The 'What's going on with my hormones' Panel
Do you suffer from fibroids, PMS, irregular periods, painful periods, anxiety & moodiness, and endometriosis? Or would you just want to have a complete hormonal functional test?
The DUTCH test offers the most extensive profile of sex and adrenal hormones along with their metabolites. Incorporates a 60-minute consultation and follow-up report with dietary, lifestyle, and supplement suggestions to get you on your way to feeling great again.
A 5-sample dried urine collection test plus saliva sampling can be done in the comfort of your own home.
Complete Thyroid Testing + 30 minute Consultation
The Thyroid Plus is a hormone test that provides a thorough analysis of thyroid hormone metabolism.
It includes central thyroid gland regulation and activity, thyroid production and secretion, peripheral thyroid conversion, and thyroid autoimmunity. This hormone test allows us to pinpoint common imbalances that underlie a broad spectrum of chronic illness
Most standard thyroid panels only look at TSH and T4. This is not enough to tell us whether the thyroid is functioning well or not. In this total thyroid screen, we look at the detailed picture and include the antibodies that are indicated in Hashimoto’s disease:
TSH
Total T4
Free T4
Free T3
Reverse T3
Thyroid Antibodies (TPO & ATG)
As this is a blood test, you will need to organise a phlebotomy appointment to have the bloods taken. Alternatively, we can organise this for you.
The ‘I wonder what my nutrient status is like’ Panel
A unique combination of nutritional tests that provides an analysis of key nutritional biomarkers.
A simple urine and finger prick blood test, all completed at home and sent to the laboratory. The Metabolomix+ panel will give you the perfect snapshot into not only the status of your vitamins and minerals, but also how well you are absorbing and using them. Great for anyone who wants to update their nutrition programme on a regular basis or just get an idea of why they’re not feeling quite right. Or perhaps you’ve adopted a new diet or are thinking of getting pregnant and just want to check everything is top notch.
Gone vegan recently? Feeling more tired than usual? Worried your diet isn’t as good as it might be? Thinking about getting pregnant?
This is a great test to assess nutrient status with optional fatty acid and toxic elements available to add in. A really thorough and easy assessment to let you know exactly what your vitamin and mineral status is.
A first morning void (FMV) urine collection, with optional add-on bloodspot finger stick and buccal swab, the Metabolomix+ nutritional test is a non-invasive, patient-friendly way to assess the functional need for antioxidants, B-vitamins, minerals, digestive support, fatty acids, and amino acids. Insights gained from the Metabolomix+ nutritional test allow us to target nutritional therapies to meet your needs.
The ‘I’d Like a Thorough Check’ Blood Panel
We are very excited to have partnered with Functional DX to bring you the most comprehensive blood chemistry analysis available. The test provides over 75 different blood markers, which we then analyse and place into a comprehensive report to provide an in-depth functional system and nutrient evaluation.
I often ask my clients how much they spend on getting their car serviced every year. And then ask them to compare that with how much them spend on their own health. There’s usually a big difference.
Our signature blood panel is the most affordable and comprehensive blood analysis available today. Unique algorithms assess specific needs, deficiencies and imbalances and place them into easily understandable profiles related to each different organ or potential issue. Each repeated test is added to the original, so you can build up a picture of how you are progressing and improving.
Once we receive the results, we schedule a 60 minute consultation to go through everything and provide you with a detailed plan so you know exactly what you need to work on.
