A. It differs in several ways. First, the sample types we typically use (red blood cells or dried blood spots versus whole plasma or plasma phospholipids). Each of these sample types has a unique fatty acid profile, so you cannot compare the EPA+DHA level in RBCs to...

Yes, we follow Good Laboratory Practices. All of our assays are validated. In particular for plasma/serum total and free (i.e., unbound) concentrations of EPA, DHA, DPA and ARA have been validated per the Guidance for Industry: Bioanalytical Method Evaluation (FDA;...

Any biological sample that contains fatty acids. Typically we are asked to analyze human plasma or erythrocytes, but we have experience with whole blood, plasma lipid classes (TG, CE, PL, NEFA), lipoproteins (VLDL, LDL, HDL), lipoprotein lipid classes, tissues...

It depends on the sample type, but our typical assays require < 25 uL of plasma or blood or RBCs, or about 25 mg of tissues. We prefer to receive aliquots of at least 200 uL for liquid samples. If dried spots are preferred, 25 uL of whole blood or of RBCs mixed...
