Elevated Plasma VLCFA Levels
Abnormally high concentrations of unbranched very long-chain fatty acids, indicating a peroxisomal beta-oxidation defect.
A blood sample is analyzed using gas chromatography-mass spectrometry to measure the concentrations of specific fatty acids. The test specifically looks for elevated levels of C24 and C26 fatty acids relative to C22.
