22685-2Tyrosine/Creatinine [Molar ratio] in UrineActive

Part Descriptions

LP15793-0   Tyrosine
Tyrosine is an aromatic amino acid and its urine levels rise in tyrosinemia, TNT (Transient Neonatal Tyrosinemia), cystinosis, hartnup disease, methionine malabsorption, and alkaptonuria.

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.
