Test ID: POXP    
Fatty Acid Profile, Peroxisomal (C22-C26), Plasma

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluating patients with possible peroxisomal disorders, including peroxisomal biogenesis disorders, X-linked adrenoleukodystrophy, and Refsum disease using plasma specimens

 

Aiding in the assessment of peroxisomal function

Highlights

This test analyzes very long-chain fatty acids as well as pristanic and phytanic acid to aid in diagnosis of peroxisomal biogenesis disorders, X-linked adrenoleukodystrophy (X-ALD), and Refsum disease.

 

Reports include concentrations of C22:0, C24:0, C26:0 species, phytanic acid and pristanic acid, and calculated C24:0/C22:0, C26:0/C22:0, and phytanic acid:pristanic acid ratios.

 

This test is also appropriate for follow-up of an abnormal newborn screen for X-ALD.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
