The analyses did not reveal autism in the child, we are happy
I liked everything, I was a little scared when my son was taken to the mrt, but thank you everything went well, the analyses did not reveal autism in the child, we are happy, the cause of zprr is not known. Speech therapy and vitamins are prescribed. Further time will show. The clinic is clean and comfortable. However, the price for pulling a tooth was significantly high compared to other clinics because at that moment I had a toothache. Significantly high is 10 times more expensive, but in principle, the clinic is large, clean, and the devices are new.

Everything is super ❤️❤️❤️🙌 🕊️ Hugs to everyone, and if we go anywhere, it will be only to you ❤️
Initially I would like to thank Julia, the curator of Bukimed. For accompaniment, for support on the phone, for finding the clinic and doctor, for the hotel and everything else. Yulia you are great ❤️🕊️Когда I will contact Bukimed next time, I will ask for you. Thank you for the transfer. Thank you for the hotel. At the reception everyone speaks perfect English. That's great. In the kitchen the cooks are super ❤️ my daughter liked everything very much. The food is super ❤️ Hello to Tempo Chaglayan Hotel, from Anastasia and Eva, we were there from 14.04.24 to 20 . 04.24 to translators Nadezhda and Madina a big hello and a heart ❤️🕊️🕊️. Liv Clinic is very beautiful ❤️ Professor Cardiologist Batur Genenc Kanar Professional . Very grateful for competence and for honesty in many points . Thank you for the fact that the doctor said to wait with the operation for my daughter, on the heart, that it is necessary to wait a little more and understand the drugs. He didn't do the operation for the sake of money as soon as we arrived. He didn't prescribe unnecessary tests. The doctor said that these analyses are not necessary. ( One genetic test was enough) . I am thankful that Professor Batur Genench Kanar, having prescribed serious pills for my daughter, left his watsap number and said that he is always in touch and at any moment you can call and write directly to the doctor. Which is very convenient for me. We are from another country and it would be expensive to fly to Istanbul for every question. At the moment we are doing everything as the doctor said. We give all the prescriptions to the child. In a month the doctor said to write him an ECG. And there they will decide how to proceed. I am very grateful to everyone who met us on this trip. Everything is super ❤️❤️❤️🙌 🕊️ Hugs to everyone, and if we go anywhere, it will be only to you ❤️.
