Lipids & Heart Health

Cholesterol, triglycerides, and cardiovascular risk markers

5

LDL (low-density lipoprotein) carries cholesterol to your arteries.

ApoB measures the total number of atherogenic (artery-clogging) particles in your blood.

Total Cholesterol

Total cholesterol is a legacy aggregate metric — the sum of LDL, HDL, and VLDL cholesterol, typically estimated via the Friedewald equation (Total = LDL + HDL + Triglycerides/5).

HDL (high-density lipoprotein) participates in reverse cholesterol transport — moving cholesterol from arterial walls back to the liver for excretion.

Triglycerides are the most common type of fat in your blood.

Metabolic Health

Blood sugar, insulin resistance, and metabolic function

4

HbA1c measures your average blood sugar over the past 2-3 months by reflecting the percentage of hemoglobin with glucose attached.

Fasting glucose measures blood sugar after 8+ hours of fasting.

Fasting insulin is one of the earliest markers of metabolic dysfunction.

Uric acid is a waste product from purine metabolism.

Thyroid Function

Thyroid hormones and autoimmune markers

2

TSH controls thyroid hormone production.

Free T4 (thyroxine) is the inactive thyroid hormone that converts to T3 (the active form) in tissues.

Hormones

Reproductive, stress, and growth hormones

1

Testosterone is the primary male sex hormone, critical for muscle mass, bone density, mood, and energy.

Liver Function

Enzymes, proteins, and liver health

3

AST is a liver enzyme also found in the heart, muscles, and kidneys.

ALT is the most liver-specific enzyme.

Albumin is the most abundant protein in your blood, made by the liver.

Kidney Function

Filtration, waste clearance, and kidney health

2

Creatinine is a waste product from muscle metabolism, filtered out by the kidneys.

eGFR estimates how well your kidneys filter waste from blood.

Inflammation

Systemic inflammation and immune markers

2

High-sensitivity CRP measures systemic inflammation — a central driver of biological aging known as "inflammaging.

Homocysteine is an amino acid produced during protein metabolism.

Blood Cells

Red cells, white cells, and platelet health

2

Hemoglobin is the protein in red blood cells that carries oxygen throughout your body.

Platelets are small blood cells that form clots to stop bleeding.

Vitamins & Minerals

Nutrient status and deficiency markers

7

Vitamin D is essential for bone health, immune function, mood regulation, and — emerging research shows — genomic stability and telomere preservation.

Serum iron measures the amount of iron circulating in your blood.

Ferritin is the best single marker of your body's iron stores.

Vitamin B12 is essential for nerve function, DNA synthesis, and red blood cell production.

Magnesium is a critical mineral involved in over 300 enzymatic reactions: energy production, muscle/nerve function, blood sugar regulation, and blood pressure control.

Folate (vitamin B9) is essential for DNA synthesis, cell division, and red blood cell production.

Zinc is an essential trace mineral involved in immune function, wound healing, protein synthesis, DNA synthesis, and testosterone production.

Electrolytes

Essential minerals for nerve, muscle, and fluid balance

2

Serum calcium is tightly regulated by the body — even small deviations can be significant.

Potassium is the most abundant intracellular electrolyte.
