Frequently asked questions

I want to register for a consultation, how can I do that?

First step is to register for an appointment. You can register by phone at 870077333, or if calling from abroad, dial +37068011300. You can also do so via email at Once you have paid the advance payment, your registration will be confirmed. Then, one week before the visit, you will need to undergo blood tests required to calculate the Functional Biology Indexes.

Why do I need to pay an advance payment to confirm the reservation?

Since there is a high demand for appointments, it often happens that some patients register well in advance but then do not show up for the appointment. Such situations are not beneficial for either the specialists or the patients waiting for their turn. Therefore, to encourage our clients to take responsibility when choosing consultation times, we have introduced a non-refundable advance payment to confirm reservations, which is 50% of the consultation fee. When reserving your preferred time slot, you will receive a temporary reservation confirmation email along with a link for advance payment. Failure to make the payment within 48 hours will result in the cancellation of the temporary reservation. In such a case, you will be notified via email. This advance payment for reservation confirmation is included in the total fee. Additionally, we are flexible, and if you are unable to make the payment via Lithuanian banks, we can issue you a pro forma invoice, and you can make the payment via bank transfer within the specified timeframe.

Cancellation and rescheduling policy:

Twice rescheduling the consultation due to tests not performed on time, or rescheduling the consultation less than 7 working days before the consultation, will add a 20% additional work fee to the price of your future consultation.

If we do not receive any response to the SMS sent 14 days before the scheduled consultation date, and you do not respond or return 2 phone calls, we will send you an SMS to the phone number provided during registration, asking whether you intend to perform the blood tests for the consultation. If no response is received within 48 hours, your consultation will be canceled. We will inform you of the cancellation via the email provided during your consultation registration. If the consultation is canceled for this reason, the deposit paid is non-refundable.

If you forget to attend the consultation at the appointed time or notify us of your absence from the consultation less than 7 working days before the consultation date, the deposit paid is non-refundable.

What tests need to be done before the consultation?

To enable the consulting specialist to calculate your biological indices, the following tests must be performed before the consultation:

  1. Glucose in serum/plasma
  2. Potassium
  3. Calcium (total)
  4. ALP (alkaline phosphatase activity)
  5. SF isoenzymes electrophoresis
  6. Creatine kinase activity
  7. LDH (lactate dehydrogenase)
  8. TTH (thyroid stimulating hormone)
  9. FT4 (free thyroxine)
  10. FT3 (free triiodothyronine)
  11. Osteocalcin
  12. CA-19-9
  13. Complete blood count
  14. ENG after 1 hour

It is important to perform all the tests at once, and we recommend doing them at Medicina Practica laboratories.

How to prepare properly for blood tests?
  • Timing: It’s best to have blood tests done before 10 a.m. as hormone and enzyme levels can fluctuate throughout the day.
  • Fasting: Avoid eating or drinking anything (except water) for at least 14 hours before the test. This includes juices, tea, and coffee, as they also count as food. Drinking water before the test is recommended.
  • Dietary restrictions: Limit fatty and fried foods in the days leading up to the test, and avoid alcohol for at least 24 hours before the test.
  • Smoking: Refrain from smoking for at least an hour before the test.
  • Physical activity: Avoid vigorous exercise for at least 48 hours before the test, and try to be well-rested before the test. Avoid stress if possible.
  • Recent illness: If you’ve had the flu, a cold, or any other illness, it’s best to wait until you’ve fully recovered before having blood tests done.
  • Special considerations: Women’s hormonal test results can be influenced by physiological factors related to the menstrual cycle. Therefore, if you are a woman seeking endobiogenics for hormonal disorders (menstrual cycle irregularities, fertility issues, PCOS, etc.), we recommend performing tests on days 19-21 of the cycle. If the cycle is irregular, it’s advised to perform the tests 5-7 days after ovulation.

    If you are taking B-group vitamins, it’s recommended to discontinue their use earlier because biotin (vitamin B7) interacts with certain test methods. Therefore, when taking biotin supplements, we recommend postponing the blood sampling procedure by two days and refraining from using such supplements during this period.

    If you have the flu, a cold, bronchitis, etc., and you’re planning to undergo the necessary tests for endobiogenics, you should recover first and wait 10-14 days after the symptoms disappear before performing the blood tests.

    When is it recommended to undergo tests if you have been or are currently taking antibiotics?

