Sarcosine is an amino acid made within the methylation cycle when S-adenosylmethionine (SAM) is conjugated with glycine. It can also be made by catabolism of dimethylglycine (DMG).
There are many dietary sources of sarcosine including eggs, legumes, nuts, and meats.
Sarcosine is also available as an over-the-counter supplement, and it is widely used in cosmetic formulations (toothpaste, creams, and soaps) and detergents. In the methylation cycle, sarcosine is created by the GNMT enzyme, which functions to control SAM excess.

In the methylation cycle, sarcosine is created by the GNMT enzyme, which functions to control SAM excess. Some clinicians use sarcosine elevation as a marker of ‘excess methyl supplementation’ or ‘over-methylation.’ Currently, there is no literature to support this hypothesis, but rather it is based on physiology.

Sarcosine is also known as N-methylglycine. It is an intermediate and byproduct in the glycine synthesis and degradation. Sarcosine is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates sarcosine from glycine.

The SARS-CoV-2 IgG assay is intended for qualitative and semi-quantitative detection of IgG antibodies to the S1 receptor binding domain (RBD) of the SARS-CoV-2 spike protein. The measurement of IgG levels can provide insight to an individual's adaptive immune response to a SARS-CoV-2 infection or vaccination. Although the assay is designed to assess the level of an individual's immune response, studies are still needed to determine the index level threshold that confers protective immunity as well as how long the adaptive immune response may last post-infection or via vaccination.
Optimal range: 0 - 13 AU/mL
The SARS-CoV-2 Semi-Quantitative IgG Antibody test is a blood test that measures the level of IgG antibodies your body has produced in response to the SARS-CoV-2 virus, the virus responsible for COVID-19. Unlike a qualitative test that gives a simple “positive” or “negative” result, this semi-quantitative test estimates the amount of antibody present and provides a numerical value — giving more detailed insight into your immune system’s response.

Aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection.
Optimal range: 0.8 - 25000 U/mL
The SARS-CoV-2 Spike Antibody Dilution test measures the concentration of IgG antibodies against the virus’s spike protein, providing a more precise view of your immune response than a simple positive/negative result. These antibodies usually appear after vaccination or past COVID-19 infection, and dilution testing is used when levels are too high for standard tests to measure accurately. A higher result generally reflects a stronger antibody presence, which may support faster immune recognition and a lower risk of severe illness, though protection varies by individual and variant. This test cannot tell you when exposure occurred, how long immunity will last, or whether you currently have COVID-19. Instead, it confirms immune recognition and offers valuable insight into your body’s response, while reminding that antibody levels are just one piece of your overall defense system.
Reference range: Negative, Positive
The SARS-CoV-2 Spike Ab Interp refers to the interpretation of antibodies directed against the spike (S) protein of the virus that causes COVID-19. This marker is typically included in antibody panels to evaluate your immune response following infection with SARS-CoV-2 or after vaccination with COVID-19 vaccines that target the spike protein (such as Pfizer-BioNTech, Moderna, or Novavax).
This test does not measure the antibody level itself, but instead provides an interpretation (positive, negative, equivocal) based on whether spike-specific antibodies are detected in your blood.
