“With larger panels like this one, a venous draw gives the lab more sample to work with — which means more consistent results across all your biomarkers. It’s the same method used in NHS clinics, and a nurse comes to you at home.”

Internal Health Check

£109

Check your liver, kidneys and key organs. 28 markers for a clear picture of your internal health.

What this test is for: This panel looks at your heart & cholesterol, blood sugar & metabolic, liver and kidney, plus 3 more areas — to help you understand your health and how you're ageing. For general wellbeing and understanding how you’re ageing — not a diagnosis.

Clear organ picture

Liver, kidney and electrolytes all in one focused panel put my mind at rest about my internal organs. The ALT, AST and eGFR results came with helpful context on what's normal.

Reassuring liver and kidney check

I wanted a proper look at how my organs were performing and this delivered 28 markers covering exactly that. The nurse visit was professional and the results were easy to follow.

Fiona D.12 Apr 2026

Focused and useful

A solid panel if you specifically want liver and kidney function rather than a broad wellness test. The bilirubin and creatinine results were clearly explained.

How to prepare for your test

Before your test

  • Take your sample first thing in the morning, before breakfast — this gives the most accurate readings for cholesterol, glucose, and hormones
  • Water is fine beforehand — stay well hydrated the day before and on the morning of your test
  • Ideally collect before 10 am, when hormone levels are at their baseline
  • Avoid alcohol for at least 24 hours before your test
  • If you take regular medication, take it as normal unless told otherwise by your GP
  • Avoid intense exercise the evening before — it can temporarily affect some markers

If you’re using the finger-prick home kit

  • Warm your hands under warm water for 2–3 minutes before collecting
  • Use the side of your ring or middle finger (not the tip) for the best blood flow
  • Let gravity help — keep your hand below your heart while collecting
  • Gently massage your finger towards the tip; don’t squeeze hard
  • Fill the tube to the marked line — an underfilled sample may need repeating

When to post your sample: Post your sample on the same day you collect it, Monday to Wednesday. Royal Mail typically delivers next day, so your sample arrives at the lab fresh. Avoid posting on Thursdays, Fridays, or before a bank holiday to prevent your sample sitting in transit over the weekend.

Watch video: how to collect your sample

If you’ve booked a nurse visit

  • A qualified nurse will come to your home at your chosen time
  • The venous draw takes around 5 minutes — quick and straightforward
  • Wear a short-sleeved top or loose sleeves for easy access
  • After the nurse collects your sample, simply package it using the prepaid envelope included in your kit and drop it at a postbox the same day
  • Venous samples provide the lab with a larger, higher-quality sample for the most reliable results

Posting after a nurse visit: The same posting rules apply — send your sample the same day, Monday to Wednesday, to ensure it reaches the lab promptly.

After your test

  • Results are typically ready within 2 working days
  • You’ll receive a notification when your results are available in your dashboard
  • Each marker comes with a personalised explanation of what it means for you
  • If you use a health wearable (Apple Watch, Oura, Whoop, Garmin, etc.), connect it in your account after placing your order — we’ll combine your blood data with daily metrics like sleep, activity, and heart rate for deeper, more personalised insights
