What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

D- and L-2-hydroxyglutarate panel - DBS

D- & L-2-hydroxyglutarate panel

This panel contains results for D-2-hydroxyglutarate (D-2-HG) and L-2-hydroxyglutarate (L-2-HG), the isomeric forms of 2-hydroxyglutaric acid. Accumulation of D-2-HG and/or L-2-HG in body fluids (e.g. urine, CSF, amniotic fluid, blood, plasma) are the biochemical hallmarks of 2-hydroxyglutaric acidurias (2-HGAs), inborn organic acidurias that cause neurological impairment at a young age.[PMID22391998] Results of this panel are used to differentiate D-2-HGA, L-2-HGA and D,L-2-HGA.
