About This Test
Very Long Chain Fatty Acids (VLCFAs), Phytanic acid and Pristanic acid are metabolized by Peroxisomes. Defects in these pathways usually result in the accumulation in tissues and body fluids of one or more metabolites derived from the blocked metabolic steps. This assay is used for differential diagnosis of peroxisomal disorders like Zellweger spectrum disorders of peroxisomal biogenesis, X-linked Adrenoleukodystrophy (X-ALD) and its adult form X-linked Adrenomyeloneuropathy (X-AMN), Refsum disease (Phytanoyl-CoA hydroxylase Deficiency) & 2-methylacyl-CoA racemase deficiency.

Frequently Asked Questions
Outsourced test are being done from Dr. Lal Path Lab. Charges and reporting time is same as of Dr. Lal Path Labs.
Overnight fasting is mandatory. For pediatric patients, fasting is not required but sample collection should occur prior to the next meal or scheduled feeding.
The Very Long Chain Fatty Acids (VLCFA) test is important because it helps detect rare but serious inherited metabolic and neurological disorders, especially peroxisomal disorders, at an early stage—allowing timely treatment, genetic counseling, and family screening.
TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
