Porphyrins, Quantitative, Random Urine, LabCorp

Optimal range:   0 - 20 ug/L

Porphyrins are a group of compounds defined by their chemical structure. These compounds are by-products of heme synthesis and are normally present at low levels in blood and other body fluids. Porphyrin tests measure porphyrins and their precursors in urine, blood, and/or stool.

Bile Acids, Fractionated LCMS, LabCorp

Optimal range:   0 - 1.9 umol/L

Ursodeoxycholic acid (UDCA) is a naturally occurring bile acid that has been extensively studied and utilized in the treatment of various liver and gallbladder conditions. It is particularly effective in managing cholestatic liver diseases, where bile flow is impaired, leading to the accumulation of bile acids in the liver.

Vaccenic acid (VA) is a monounsaturated omega-7 fatty acid (18:1n7).

VA is a naturally occurring trans-fat unlike those produced industrially. The trans-configuration occurs around carbon 11, therefore VA is sometimes denoted as trans11-18:1n7. Ruminant animals produce vaccenic acid in a fermentation process in their microbiome. The dairy products (cheese, milk, butter) or meat obtained from these animals contain VA. There is also a cis-configuration of vaccenic acid created by de novo lipogenesis.

Valerate is a Short Chain Fatty Acid (SCFA). It is derived from bacterial fermentation of protein in the distal colon.

SCFAs are the end product of the bacterial fermentation process of dietary fiber by beneficial flora in the gut and play an important role in the health of the GI as well as protecting against intestinal dysbiosis.

Optimal range:   178 - 377 umol/L

Branched Chain Amino Acids (Isoleucine, Leucine, Valine) Isoleucine, leucine and valine are the three branched chain amino acids (BCAAs). Branched chain amino acids (BCAA) are essential amino acids and must be obtained from the diet (mainly meat, grains, and dairy).

NutrEval Plasma - Urine and Blood, Genova Diagnostics

Optimal range:   18.3 - 42.6 Units

Branched Chain Amino Acids (Isoleucine, Leucine, Valine) Isoleucine, leucine and valine are the three branched chain amino acids (BCAAs).

Branched chain amino acids (BCAA) are essential amino acids and must be obtained from the diet (mainly meat, grains, and dairy). 

Not only do the BCAAs account for almost 50% of muscle protein, but they have many metabolic functions. 

BCAAs act as substrates for protein synthesis, energy production, neurotransmitter production, glucose metabolism, and the immune response. They are also involved in stimulation of albumin and glycogen synthesis, improvement of insulin resistance, inhibition of free radical production, and hepatocyte apoptosis with liver regeneration.
