The original biological aging test

FDX 501

How well are you ageing? It is what is on the inside that counts!

Biological ageing is related to the health and function of our bodies at cellular level. By using the most advanced glycan biomarkers to access the state of our internal environment, we can identify the advancement of negative biochemical activity such as inflammageing on health status.

GlycanAge technology measures immunoglobulin G glycans (IgG), which are responsible for humoral immunity; including specific antigen binding for antigen neutralization, complement activation, target opsonization for phagocytosis, antibody-dependent cell-mediated cytotoxicity and hypersensitivity reactions.

Depending on the antigen the antibody is specific to, it can be involved either in protection from pathogens (in case of harmful non-self-antigens), or in damaging reactions such as autoimmune diseases (in case of self-antigens) and anaphylaxis (in case of non-harmful non-self-antigens).

GlycanAge looks at ageing on a systemic level, through functional effectors that play a key role in our immune system (to promote or suppress inflammation) which contribute to inflammageing (ageing of our immune system). 

GlycanAge is the first biological age test that has proven responsiveness to interventions that beneficially affect the biology of ageing. Using this test in conjunction with FunctionalDX to maximise your therapeutic interventions; personalise, prioritise and progress your client’s health to the next level, reverse the aging process, reduce the affects of dis-function and heal the body for optimal health.

Why are we asking for the patients’ ethnicity?

We collect your ethnicity to plot you to the closest demographic cohort. Ethnicity takes into account your genetics, but is also influenced by your lifestyle, culture, geographic area and socioeconomic status. All of these, combined, affect your health risks.

Suitable for:

  • Those looking to understand their biological age vs chronological age
  • Those interested in ageing well and looking to future proof their health and wellbeing / reduce the ageing process
  • For those with previous diagnosis interested to understand how their current state of health affects their cellular ageing
  • Those with or suspected conditions or symptoms that suggest inflammatory or metabolic concerns, immune and cardiovascular disorders, changes to memory, energy, cognition, and weight.

Functional DX to me is the 'Go to Test' that I would use for patients before anything else
