| description | Measurements of guanidinoacetate (GAA) and creatine (Cr) in serum or plasma are performed for biochemical diagnosis of Guanidinoacetate methyltransferase (GAMT) deficiency, an inherited metabolic disorder of creatine metabolism that is characterized by mental retardation, developmental delay or regression, mental retardation, expressive and cognitive speech delay, and intractable seizures and movement disturbances.[OMIM: 612736] [PMID: 15234334] | ||||||
| status | ACTIVE | ||||||
Fully-Specified Name | |||||||
| component | Creatine & guanidinoacetate panel | ||||||
| property | - | ||||||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||||||
| system | Ser/Plas Ser = Serum Plas = Plasma | ||||||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||||||
