This is the test to start with if you do not have one specific question. It looks at thyroid function, vitamin D, B12, cortisol, magnesium and CRP for inflammation, alongside cholesterol, kidney markers and blood proteins.
Your report explains where each reading sits and what the marker reflects, so you have something concrete to work from.
Your result, the lab reference range and an explanation of what each marker reflects. See how a reading is shown and what to look at next.
Your results stay in your Helvy account. Keep your first test as a baseline and compare selected markers if you choose to test again.

17 markers, grouped by what they reflect. Open a name to see why it is included.
The pituitary signal that tells the thyroid how much hormone to make. It rises when the thyroid is running slow.
The main hormone your thyroid releases, in the unbound form your tissues can take up.
The total amount of cholesterol your blood is carrying, protective and harmful particles counted together.
The particles that carry cholesterol back to the liver for disposal, a marker of how well that return traffic is running.
The cholesterol carried by the particles that can lodge in artery walls.
The fat your blood is transporting between meals and storage, which rises with recent food, alcohol and excess carbohydrate.
The balance between your total cholesterol and the protective fraction, shown for context.
Every cholesterol-carrying particle that can enter an artery wall, in one number.
The circulating store of vitamin D your body draws on, built from sunlight on skin and from what you eat or supplement.
The total B12 in your blood, most of which is bound to a carrier your cells cannot use. It is the standard first-line test and it is a blunt one.
The small fraction of your body's magnesium that circulates in blood. Your kidneys hold this number steady, so it tells you less than people assume.
The waste product your liver makes from used protein and your kidneys clear, so it moves with both protein intake and hydration.
A waste product your muscles make at a steady rate, which your kidneys clear, so it reflects both muscle mass and filtration.
The main protein your liver makes to hold fluid inside blood vessels and carry hormones and minerals around.
All the protein circulating in your blood, albumin plus the antibody and transport proteins.
A protein the liver releases when something is inflamed, measured on the standard assay that reports down to about 5 mg/L.
The adrenal hormone that follows a daily rhythm, highest shortly after waking and lowest late at night.

A broad first look if you want an everyday baseline. For a focused look at iron, explore Vitamin & Mineral Check.
Follow the collection and preparation instructions supplied with your kit. Register your sample and record the collection time before returning it for analysis. If you take medication, ask your clinician about testing; do not stop prescribed medication for a test.
If your sample is insufficient for analysis, we’ll send you a replacement kit at no extra cost.
It gives you a snapshot of the markers included in this panel. One result outside a range does not on its own mean something is medically wrong. Speak to your GP about persistent or concerning symptoms.
Your blood test results are displayed in your Helvy account. You can explore the sample report on this page to see an illustrative example before you order.
Cortisol changes through the day, so record the collection time. This panel does not include iron markers. A broad baseline cannot establish why you feel tired or replace a clinical assessment.
