Q. Can I direct my client to order directly from you?

  • No. We only deal directly with health care professionals, all orders are placed through them.
  • We do have an option where your client can pay directly. This is dealt with at the concluding part of the ordering process. Please note, that if you choose this option, your patient will be paying the practitioner price.
  • If the option for CLIENT TO PAY is chosen, then a unique URL will be generated. This will be sent to the client, but we recommend that you make a copy of the URL and send that to your client. This enables you to track that they are going to carry out the test and make payment.
  • Once you have placed the order, you will receive an invoice and a copy of the requisition form. Clients will be sent a copy of the requisition form, but we strongly urge you to also send them a copy, as it is possible for emails to be sent to spam at the client end.
  • If the client pays (see above) they will receive a receipt of payment and a requisition form.

Q. What information do I need to provide?

  • Client’s full name – this must be the same name to be used on the blood tube
  • Client’s date of birth
  • Client’s gender
  • Client’s address
  • Client’s email

Q. How do I get a kit?

Option 1:

  • When supplying the client’s details, you will be asked if your client needs a kit to be sent to them.
  • Answer yes, then a kit will be sent by first class post to the provided address. If you answer no to a kit, it will not be sent.
  • If the address provided is incorrect, then we will require you to purchase another kit or reclaim the kit sent to the wrong address. Replacement kits are charged at £25.00
  • Please note that there is a charge for lost kits.

Option 2:

  • If your client is going to a clinic that holds a stock of our kits, please do not order a kit to be sent. Otherwise, we will raise a charge for the extra kit or expect the extra kit to be returned to us unopened.
  • Please note that rectifying any of the above issues will hold up the blood analysis process.

Q. I have clients outside of the UK, can I order FDX test reports for them?

  • Yes, we can help with arranging kits to be sent abroad and facilitate the return of the kits. However, some countries do not allow the transport of biological specimens, if you have any concerns please contact info@functionaldx.com.
  • Sending kits outside the UK will incur an extra shipping and admin fee. Please note that international courier fees vary from country to country, so this is an on-request service. For more information, please contact logistics@functionaldx.com.
  • The same FunctionalDX rules still apply to overseas clients as if they were in the UK.
  • If your clients can facilitate their own test abroad, we can take the data and process this under the order of our own report section. We require a PDF of the test results in English. If the PDF needs translating, this will incur an additional fee.

Q. What are the suggested retail prices for clients?

  • FDX is a practitioner to practitioner only site and as such we do not have Retail Prices.
  • We have suggested guideline prices in the test section of the site.
  • We believe the choice of what clients pay is entirely down to the professional and we do not interfere with your business model.

Q. My client/s are on medications, how will that affect the report? Should I stop these?

Do not stop medications. These are the province of their medical health care professional and any discontinuance should only be done with their permission and under their instruction.

  • The results will indicate if the medication is working at the appropriate levels which would not be apparent if the medications are stopped.
  • Women who have been on contraception: As the effects of these devices and pills take time to be eliminated for the body when discontinued, we recommend testing 6 weeks after the date of discontinuance.

Q. When is the best time of day to be tested?

  • As the test is fasting and 12 hours will have elapsed it is sensible to see a test carried out early morning.
  • In the case of testing with reporting on hormones; due to the circadian rhythms involved we recommend early morning fasting tests i.e. 9 to 10 am if possible.

Q. I want to assess female hormone levels, when should my client be tested?

  • For menstruating females, we recommend that testing be carried out on day 21 of their cycle, if possible.

Q. I want to assess female fertility levels, when should my client be tested?

  • For female fertility panels, test on day 3 of their cycle and a further assessment on day 21 of their cycle

Q. I want to test children or a client under 18, can I do this?

  • Yes, this is possible, if this is required please speak to the team via info@functionaldx.com to discuss the requirements and results pertaining to minors

Q. How do I choose what panel is suitable for my client?

  • We have the most extensive selection of substantial panels in Europe, covering requirements for males and females, conditions, and lifestyle needs.
  • We recognise that it may be necessary to start small, so we have an introductory panel which can be upgraded to some of the larger panels within 30 days of date of order, or after results have been generated if required. We also offer a similar upgrade scheme with thyroid panels.
  • For more information, please see the published information on our site and practitioner pages.
  • Still unsure which panel is right for you? We have a dedicated support team available to help you decide if required. Contact info@functionaldx.com

  1. Your client can choose from a range of blood draw location here or from the blood draw locator section on the site.
  2. Unless stated otherwise we recommend the protocol for an FDX blood draw as follows
    • If ordering a full FDX panel, then we recommend a fasting test (12 hours)
    • Water must be drunk, or results will be skewed. Fasting does NOT mean no water
    • No supplements unless otherwise ordered by you or the clients medical professional for 24 to 48 hours beforehand.
    • Medications should not be stopped unless health care provider instructions say otherwise.
    • Full client and phlebotomist instructions can be found here. Copies are included with the kit please ensure they are followed by both parties.
      • FDX does not take responsibility for any errors or misconceptions
    • Blood draw is through Venipuncture through qualified phlebotomists or venipuncturist.
    • The cost of the draw and spin is payable directly to the draw centre and is not included in the cost of the FDX report and panel.
    • Blood should be drawn, and tubes filled in a specific order (see the phlebotomy instructions).
    • Blood volume drawn is around 40mls
    • Blood MUST be centrifuged (see instructions), for more information on centrifuging see here
    • On completion of the test it is essential for the requisition form to be returned in the completed blood draw kit. Failure to return this will cause £25 admin fee to be levied.
    • If the blood draw centre has no prior arrangements in place with FunctionalDX for courier collection then the completed kit must be closed and labelled as per the instruction included (also see here) and taken to a post office for return using the enclosed label. 
    • It is the responsibility of the returning party to ensure the opening hours and facilities of their post office.

      • FDX takes no responsibility for courier delays or issues and any consequential loss.

    • Should the client wish to be covered against such instances that cause the draw to be invalidated then we advise they purchase a special delivery by 9am or by 12pm delivery the next day and they can ensure they are covered for any losses directly with the post office.

Q. What if I can’t get to the blood draw centre can I get a blood draw at home or in my office?

  • Yes, if you arrange for a mobile phlebotomist to carry this out. The blood draw finder on the web site here will give some mobile operators but the same principles and terms apply as with the clinic as stated above.
  • FunctionalDX insists that all samples are returned are from FunctionalDX kits. Without written permission we will not process any samples that arrive in any other box.

Q. When am I able to draw my blood?

  • Monday through Thursday only. Sending blood on a Friday will invalidate the sample and the process will need repeating a new kit will need to be purchased.
  • Bloods must be returned to FunctionalDX the same day of draw.
  • Restrictions will apply where the last working day of the week is a national holiday in the UK or Ireland.

Q. Finger prick testing and FunctionalDX

  • FunctionalDX tests and reports on large numbers of biomarkers – from 65 to over 120 markers. The volume of blood needed for this cannot be collected by fingerstick testing.
  • Sample needs to be stable so centrifugation of samples is essential in all cases unless otherwise confirmed by us in writing, as some samples are sensitive to degradation, this can’t be done with finger prick collection.
  • Venepuncture is the drawing of blood through the veins is still the gold standard for reliability and accuracy and is our first choice.
  • For very small assessment samples i.e. follow-ons FDX can offer a finger prick test kit.

Q. How do we return samples?

  • If your collection centre has an arrangement with FunctionalDX for a courier service, then leave the bloods and requisition form with them and they will deal with these.
  • If no arrangement exists, then all samples need to be returned to FunctionalDX via Royal Mail special delivery service per the enclosed label. As stated above FunctionalDX accepts no responsibility for sample stability, late delays or any other circumstance that causes the bloods on arrival at the lab to be classed as void.
  • Should clients wish to ensure they are covered for consequential loss for the Royal Mail or designated courier / carrier service they are advised to purchase their own special delivery by 12 or 9am next day by purchasing insurance and consequential loss protection.
  • In all cases samples must be returned on the day they are drawn.
