Prenatal paternity DNA testing (hospitals and clinics)

NIPPT DNA出生前親子鑑定(病院とクリニック)

Paternity testing conducted in hospitals and clinics differ in their characteristics and the services offered.Both institutions perform DNA testing to confirm the parent-child relationship, but there are some differences in terms of equipment, purpose and additional services offered.The following section details the differences between parent-child tests carried out in hospitals and clinics.

1. The size and specialization of the facility

  • Hospital paternity tests:.
  • Size and equipment: hospitals are generally large medical institutions with extensive laboratory equipment and specialists; they are also equipped with the precision testing equipment required for DNA testing, and can handle complex cases and tests during pregnancy (e.g. prenatal testing).
  • Specialist response: larger hospitals often have a team of obstetricians, geneticists and laboratory technicians who are particularly careful with paternity testing and risky tests during pregnancy.
  • Dealing with complex cases: where prenatal paternity tests or invasive tests using amniotic fluid or chorionic villi are required, the hospital has the equipment and medical staff to minimise the risks.
  • Parent-child assessments in clinics:.
  • Size and facilities: clinics are generally smaller and often not as well equipped as hospitals. Even if specimens are collected at the clinic, the actual DNA testing itself is usually outsourced to a specialist external organization.
  • Scope of expertise: clinic doctors are often specialists in obstetrics and gynaecology or internal medicine, but may not have a specialist on staff who specialises in DNA testing.In many cases, they deal specifically with general paternity testing (confirming the parent-child relationship after birth).
  • Dealing with simple cases: clinics are well equipped to deal with common paternity tests (using saliva and oral cells), but complex cases and risky tests are often referred to better equipped hospitals.

2. Types of tests and risk management

  • Hospital paternity tests:.
  • Paternity testing during pregnancy: hospitals can provide paternity testing during pregnancy (prenatal paternity testing).Options include, for example, amniotic fluid or chorionic villi samples to check the fetus’ DNA, or non-invasive methods using maternal blood (NIPP).As these tests involve risks, hospitals will have appropriate equipment and specialist risk management.
  • Risk response: there is a risk of complications and miscarriage with invasive tests, but the hospital has emergency services available and is prepared to deal quickly with any problems during the test.
  • Parent-child assessments in clinics:.
  • Postnatal paternity testing: postnatal paternity testing (DNA testing using saliva and oral cells) is the main procedure used in clinics.This test is simple, risk-free and non-invasive.
  • Low-risk tests: invasive tests (amniotic fluid or chorionic villus sampling) are generally not performed in clinics.If the risk is high or special tests are required, the woman may be referred to a hospital with better facilities.

3. The type of service provided

  • Hospital paternity tests:.
  • Comprehensive medical services: hospitals provide comprehensive medical services beyond paternity testing.For example, genetic counselling, antenatal care and risk management are provided at the same time, so that total support is available.
  • Legal support: when paternity tests are used legally (e.g. in court or inheritance matters), the results of the tests carried out at the hospital are reliable and legally more likely to be accepted as evidence.
  • Parent-child assessments in clinics:.
  • Simplified testing: clinics offer a simplified paternity testing service. The process involves collecting specimens and sending them to an external DNA laboratory for results. The clinic acts as a contact point for the collection.
  • Testing for personal purposes: some clinics may offer a simple paternity testing service for patients who wish to have an assessment for personal purposes (e.g. to verify parent-child relationships) rather than for legal procedures.

4. Differences in costs and procedures

  • Hospital paternity tests:.
  • Tendency for higher costs: paternity testing in hospitals tends to be more expensive, especially for prenatal paternity tests and invasive tests, due to the equipment and specialists involved. Notarization of results and other procedures may also be required if the results are to be used as legally valid evidence.
  • Long-term support: after the appraisal results are available, you will receive long-term support, including genetic counselling and follow-up treatment.
  • Parent-child assessments in clinics:.
  • Relatively low cost: paternity appraisals in clinics are relatively inexpensive because they generally use non-invasive and simple methods. Even when the appraisal is outsourced to an external agency, only basic procedures are required, thus saving time and money.
  • Simple procedure: for personal use purposes, the procedure is very simple and results can be obtained in a short time if no legal proceedings are required.

5. Reliability as legal evidence.

  • Hospital paternity tests:.
  • Highly legally valid results: the results of a paternity test carried out in a hospital are highly reliable, even when used as legal evidence. A certificate may be issued for use in court or official proceedings.
  • Parent-child assessments in clinics:.
  • Legal use may be limited: paternity tests carried out in clinics are often intended for personal confirmation and therefore may not be accepted as reliable when used as legal evidence.It is important to check with the clinic beforehand if it is to be used as legal evidence.

Summary

  • Hospital-based paternity testing can provide comprehensive medical support and legally valid results, with facilities and specialists available for paternity testing, particularly during pregnancy and for high-risk tests. Although more expensive, hospitals are the right choice for legal evidence or when dealing with complex cases.
  • Paternity testing in the clinic provides a simple and inexpensive paternity testing service, mainly for non-invasive post-natal

Supports assaultive appraisals. It is suitable for appraisals for personal confirmation purposes, but may refer to hospital if legal proceedings or high-risk tests are required.

It is important to choose between hospitals and clinics according to your situation and objectives.
