What We Test | Blood Panels & Blood Draw Locations

Before you read the lists

A marker only matters in context.

A long list of biomarkers is only useful when the results are read alongside your assessment, health history, symptoms, medications, lifestyle and goals.

01

Initial panels are defined

Basics, Foundations and Optimise each begin with an agreed panel so you can understand the starting depth of testing.
02

Follow-up testing is targeted

Where included, your second panel is selected after practitioner review.
03

Results provide direction

Markers contribute to functional health understanding but do not diagnose a medical condition on their own.

Initial panels

What each membership measures.

Choose a membership, then an area of the body. Each list shows the markers in that membership’s first blood and urine panel.

Your essential annual panel

02 Choose your location Use the clinic finder to select a suitable appointment from the available locations across the UK.
03 Attend your blood draw Your samples are collected professionally. The results are then returned securely for your PER practitioner to review.

How to prepare for your test

A trained practitioner in gloves preparing a routine blood draw

Mobile collection

Mobile blood draws, arranged in advance.

We may be able to arrange a mobile blood draw at your home or another suitable location. This carries an additional charge based on your location and collection requirements and must be organised in advance with a member of the PER team.

Speak to our team

Included in your plan

Professional collection is part of your membership.

PER Basics includes one blood draw. PER Foundations, Optimise and Advanced each include two blood draws during the 12-month membership.

Laboratory quality

Our nationwide collection network is provided through Randox Health. Samples are processed by accredited laboratory services operating to recognised UKAS and ISO 15189 quality and competence standards for activities within their accredited scope.
