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.

Order vs observation: Both
Method: [9,10-3H] palmitate substrate

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Acyl CoA dehydrogenases [Enzymatic activity/mass] in Fibroblast by [9,10-3H] palmitate substrate

Acyl CoA dehydrogenases

Fatty acid oxidation in medium- or long-chain acyl CoA dehydrogenase deficiencies can be measured by quantifying the release of 3H2O from (9,10-3H) palmitate (this term) and myristate [LOINC78360-5] substrates added to cultured fibroblast. [PMID: 2109149] Fatty acid (i.e. palmitate or myristate) oxidation rates by fibroblasts are expressed as nanomole of 3H fatty acid (3H FA) oxidized per hour per milligram of cell protein (nmol 3H FA/h/mg protein).[PMID: 12840153]
