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 samle collection in the comfort of your own home.

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

For those in Europe and not UK, there is an additional fees (25-55£) for mailing, which will be indicated in your test kit.

DUTCH hormone test


Note 1: this test should be performed between days 19 and 22 of your menstrual cycle, though if this does not apply i.e. amenorrhea, anovulation, perimenopause (irregular pattern) or menopause, the test can be done on any day.


Supplementation: stop supplementation 2 days before and during test.

Liquid consumption: do NOT drink any alcohol, caffeine or large fluid intake after lunch. Try not to drink fluids for two hours before collecting, or keep under 32 oz, if possible. 

Foods: Avoid avocado, bananas and fava beans for 48 hours before collecting.  


Collection days and times:


Sample 1 - Dinnertime 5pm  . 

Sample 2 - Bedtime Approximate 10pm.

Extra Overnight Sample - ONLY IF NECESSARY - Collect at your first waking sleep disturbance with urination* *If you wake and urinate a second time during the night, do NOT collect. 


Wake/Rising - take sample within 10 minutes; Do not lay awake in bed before sample 

Sample 3 - take 2-hrs After Waking (Tip: set a timer on your phone).



- If you happen to miss a collection, simply collect the sample as instructed the following day, as all samples do not need to be collected in one 24-hour period.

- Send back as soon as possible, maximum 7 days after collecting as validity is usually 10 days.   

- If you are unable to urinate at the specific time, I suggest  drinking some fluids and to go as soon as you are able

Thyroid profiling:

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

Toxicity - Environmental Pollutants

The GPL-TOX screens for 172 different environmental pollutants using 18 different metabolites from a single urine sample including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, pyrethroid, insecticides, acrylamide, perchlorate, diphenyl phosphate, ethylene oxide, acrylonitrile and more. The profile also includes Tiglylglycine (TG), a marker for mitochondrial disorders resulting from mutations of mitochondrial DNA. These mutations can be caused by exposure to toxic chemicals, infections, inflammation and nutritional deficiencies. The GPL-TOX uses advanced mass spectrometry (MS/MS) which is necessary to detect lower levels of certain genetic, mitochondrial and toxic chemical markers that conventional spectrometry often miss. It pairs perfectly with other Great Plains Laboratory tests to assess for exposure to common environmental toxins. These include the Organic Acids Test (OAT) and the Glyphosate Test. Exposure to environmental pollutants has been linked to many chronic diseases.
