1. communication

1. Preparing for Discussions

Before proposing a prenatal paternity test, it is important to first sort out your feelings. If you have concerns or doubts, calmly consider the underlying reasons and be prepared to communicate them openly to your pregnant partner. Here, it is important to be clear about what is troubling you and to speak without blaming your partner.

For example: “I’ve had a lot of concerns recently, and I want to discuss them with you. I hope you understand.”

2. Create a space for open dialogue

Choose a calm place and timing to begin a dialogue with your pregnant partner. Ideally, the environment should be one where you can take the time to discuss the situation when you are not under the stress and busyness of everyday life.

Try not to be emotional, and emphasize that the purpose of the dialogue is to “resolve doubts and discuss how to build a future for the two of you. It is also important to provide reassurance and show that you “want to support each other no matter what the outcome.

3. Communicate feelings openly

In this dialogue, it is important to be candid about your feelings and concerns. However, instead of blaming or accusing the other person, focus solely on how you feel.

E.g., “This has been bothering me for a long time, I’m anxious myself, and I wanted to be honest with you about how I feel.”

4. Seek understanding and empathy

If your pregnant partner is anxious or resistant to the appraisal, it is important to empathize with their feelings and show understanding. Respecting your partner’s opinions and feelings is essential to maintaining trust.

E.g., “How you feel is also very important to me, and I want to think together about how we both can face this issue.”

5. Explain the need for the inspection

It is also important to calmly communicate the reasons why an examination is necessary. Emphasize the need for accurate information, especially when considering the legal process and the child’s future. In doing so, it is important to avoid emotional conflict and to speak rationally.

E.g., “I think this is an important step for us to take to facilitate any future legal proceedings.”

6. Working together to find a solution

It is important that the two people work together in dialogue to determine the next steps. Ideally, even when conducting a paternity test, the partners should be comfortable with the process and agree to proceed.

E.g., “Let’s figure out together what way is best for us.” E.g., “Let’s figure out together what way is best for us.”

2. genetic analysis

If questions remain unanswered, DNA testing can be performed as a scientific method. The following methods are available for DNA testing during pregnancy

DNA testing methods during pregnancy

  1. DNA Prenatal Paternity Testing (NIPPT: Non-Invasive Prenatal Paternity Test)
  • METHODS: Only a buccal mucosa sample from the father and a blood sample from the mother are required. Fetal DNA in the mother’s blood is extracted and compared with the father’s DNA.
  • Advantages: Safe and without risk to the mother or fetus.
  • When: Can be performed after the 6th week of pregnancy. The earlier you know, the more options you have for the results.
  • Accuracy: Can identify or deny paternity with a very high accuracy of 99.99999999999% or better.
    This test is recommended by HIRO CLINIC. It is risk-free and has a high accuracy rate of 99.99999999999% or higher.
  1. Aggressive prenatal paternity testing
  • chorionic villus examination (CVS: Chorionic Villus Sampling)
    • Methods: A portion of the chorioallantoic membrane is harvested and analyzed for DNA.
    • Time of implementation: Can be performed during the 10th-13th week of pregnancy.
    • Risk: There is a risk of miscarriage (approximately 1%).
  • amniotic diagnosis
    • Method: Amniotic fluid is collected and fetal DNA is analyzed.
    • Time of implementation: Can be performed during the 15th-20th week of pregnancy.
    • Risk: There is a risk of miscarriage (approximately 0.5%).

3. DNA testing after birth

If you are not comfortable taking risks during pregnancy, DNA testing can be done after delivery.

  • Methods: DNA samples of the father and child are taken (typically oral cells) and compared.
  • Accuracy: High accuracy in identifying parent-child relationships.
  • Procedure: A professional DNA analysis agency is requested.
  • Whether the father is determined to be the father after the birth or not, some administrative procedures, including family registration, must be taken.

summary

In order to confirm that your partner is the father of your child during your pregnancy, you should first have open communication, and if that does not resolve your doubts, you can consider DNA testing. When conducting an evaluation, it is important to obtain your partner’s consent and to emphasize safety and reliability. It is also advisable to seek professional advice if necessary.
