How it works

What should I expect during a blood draw?
  • A trained phlebotomist will guide you through the process.
  • A tourniquet is placed on your upper arm, the site is cleaned, and a fine needle is used to collect blood into one or more tubes.
  • Results are usually ready in about eight days.
  • Most people feel only a quick pinch.
  • The needle is removed, gentle pressure is applied, and a bandage is placed.
How do I prepare for a blood draw?

Fast for 10 hours beforehand — water is fine and encouraged. Keep taking any prescribed medication unless your clinician has told you otherwise, and skip heavy exercise the evening before so your markers read at baseline.

What should I do after my blood draw?

Leave the bandage on for a couple of hours, drink a glass of water, and eat something within the hour. Light-headedness passes quickly for most people; if it lingers, sit down until it clears and message your care team in the app.

How do I book a blood draw with Emmer?

Pick a slot from your dashboard after your intake form is complete. You can choose a partner draw site or an at-home visit, and you'll get a reminder two days ahead with your fasting window already worked out.

Where can I take my blood test?

We work with 2,140 accredited draw sites across the country, plus mobile phlebotomists in 38 metro areas. Enter your postcode during booking and the four closest options are shown first.

Our testing

Does Emmer replace my primary care provider?

No. We're built to sit alongside your regular practice, not in place of it. Your clinician can request a copy of every panel, and we'll flag anything that needs an in-person visit rather than trying to manage it ourselves.

How fast are blood test results and how do I read them?

Most panels land in your dashboard within eight days of the draw. Every marker is plotted against your own history and an age-matched range, with a short written read-out from a clinician on anything sitting outside it.

Does Emmer accept health insurance?

Membership is paid directly rather than billed to an insurer, which keeps the panel selection independent of what a plan happens to cover. We issue an itemised receipt you can submit to an HSA or FSA administrator.

What if I want more than one blood test per year?

Members can add a follow-up panel at any point for £128, and most people who are tracking a change run one at the three-month mark. Anything your clinician orders as a recheck is included at no extra cost.

Which biomarkers does the standard panel cover?

The baseline panel reads 74 markers across metabolic health, cardiovascular risk, liver and kidney function, thyroid, inflammation, and nutrient status. Hormone and heavy-metal add-ons can be attached to the same draw.
