Summary of this article
DNA prenatal paternity testing is gaining attention as a means of confirming parent-child relationships during pregnancy, thanks to advances in medical technology. The test is designed to confirm the parent-child relationship between the fetus and the father, and is increasingly non-invasive and more accurate than traditional methods. However, the psychological impact of the results can be immense and therefore appropriate support is important. This article provides basic information on DNA prenatal parentage testing, the psychological impact of the test results and how to provide appropriate support in response.
Basic information on DNA prenatal parentage testing
1. what is DNA prenatal paternity testing?
DNA prenatal paternity tests are used to confirm the parent-child relationship between the fetus and the father during pregnancy. The following methods are mainly used
Maternal blood test（Non-Invasive Prenatal Paternity Test, NIPPT）
Maternal blood testing is a method of extracting fetal DNA from the mother’s blood and comparing it with the father’s DNA. This test has the following advantages
- Non-invasive: only a blood sample is taken, with little risk to the fetus or mother.
- High accuracy: state-of-the-art technology allows parent-child relationships to be verified with a very high degree of accuracy.
- Early implementation: can be performed from the sixth week of pregnancy, giving relatively early results.
Chorionic examination (Chorionic Villus Sampling, CVS）
Chorionic villus testing is a method whereby chorionic tissue is collected in early pregnancy and compared with the DNA of the fetus. Features of this method include:
- Invasive: chorionic villus testing is performed between the 6th and 13th week of pregnancy and involves taking a tissue sample using a needle. This involves risks and there is a slight chance of miscarriage.
- Early results: results can be obtained relatively quickly as they can be performed early in pregnancy.
- High accuracy: DNA is collected directly from the trophoblastic tissue, resulting in highly accurate results.
2. inspection process
The process for undergoing an inspection is as follows:
- Counselling: seek counselling at a healthcare setting to understand the purpose and methods of the test. The doctor or counsellor will explain the benefits and risks of the test.
- Sample collection: samples are taken from pregnant women. In the case of maternal blood tests, blood is collected; in the case of trophoblastic tests, trophoblastic tissue is collected.
- Analysis: DNA analysis is carried out on the samples collected. Parent-child relationships are analyzed using advanced techniques.
- Result notification: test results are notified after a few weeks.Results are usually provided in the form of an explanation from the doctor.
Psychological consequences of the outcome.
1. Positive result (if parent-child relationship is confirmed)
Many people will feel a sense of relief and joy if a positive result is found. However, the following psychological effects should also be considered
Increased responsibility
Once the parent-child relationship is confirmed, the father may feel a stronger sense of responsibility as a father. This sense of responsibility may be felt as pressure to raise children and play a role in the home.
Changes in relationships
Test results may affect relationships within the household. For example, different opinions and expectations of the test results may affect the partnership. It is important to work with partners and keep an open line of communication open.
2. Negative results (where parent-child relationship not confirmed)
Negative results can have a significant psychological impact. The following effects are possible:
Surprise and confusion
When confirmation of the parent-child relationship has a disappointing outcome, it can be surprising and confusing. Such an outcome can cause deep emotional damage because it goes against one’s expectations and trust.
Interpersonal problems.
Negative results can cause tension in the relationship with the partner. The relationship may deteriorate if they are not satisfied with the results or if others are made aware of the results. In particular, confirmation of the parent-child relationship can affect trust within the family.
Social impact.
There may be social pressure and blame as the consequences regarding the parent-child relationship become known to those around them. In these situations, support is needed to cope with external pressures.
Methods of psychological support for results.
1. The importance of counselling
If the test results are unexpected, it is important to seek professional counselling. Counselling can help to sort out feelings and establish coping strategies.
Individual counseling
Individual counselling sessions are provided by a professional counsellor who can offer support in sorting out emotions and problem-solving. They can help individuals understand the impact of test results on them and learn skills to cope with them.
Couples Counselling
Couple counselling can be helpful when outcomes affect the partnership. Couple counselling allows couples and partners to work together to solve problems and learn approaches to improving their relationship.
2. Use of support groups
Joining a support group with others who have similar experiences can provide empathy and share real-life stories and advice. Support groups are a valuable resource for reducing feelings of isolation and anxiety.
Online forums and groups
Participating in online support forums and groups can provide extensive support beyond geographical constraints. You can gain emotional support by sharing information and experiences with others.
Local support groups
Local support groups offer face-to-face support through practical meetings and events. You can interact with local professionals and other parents and receive practical advice.
3. Information gathering and education
It is also important to gather accurate information about and gain a better understanding of DNA prenatal paternity testing. Explanations from health care providers and experts can help you to better understand the purpose and results of the test and help you to deal with them calmly.
Explanation from health care providers.
An explanation from your health care provider will help you understand the testing process and how to interpret the results. Based on expert advice, you can find ways to cope with the results.
Use of specialist books and materials
Specialist books and resources can help you gain an in-depth understanding of the background and techniques of testing. Knowledge from reliable sources can help prepare you for the results.
Summary
DNA prenatal paternity testing is an important method of confirming parent-child relationships during pregnancy, and advances in science and technology are making it more accurate and safe. However, the psychological impact of the test results can be significant and appropriate support is needed. Counselling and support groups can be used and adequate information can be gathered to help people cope with the results appropriately. Using groups and understanding accurate information is essential. With these supports, it is hoped that women will feel more secure during the pregnancy period and be able to respond positively to the outcome.
