Test ID: AACSF
Amino Acids, Quantitative, Spinal Fluid
NY State Approved 
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Useful For Suggests clinical disorders or settings where the test may be helpful
Evaluating patients with possible inborn errors of amino acid metabolism, in particular nonketotic hyperglycemia and serine biosynthesis defects, especially when used in conjunction with concomitantly drawn plasma specimens
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
This test must be ordered in conjunction with AAQP/9265 Amino Acids, Quantitative, Plasma. The specimens for both tests AAQP/9265 Amino Acids, Quantitative, Plasma and AACSF/81934 Amino Acids, Quantitative, Spinal Fluid) must be collected at the same time.
