Protect the systems that keep you alive and performing.
We test liver, kidney, prostate, and immune markers to detect early dysfunction and support healthy ageing from the inside out.
Blood Biomarkers:
- Alanine Aminotransferase (ALT): Liver function.
- Creatinine (with eGFR): Kidney function.

How do I prepare for my blood test?
- Arrange for your sample to be taken between 6am and 10am.
- Take this test when any symptoms of short-term illness have settled.
- Take this test two to five days after the start of your period, ideally on day three. It can be taken any time if you do not have periods.
- Avoid heavy exercise for 48 hours beforehand.
- Avoid fatty foods for eight hours before your test.
- Fasting is not mandatory, but if your apolipoprotein results are raised, you may be advised to confirm this with a fasting sample.
- If you are fasting for the test, do not eat or drink anything other than water for 12 hours beforehand and take any medication as you would normally.
- Stay well hydrated before your test.
- Take your sample at least 24 hours after any vitamin or mineral supplements.
- Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.
- Do not take vitamin B12 for two weeks prior to this test. If your B12 is prescribed ask your doctor whether to stop.
- Hormonal contraception can affect the results of this test. Taking a break from this and waiting for your periods to restart before your blood test will give more accurate results.
- If you take thyroxine, you can take your medication as usual, either before or after your blood test. However, if you take desiccated thyroid extract (DTE) or liothyronine, it's best to take it after you've collected your sample.
- Please let us know in your supporting information if you take amiodarone or lithium as these can affect your thyroid function results.
