen) by chemiluminescence; and (2) peripherally related assays: GGTP, TSH, and DHEA-S.
PHI: Phosphohexose isomerase, EC 22.214.171.124, is also known as glucose phosphate isomerase or phosphoglucose isomerase, and was originally isolated from a human melanoma cell line.
dehydrogenase deficient red cells: resistance to infection by malaria parasites.
Neither significant deficiencies nor an excess of heterozygotes was found in three of four loci in the 6-month-old oysters; the exception was glucose phosphate isomerase (GPI), which showed an excess of heterozygotes (Table I).
Starch gel electrophoresis was used (18, 19) to score the loci leucine aminopeptidase (LAP, EC 126.96.36.199), glucose phosphate isomerase (GPI, EC 188.8.131.52), carbonic anhydrase (AC, EC 184.108.40.206), and phospho-glucomutase (PGM, EC 220.127.116.11).
An anion is any negatively charged ion, including chloride ion, phosphate ion, glucose phosphate
