FATTY ACIDS, profile
fP-FA ATK 8018
Diet plays a significant role in shaping the composition of plasma fatty acids. The composition of fatty acids in cell membranes is accurately mirrored by the plasma fatty acid profile. This profile has a pivotal impact on various functions of cell membranes.
Indications
Determining abnormalities in plasma fatty acid content or monitoring fatty acid treatment.
Preparation
A 12-hour fasting period is necessary. You are allowed to consume a glass of water and take your regular medications. Refrain from consuming fatty acid preparations for the duration of the 12-hour fasting period.
Sample
1.0 mL fasting EDTA or Li-heparin plasma (minimum 0.5 mL)
Storage and delivery
Delivery at room temperature on the sampling day (Mon-Thu) if it arrives the next day. Can be stored refrigerated over the weekend, ship at room temperature.
Method principle
Gas chromatography (GC)
Turnaround time
10 weekdays