    • If they are locally acting antibiotics, there is no need to postpone the blood sampling procedure (however, you should take the medication only after the blood test!)
    • If they are broad-spectrum antibiotics, the blood sampling procedure should be postponed for at least 2 weeks after completing the antibiotic course.

    If you are undergoing chemotherapy, blood tests should be performed 7-10 days after chemotherapy.

    If you are taking antidepressants, blood tests are performed as usual, and there is no need to discontinue the medication.

    If you are taking thyroid medications (levothyroxine) or other medications for chronic conditions, do not discontinue them.

    If you are taking supplements and vitamins and want to perform additional tests such as iron, vitamin D, or others along with the optimal endo test, do not take supplements and vitamins for at least a week before the blood test.

Where can blood tests necessary for endobiogeny consultations be performed?

You can perform the blood tests required for endobiogeny consultations at any “Medicina Practica” laboratory branch. You can find the contact information for the branches on their website at

I'm using herbal tinctures, but I feel strange. How should I do?

If you’re experiencing doubts or discomfort regarding the herbal tinctures prescribed by the endobiogeny specialist, be sure to consult the endobiogeny specialist. They will assess whether adjustments to your health plan are necessary.

When should you consult an endobiogeny specialist?

Consult an endobiogeny specialist if you suffer from one or more of the listed reasons, or if the treatment or health improvement method applied to you does not yield results:

  • You’re raising a hyperactive, highly sensitive child; your child wets the bed involuntarily; your child has been diagnosed with autism, developmental disorders.
  • Various allergies, asthma, eczema.
  • Migraines, unexplained headaches, Lyme disease, memory problems.
  • Crohn’s disease, thyroid disorders, ulcerative colitis, multiple sclerosis, muscle weakness, celiac disease, arthritis, unexplained pains; digestive disorders (irritable bowel syndrome, stomach diseases, constipation).
  • Women’s menstrual cycle disorders and gynecological diseases, infertility, urinary disorders, prostate diseases.
  • Oncological diseases.
  • Nervous disorders: anxiety, panic attacks, depression, sleep disorders.
  • Cardiovascular diseases, heart rhythm disorders.
  • Inherited diseases.
Questionnaire, why is it important to fill it out?

Filling out the questionnaire is primarily for you; it allows you to remember and clarify your health history from childhood. It may seem strange that the specialist asks questions during the consultation for which the answers are already provided. The purpose of the questionnaire is for individuals to gather all the information and be able to easily clarify it for the specialist. The endobiogeny specialist evaluates the questionnaire data only when together with the patient. People are very different, and everyone’s perception of what constitutes normal health varies, so the specialist clarifies important questions together with you.

What are Functional Biology Indices?

In Endobiogeny, hormones are evaluated as the main regulators of the body. The quantity of hormones in the blood is not assessed, but rather their activity. Hormones are active when they bind to cells, so it’s not just the quantity of the hormone that matters, but also the cell’s ability to receive it, the number of receptors, and the amount of hormone-carrying protein. Knowing the other elements (determined during blood tests) that hormones can influence, mathematical formulas are used to calculate Functional Biology Indices, which indicate hormone activity, balance, and the ratio of one hormone to another. This is the most important aspect of our body’s regulatory process.

After how long should one visit for a follow-up appointment?

It is usually recommended to schedule a follow-up appointment after 4 months from the start of herbal remedy usage. By then, the herbal remedies should have had time to take effect, allowing for an objective assessment of their impact, although it all depends on the issue, illness, and situation. The timing for the next visit to the endobiology specialist is typically communicated during the initial consultation.

Are we collaborating with insurance companies?

We haven’t directly contracted with insurance companies, but you may be able to receive insurance reimbursement if your insurance company covers these services. After your visit, don’t forget the documents you’ll need when applying to your insurance company for reimbursement: invoices confirming the purchase of services and/or goods, and a document showing payment for the services and/or goods purchased: a cash receipt if you paid by bank card.

Where else can I find information about endobiogeny?

The Endobiogeny Institute brought endobiogeny to Lithuania in 2013 when it released the book “Endobiogenika. Individualized Medicine” by Dr. Jean-Claude Lapraz and Marie-Laure de Clermont. However, before that, endobiogeny had already spread worldwide. So, if you want to learn more about the history, spread, and application of endobiogeny, you can visit the website in the “Endobiogenika” section.

Also, in 2023, the Endobiogeny Institute released the first issue of the Endobiogenika journal. So, you will also find valuable information there. You can purchase the journal at our online store of the Endobiogeny Institute website:
