Gliadin is a glycoprotein. It is an alcohol-soluble protein present in wheat and occurring in various forms (a-, g-, and w-gliadins). g-Gliadins-15-mer are considered to be the most ancient of the gluten family. This group of gliadins works with gluten proteins to determine the functional properties of wheat flour.

Known Cross-Reactions: Cerebellar

Gamma-Glutamyl Transferase (GGT) is an enzyme most commonly associated with the liver. GGT tests are often run to determine the cause and extent of liver damage or to monitor treatment of alcohol abuse disorders. While an elevated GGT score may be a cause for concern, a normal or low score is generally not.

Gamma-tocopherol is part of the Vitamin E classification group.

The term vitamin E refers to a group of eight naturally occurring compounds, all with different potencies:

– alpha-, beta-, gamma- and delta-tocopherol and

– alpha-, beta-, gamma- and delta-tocotrienol.

Gammaglobulin A refers to the portion of the gamma globulin protein fraction that includes Immunoglobulin A (IgA), a key antibody involved in immune defense. IgA is primarily found in mucosal areas such as the respiratory and gastrointestinal tracts, as well as in secretions like saliva, tears, and breast milk. It plays a crucial role in neutralizing pathogens at mucosal surfaces, helping prevent infections before they enter the bloodstream. While the term "gammaglobulin A" is sometimes used interchangeably with IgA, it more broadly reflects the presence of IgA within the gamma globulin class of serum proteins. Abnormal levels of gammaglobulin A—or more specifically, IgA—may indicate immune disorders, chronic infections, or certain inflammatory conditions.

Gamma globulin G, more precisely known as Immunoglobulin G (IgG), is the most abundant type of antibody in the human body, accounting for approximately 75% of all serum immunoglobulins. As a key component of the gamma globulin fraction of blood proteins, IgG plays a critical role in the immune system's defense against bacterial and viral infections. It is produced by plasma cells and circulates in the blood and extracellular fluid, where it recognizes and binds to specific antigens, marking them for destruction by other immune cells. IgG is also the only antibody class that can cross the placenta, providing passive immunity to newborns. Clinically, IgG levels are often measured to assess immune function or to diagnose conditions such as immunodeficiencies, chronic infections, or autoimmune diseases.

Gamma globulin M, more accurately referred to as immunoglobulin M (IgM), is the first type of antibody produced by the immune system in response to an infection. It is a part of the gamma globulin fraction of serum proteins and plays a critical role in the body’s initial defense against pathogens. IgM is primarily found in the blood and lymphatic fluid, and because of its large size, it is especially effective at forming complexes with antigens and activating the complement system. Elevated levels of IgM can indicate recent or acute infections, autoimmune disorders, or certain types of blood cancers, while low levels may suggest immune deficiencies. As the immune response progresses, IgM is typically replaced by other immunoglobulins such as IgG, which provide longer-lasting immunity.

Elevated antibody levels can be clinically significant — while the antibodies themselves don’t destroy anything, they do trigger an inflammatory response that can cause significant destruction of tissue and resulting symptoms. This response is not necessarily dependent on antibody levels. However, an equivocal result may mean you are just beginning to exhibit an immune reaction, so this is an important time to take measures to support the body in damping immune reactivity.

Gardnerella vaginalis is a type of bacteria that is commonly found in the vaginal flora of some women. While it can be present in the vagina without causing any issues, it is often associated with bacterial vaginosis (BV), a condition that occurs when the natural balance of bacteria in the vagina is disrupted. BV can lead to symptoms such as unusual discharge, a fishy odor, and vaginal irritation, although some women may not experience any symptoms. Gardnerella vaginalis plays a key role in this imbalance because its overgrowth can reduce the number of "good" bacteria like lactobacilli, which normally help maintain a healthy vaginal environment. BV is not considered a sexually transmitted infection (STI), but it is more common in sexually active women. It is usually treated with antibiotics to restore the normal bacterial balance.

This marker is usually part of a test called IBD Expanded Panel (IBD = Inflammatory Bowel Disease) and aids in the diagnosis of inflammatory bowel disease and the differential diagnosis of Crohn’s disease (CD) and ulcerative colitis (UC); it is also a prognostic aid for clinical management of patients with CD.

The Gastrin test is a simple blood test that checks for excess gastrin production. Gastrin is a hormone your stomach makes to fuel the release of gastric acid. Your body needs this to digest and absorb nutrients in your food, particularly proteins and amino acids. 

Gastric acid is found inside cells called G cells. These are located in your stomach lining and the lining of your upper small intestine.
