FFA (Free Fatty Acids) NEFA

Analyte: Non-esterified Free Fatty Acid
Specimen Type: Serum (fasting recommended); Inquire for addiitional option(s)
Biological or Clinical Significance:

Fatty acids are straight-chain carboxylic acids (either saturated or unsaturated). They are derived from the hydrolysis of fats or can be synthesized from two carbon units (acetyl- or malonyl-CoA) in the liver,...

Glycerol, Free

Analyte: Glycerol
Specimen Type: Serum, EDTA Plasma, Heparin Plasma
Biological or Clinical Significance:

Glycerol (Glycerin, glycerine or 1,2,3-propanetriol) is a three-carbon alcohol that contains a hydroxyl group on each of its carbon atoms. Chemically, it is possible to esterify each hydroxyl group with a fatty...

Phospholipids, Total

Analyte: Phospholipids, Total
Specimen Type: Serum, EDTA Plasma
Biological or Clinical Significance:

Serum phospholipids are formed in the liver, where they and other lipid components associate with apolipoproteins to produce lipoproteins. Determination of serum phospholipids may be helpful in diagnosis or clinical...

Triglycerides, Total (w/o Glycerol Correction)

Analyte: Triglycerides Total
Specimen Type: Serum, Inquire for additional option(s)
Biological or Clinical Significance:

Triglycerides are the major form of fat found in nature, and their primary function is to provide energy for the cells.  Because of their water insolubility, triglycerides are transported in the plasma in...
