Can one be very careful? Yes! Required by the Genetic Bank!Only a perfectly secure cord can be stored. "Examination" is expensive. Parents should examine the bank and then undergo the tests. Which ones?
Examine everything and keep what's good ...Have you asked what information the midwife bank is giving the baby doctor? Did you discuss with your parent whether you had bought blood from a cord for bank storage and for what purpose? Has it been found out if you are a practitioner of a letter of interest? Have you asked the bank what qualitative criteria you think are important, or have you financed a sample of foreign currency samples that somehow does not meet international standards? You may find these requests bold, though they may be important. Later, for example, it is not necessarily advantageous for a particular private bank to have a greater need for the customer and the service provided than the international requirements. The price is important, but here it is not true that more expensive service also means reliable quality. You need to make sure that you have the best possible care of your Genetic Bank's bank from the beginning of the invoice to the processing: An important point in processing, for example, is the need to separate white blood cells from blood cells before storage, freezing the complete, undifferentiated cord blood does not correspond to the international one.

This way, it can remain sufficient for loading even in the event of an accident.
These requests may seem somewhat redundant in Hungary, where for the time being there are few, but well-controlled, ways to save a cord. However, it should be borne in mind that privately owned stem cell banks are proliferating worldwide, and the quality of service can be quite large.
Who can give?
Let's see who can be a donor first. Domestic practice in this respect is in line with the guidelines of the European Commission 2004/23 / EC on the donation, collection and testing of human tissues and cells. The conditions are basically the same as for blood or bone marrow donors, but there are also differences. Age and body weight really do not play a role, as women of childbearing age meet the criteria and the amount of blood that can be removed does not depend on the mother's body weight. In this case, it is easier to track the fate of donors, and there is time to detect and detect hidden infections during the blood test.
It is not possible to store the blood of children suffering from an infectious disease (AIDS, hepatitis C), and even if someone is unaware of the infection, it belongs to a vulnerable group. Being tattooed or body pierced for more than 12 months may result in a relationship with an uncontrollable sexual partner.
Requests for anamnesis
- What kind of terrible family sicknesses do they know?
- Do parents suffer from any chronic or autoimmune disease?
- Have you had a family history of cancer or cancer?
- Did the mother have a cancer that could not be cured by local treatment?
- What infectious diseases did the mother have and when?
It is important that pregnancy and childbirth are uncomplicated and cannot be influenced by the blood itself. In the context of future births, it is worth noting that cesarean, twin births are worth taking away from us, and alternative births are not important at home.
The rules for cellular tissue donation apply to both mother and child in the case of the germ line. Therefore, the letter further required a healthy weight of more than 1500 grams in the New Year's Eve.
A physical examination of the mother is also part of the medical history. Different differences are not an absolute reason, it is up to the specialist to decide. The conditions of the letter should also be documented in accordance with Directive 2004/23 / EC of the European Communities Commission and its implementation in Directive 2006/17 / EC. It also provides for tests on donors.
Direction of the color
At least four tests are carried out after the outbreak:
- HIV infection can be detected by the detection of anti-HIV-1,2, an antibody raised against the AIDS virus.
- Hepatitis B infection is detected by detection of HbsAG (hepatitis B virus surface antigen) and Anti HBc (hepatitis B virus core antibody).
- In the case of hepatitis C, the Anti-HCV test is carried out.
- The detection of the syphilitic Treponema pallidum is also important. Early infections may be detected during the examination, the active cause being the exclusive cause, and this is always checked.
All exams must be repeated at birth, with the help of a bloodline letter at the same time as the letter. The results are available within 1-2 weeks. If for any reason you missed the pre-natal blood test, it may take six weeks for the tests to be repeated, which is the amount of time needed to detect latent infections.
Blood cells in quarantineNot only are maternal blood examined, but also samples of the inoculated human cord blood are analyzed for the presence of bacteria and fungi that are in the blood or are in the process of leaf and blood processing. Until the results of all examinations are received, the processed, frozen field cord can only be stored in the temporary storage. Infectious specimens should not be placed in a container for final sterile specimens to be stored.
The HLA-typing test can be performed immediately, following the expulsion of the germ line, or later, from a reference frozen vial. This test is not required for storage, it should only be performed prior to use in case of allogeneic loading.
One more step to securityAfter the genital tract is stored for a long time, and its donors are alive, it may be necessary to perform a repeat sampling and examination after 180 days if there is a need for allogeneic stem cells. Correspondingly, parents with a private label also declare that they will appear one year after birth, and that the baby will be healthy. In a foreign country, for non-private purposes, the bank looks for parents, and they also ask for a pediatric certificate that the baby is healthy. Of course, parents may not be reached. Experience has shown that 20-25% of donors do not come forward, even though this is a special interest, especially in the private storage.
The complete documentation contains the following information:
Among the donor data are, of course, identification (age, birth, mother, and child), age, medical history, physical examination, clinical examination, . The documentation should include the parent's statement of what the blood is used for. (For example, many people do not know that plasma and blood cells that have been separated and wasted can be used for research purposes.)
The collecting organization shall provide the tissue processing and storage institution with the exact name and address, the procedure and conditions of the letter, the name of the specialist responsible for the letter and the date of the letter. It is worth checking all of this.
