Glycine AF Level Quantitative is an advanced test that uses gas chromatography–mass spectrometry (GC-MS) to determine glycine levels in blood or other biological fluids. Glycine is one of the essential amino acids and plays a vital role in many biological processes, including protein synthesis, supporting nervous system function, and contributing to collagen production. This test is important for evaluating metabolic disorders, such as abnormal metabolic conditions that may affect amino acid levels in the body. It can also help diagnose and monitor specific health conditions, such as kidney diseases or genetic disorders related to amino acid metabolism. The analysis provides precise data that helps physicians make appropriate treatment decisions and support effective patient care.
