Part Descriptions

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.

LP431281-7   6(R+S)-oxo-propylpiperidine-2-carboxylate
6-oxo-pipecolate (6-oxo-PIP) and two diastereomers of 2-oxopropylpiperidine-2-carobylic acid (2-OPP) are identified biomarkers for pyridoxine-dependent epilepsy (PDE-ALDH7A1). PMID: 30663059 PMID: 34138754 PDE-ALDH7A1 is characterized by seizures that are responsive clinically and electrographically to daily supplements of pyridoxine (vitamin B6) and not well controlled with anti-seizure medications. Two forms, classic and atypical, of PDE-ALDH7A1 have been described.[NCBI Books: NBK1486] Source: LOINC
