Bellwether Baseline Panel

Every marker in your yearly baseline is chosen by Bellwether's clinical science group, so a single draw tells the fullest story your blood can tell.

What the draw covers

Heart Health Thyroid Immunity Ovarian Health Prostate Health Metabolism Nutrients
Liver Health Kidney Health Heavy Metals Electrolytes Blood Count Inflammation

Every test folded into your yearly membership

Aging Signals

Cellular Age

Cellular Age estimates how your body is wearing relative to people born the same year. We read a cluster of blood markers with long-observed ties to aging through an open, peer-reviewed clock built by the Rennick Aging Group.

Aging Velocity
Composite Score

Cardiovascular

Creatine Kinase (CK)

An enzyme stored in muscle tissue. When it shows up in high amounts in blood it usually means muscle fibres have been strained — often simply from hard training in the days before a draw.

Lipoprotein(a)
Apolipoprotein B (ApoB)
Triglycerides
LDL Cholesterol
HDL Cholesterol
Cholesterol / HDL Ratio
Total Cholesterol
VLDL Cholesterol

Thyroid Function

Thyroid-Stimulating Hormone (TSH)

The courier molecule that tells your thyroid how hard to work. Readings at either end of the range hint at a gland running slow or running hot.

Thyroxine (T4), Free
Triiodothyronine (T3), Free
Reverse T3*

Immune Balance

Neutrophils

The most numerous white blood cell and the first crew on scene when bacteria get in or tissue is torn.

Monocytes
Basophils
White Blood Cells (WBC)
Lymphocytes
Eosinophils

Endocrine Panel

Testosterone, Total

The full circulating amount of the hormone behind muscle upkeep, bone density, drive and reproductive function in every body.

Estradiol (E2)
Follicle Stimulating Hormone (FSH)*
Cortisol
Testosterone, Free
Progesterone*
Luteinizing Hormone (LH)*
Prolactin*

Metabolic Function

Uric Acid

Left behind when the body breaks down purines in food. When it builds up it can crystallise in joints or tax the kidneys.

Hemoglobin A1c (HbA1c)
Glucose
Insulin

Micronutrients

Vitamin B12*

Needed to build red blood cells, keep nerve signalling clean, and copy DNA correctly during cell division.

Vitamin D
Iron
Iron % Saturation
Ferritin
Folate

Liver Function

Gamma-Glutamyl Transferase (GGT)

An enzyme that reflects how the liver and bile ducts are coping. It climbs early when either is under load, which makes it a useful first flag.

Albumin
Aspartate Transaminase (AST)
Alkaline Phosphatase (ALP)
Total Protein
Total Bilirubin
Alanine Aminotransferase (ALT)
Globulin

Kidney Function

Blood Urea Nitrogen (BUN)

Measures the nitrogen waste left in blood after protein is broken down, which shows how efficiently your kidneys are clearing it.

BUN / Creatinine Ratio
Albumin / Globulin Ratio
Potassium
Estimated Glomerular Filtration Rate (eGFR)
Creatinine
Sodium
Calcium

Heavy Metals & Electrolytes

Calcium

Essential for bone strength, muscle contraction and nerve signalling, and tightly regulated by the body at all times.

Chloride
Sodium
Carbon Dioxide
Magnesium
Mercury*

Inflammation

Homocysteine

An amino acid that piles up when B-vitamin pathways stall. Sustained high readings are linked to strain on blood vessel walls.

High-Sensitivity C-Reactive Protein (hsCRP)
Uric Acid

Blood Count

Total Iron-Binding Capacity (TIBC)

Shows how much iron your blood is able to carry at once — the practical ceiling on delivering oxygen to working tissue.

Red Blood Cell (RBC) Count
Hematocrit
Mean Corpuscular Hemoglobin Concentration (MCHC)
Red Cell Distribution Width (RDW)
Mean Corpuscular Volume (MCV)
Hemoglobin
Platelet Count

*Please note: FSH, LH, progesterone, prolactin, reverse T3 and mercury are not yet drawn for Bellwether members living in Rhode Island.

Bellwether is built for prevention-led testing and follow-through. It is not designed for urgent or emergency care.

You will have a Bellwether care team, and the yearly membership is meant to sit alongside a primary care doctor rather than take their place.

We are glad to pass results on to any outside clinician you work with so nothing about your care gets fragmented.
