High-sensitivity C-reactive protein; a sensitive marker of systemic inflammation and a strong predictor of cardiovascular disease risk.

The Neutrophil-to-Lymphocyte Ratio (NLR) is one of the most powerful emerging inflammaging markers. It predicts all-cause mortality, cardiovascular events, and cancer prognosis. Optimal: 1.0–2.5. Above 3.0 indicates elevated inflammation. Above 5.0 is associated with significantly increased mortality risk.

The Lymphocyte-to-Monocyte Ratio (LMR) reflects immune reserve and immunosenescence. Low LMR predicts worse cancer outcomes and immune dysfunction. Optimal: above 4.0. Below 2.0 signals low immune reserve.

The Platelet-to-Lymphocyte Ratio (PLR) is a systemic inflammatory marker from a standard blood count. Elevated PLR (>150) predicts cardiovascular events, cancer mortality, and sepsis risk.

The Systemic Immune-Inflammation Index (SII) combines neutrophils, platelets, and lymphocytes into a single inflammaging score (JAMA Network Open, 2022). Optimal: below 500. High risk: above 1000.

Your stored-iron reserve — also rises with inflammation, so it's read alongside the ratios above.

An essential trace mineral and antioxidant cofactor — supports thyroid-hormone conversion and your glutathione defence system.

Serum iron — complements ferritin for iron status. Fluctuates significantly, always measure fasting.

Iron transport protein — elevated in iron deficiency, decreased in inflammation and liver disease.

A fat-soluble vitamin critical for calcium absorption, bone health, immune function, and mood regulation; widespread deficiency affects billions globally.

Essential for nerve function, DNA synthesis, and red blood cell formation; deficiency is common in vegans and older adults and can cause irreversible neurological damage.

A B-vitamin essential for DNA synthesis, red blood cell formation, and preventing neural tube defects during pregnancy.

Transferrin Saturation (TSAT) is far more informative than ferritin alone for diagnosing both iron deficiency and iron overload (haemochromatosis). Optimal: 20–45%. Below 16% indicates iron deficiency even when ferritin appears normal. Above 50% is a haemochromatosis screening threshold.

Urinary iodine reflects the body's iodine status, an essential trace element required for thyroid hormone production. Both deficiency and excess can impair thyroid function and overall health.

A trace mineral vital for immune defence, wound healing, testosterone production, and hundreds of enzymatic processes throughout the body.

Serum calcium — regulated by parathyroid hormone and vitamin D. Important for bones, muscles, nerve conduction and heart rhythm. 9.0–10.0 mg/dL optimal.

An essential mineral involved in over 300 enzymatic reactions, including energy production, muscle function, and nervous system regulation.

Insulin-like growth factor 1; reflects growth hormone activity and is important for muscle maintenance, metabolism, and healthy ageing.

Dehydroepiandrosterone sulfate — adrenal hormone, precursor to testosterone and estrogen. Declines with age, considered a marker of biological aging.

The key hormone for muscle, drive and mood. The optimal band sits well above the lab's "normal" floor.

The biologically active fraction of testosterone not bound to proteins; more clinically relevant than total testosterone for assessing hormonal status.

Sex hormone-binding globulin (SHBG) is a protein produced by the liver that binds testosterone and estradiol, regulating the amount of free (active) hormone available to tissues. Higher SHBG means less free testosterone and estradiol. SHBG levels are influenced by age, BMI, insulin resistance, thyroid function, and liver health. Low SHBG is associated with metabolic syndrome and type 2 diabetes; very high SHBG can cause symptoms of hormone deficiency despite normal total levels.

Morning cortisol — adrenal stress hormone. 8–18 µg/dL optimal. Chronically elevated = catabolic, muscle loss, immune suppression. Too low = adrenal insufficiency.

Body weight is a fundamental health parameter evaluated alongside height and body composition. Maintaining a healthy weight reduces the risk of cardiovascular disease, type 2 diabetes, and other chronic conditions.

GrimAge v2 is an epigenetic clock that estimates a person's biological age based on DNA methylation patterns, and is one of the strongest predictors of lifespan and age-related disease risk. A biological age lower than chronological age indicates healthier aging and a reduced risk of mortality.

PhenoAge is a biological age calculated from 9 standard blood markers using the Levine algorithm (Yale, 2018). It predicts all-cause mortality more accurately than chronological age. A PhenoAge lower than your calendar age indicates slower biological aging. Each +1 year above chronological age is associated with ~6% increased mortality risk.

Biological age calculated from a multi-marker blood panel using the Bortz 2023 Elastic-Net Cox model. Gives a second-perspective bio-age alongside PhenoAge — different methodology from the same draw.

Epigenetic clock — measures the pace of biological aging. <0.9 = aging slower than calendar, 1.0 = normal, >1.2 = accelerated aging. Based on DNA methylation.
