More direction for your health. Less noise.

Every core area covered to provide the full picture

Your first test spans all eight core health areas - heart, metabolism, hormones, and more. Your next tests narrow in on what matters for you.

Health tracking that adapts to you

All testing adapts to your results and focus areas. Each phase provides clear next steps for your health.

A doctor helps you find the focus

A Thriva doctor reviews every result, and you can talk through what’s next in a video consultation.

Health isn’t about tracking everything. It’s about tracking what matters and making small, sustainable changes.

The single source of truth for your health

Your blood test results, wearable data and health history in one record, so you can see what’s changing without piecing it together across apps.

What your first test covers

Start with a detailed picture of where your health stands today. Covering 33 markers — each one chosen because it tells us something useful about how your body is working right now.

Lipids

11 markers

Lipids are the fats and cholesterol your body uses to build cells and store energy. Their balance is a strong predictor of long-term heart and blood vessel health.

Cholesterol

HDL cholesterol

LDL cholesterol

Non-HDL cholesterol

Triglycerides

Triglyceride/HDL ratio

Total cholesterol/HDL ratio

Apolipoprotein A1

Apolipoprotein B

ApoB:ApoA ratio

Lipoprotein(a)

Blood sugar

1 marker

Your average blood sugar over recent months is a core measure of metabolic health. Persistently raised levels are an early signal of insulin resistance and type 2 diabetes risk.

HbA1c

Kidney function

3 markers

Your kidneys filter waste, balance fluids, and help regulate your blood pressure around the clock. These markers can flag changes before symptoms show up.

Uric acid

Creatinine

Estimated glomerular filtration rate (eGFR)

Sex hormones

4 markers

Sex hormones shape your energy, mood, libido, and muscle and bone strength. Tracking them gives context for changes you can feel but can't always explain.

Testosterone

Testosterone profile (free or unbound)

Free androgen index

SHBG

Micronutrients

4 markers

Micronutrients are the vitamins, minerals, and fatty acids your body needs daily but can't make itself. Even small shortfalls can drain your energy, immunity, and focus.

Active B12

Folate

Ferritin

Vitamin D

Liver function

7 markers

Your liver handles hundreds of jobs, from processing food and drink to clearing out toxins. These markers show how well it's coping with the workload.

Alanine transferase

Alkaline phosphatase

Gamma-GT

Bilirubin

Albumin

Globulin

Total protein

Thyroid function

2 markers

Your thyroid sets the pace your body runs at — affecting energy, weight, mood, and temperature. Small imbalances can leave you feeling flat, foggy, or out of sync.

Thyroid-stimulating hormone (TSH)

Free thyroxine (FT4)

Inflammation

1 marker

Inflammation is your immune system at work. Short bursts protect you, but low-level chronic inflammation is linked to long-term disease — and this is your clearest window into it.
