The longevity glossary.

What the tests, treatments, and consultations on offer at longevity clinics actually are, in plain language. Definitions only, with no claim about whether any of them works: that question is answered on the protocol pages, where the evidence is graded.

A

Advanced lipid panelDiagnostic: Measures ApoB and lipoprotein(a) alongside a standard lipid profile. Both are markers of cardiovascular risk that a routine cholesterol test does not report.

B

Biological age testingDiagnostic: Estimates a biological age from DNA methylation patterns and reports it against chronological age. Different laboratories use different clocks, so results are not directly comparable between providers.

C

Comprehensive biomarker panelDiagnostic: A blood panel covering metabolic, lipid, inflammatory, hormonal and organ-function markers in one draw, reported together rather than as separate tests.
Continuous glucose monitoringDiagnostic: A wearable sensor recording interstitial glucose continuously for one to two weeks, showing the response to meals, sleep and activity rather than a single fasting figure.
Contrast therapyTherapy: Alternating heat and cold exposure in one session, usually sauna paired with cold immersion.

D

DEXA body composition scanDiagnostic: A low-dose X-ray scan reporting fat mass, lean mass and bone mineral density by body region.
Dry flotationTherapy: A session lying on a membrane suspended over warm water, giving the sensation of floating without contact with the water.

E

Executive health screeningDiagnostic: A scheduled programme bundling bloods, imaging, functional testing and a consultation, usually completed in one visit with a written report.

F

Functional medicine consultationConsult: A consultation model organised around systems and root-cause framing. Functional medicine certification is separate from, and not a substitute for, medical registration.

G

Genomic testingDiagnostic: Sequences selected genes or the whole genome to report inherited disease risk variants and pharmacogenomic markers.
GLP-1 receptor agonist therapyIntervention: Prescribes semaglutide, tirzepatide or a related agent for weight and metabolic management, with clinical monitoring. These are prescription-only medicines in both markets.
Gut microbiome testingDiagnostic: Sequences bacterial DNA in a stool sample to describe the composition of the gut microbiome. Clinical interpretation of these profiles is still developing.

H

Hormone optimisationIntervention: Assesses and treats sex and thyroid hormone levels, including menopausal hormone therapy and testosterone replacement, under prescription and monitoring.
Hyperbaric oxygen therapyTherapy: Breathing oxygen at above atmospheric pressure in a sealed chamber, in repeated sessions. Approved indications are narrow in both markets and do not include general healthy ageing.

I

ImmunotherapyIntervention: Treatments that modulate immune function. Coverage of this term varies widely between clinics, from licensed oncology protocols to unapproved immune-modulating infusions.
Intravenous nutrient therapyIntervention: Delivers vitamins, minerals or amino acids intravenously, usually as a scheduled infusion.

L

Liquid biopsy cancer screeningDiagnostic: A blood test looking for circulating tumour DNA to screen for cancer before symptoms. Sensitivity varies substantially by cancer type and stage.
Longevity physician consultationConsult: Clinician time to review results and agree a plan. Whether that clinician is registered with SMC or AHPRA is recorded separately on each person profile.

N

NAD+ and precursor therapyIntervention: Administers NAD+ intravenously, or its precursors NMN or NR orally, to raise NAD+ availability. Regulatory status of the precursors differs between Singapore and Australia.
Nutrition and dieteticsConsult: Dietary assessment and planning with a dietitian or nutritionist. Dietitian is a protected title in Australia; nutritionist is not.

P

PEMF therapyTherapy: Applies pulsed electromagnetic fields to the body via a mat or coil.
Peptide therapyIntervention: Prescribes short amino-acid chains for signalling effects. Many peptides used in this setting are unapproved for the indication in one or both markets, so the regulatory position matters case by case.

R

Red light therapyTherapy: Exposure to red and near-infrared light from panels or beds, in repeated sessions.

S

Sleep studyDiagnostic: Records breathing, oxygen saturation, heart rate and movement overnight, at home or in a laboratory, to identify sleep-disordered breathing.
Stem cell therapyIntervention: Administers cell preparations, usually mesenchymal stromal cells. Tightly restricted in both markets: Australia limits autologous cell treatments and Singapore regulates them as advanced therapy products.

T

Telehealth consultationConsult: Consultation by video or phone rather than in person, which is how nationally available operators reach patients outside their clinic city.

V

VO2 max testingDiagnostic: Measures maximum oxygen uptake during graded exercise while breath gases are analysed, reported as a cardiorespiratory fitness figure.

W

Whole-body cryotherapyTherapy: Brief exposure of the whole body to very low air temperature, typically two to three minutes in a chamber.
Whole-body MRIDiagnostic: A non-contrast scan of the body used to look for structural abnormality. Screening asymptomatic people this way is contested: it finds incidental results that often need follow-up.

A definition is not an endorsement. Where a treatment has been graded, the protocol page carries the evidence and the regulator position.
