Functional Testing

After initial consultation, if necessary and agreed upon, I can recommend testing from the following laboratories to gather specific clinical data and monitor patent progress.

To proceed with the tests, full name, home address, email address, phone number and date of birth (DOB) are required for me to register you as my patient. The tests are then sent to your address, where you can perform the sample collection in the comfort of your own home.

You can return the sample(s) via UPS/DHL mailing services, Royal Mail as indicated on instructions in your test kit, or in person directly to the lab.

Complete instructions can be found inside your test kit and summarised to your right

For shipping to and from Europe, there is an additional fee (between 25-55£) for mailing, which will be indicated on your paperwork in your test kit.

Thyroid Monitor and Vitamin Home Test:

The Thyroid Profile analyses serum levels of TSH, Free T3, Free T4, Total T4, Total T3, Thyroid Peroxidase Antibodies (TPO), Thyroglobulin Antibodies (TGA), Reverse T3 (rT3), T3 Uptake and TSH Receptor Antibodies (TRAb), CRP, vitamin D3, and vitamin B12, excellent to couple with the Adrenal Corticoid test profile.

Notes: The addition of TRAB to the Thyroid Complete Profile offers the practitioner a way of distinguishing between Graves Disease and Hashimoto's.

1. Wash hands with warm water, dry and massage hands to increase blood flow.

2. Open Microtainer (stand upright and secure).
