How Long Does A DNA Test Take (And Why)?

Exact Answer: 1 to 7 days

The genetic material that you get from your parents is called deoxyribonucleic acid, or DNA. Fatherhood is referred to as paternity. A DNA paternity test determines if a guy is the child’s biological father by analyzing DNA from a cheek swab.

If you require the findings for legal reasons, you must have the test performed in a medical environment. Paternity testing based on DNA is exceedingly accurate. If a guy is not a person’s biological father, a test can reveal 99.9% accuracy.

The length of time it takes to complete a paternity test varies based on the DNA testing firm doing your paternity test. Paternity test results from IDTO DNA paternity testing services are delivered in 1 to 3 business days on average. The majority of DNA testing firms have a response time of 3-5 business days.

IDTO charges an extra fee for same-day paternity test results. Same-day results show that your DNA results will be ready by the end of the business day on the same day that the lab receives your DNA samples.

Establishing paternity is crucial for a variety of reasons. It can assist you in obtaining legal protections to childcare, custody of children, Social Security benefits, and legacy, as well as identifying linkages to genetic diseases that might damage your long-term health.

If you want to confirm or deny legitimacy for official purposes, the test must be performed in a medical environment (a legal DNA paternity test). Alternatively, you can utilize an at-home DNA paternity test kit purchased online or at the pharmacy.

There are two methods for determining paternity that is both equally accurate:

  • Simple blood test: At a medical office, the putative father and kid provide blood samples. The samples are sent to a lab for examination by the faculty.
  • Swabs of the inside of the cheeks for buccal (cheek) cells are taken by both the possible father and the kid. You send the cotton swab applicators to a certain lab. If swabbing is done in a medical context, the samples are sent to a lab.

The lab performs a variety of DNA sequencing assays. These tests seek for genetic similarities between a potential father and his offspring. A match establishes paternity.

Why Does It Take So Long For A DNA Test?

Each individual requires a genetic test that targets a certain gene. Each of us contains a large number of genes in our DNA, and each gene is made up of many different components called exons and introns. It is currently impossible to examine each one of a person’s genes.

As a result, your doctor must establish a clinical diagnosis based on your symptoms and the doctor’s findings, and then ask us to test the genes most likely to be responsible for those results.

The time it takes for lab results to be returned varies. Remember to factor in the time it takes for the sample to arrive at the lab and for the lab to complete its testing. The results may be accessible in two days or longer. For easier access, many DNA testing labs upload findings on a protected website.

The findings of prenatal paternity testing such as CVS and amniocentesis might take several weeks. When the paternity of a child is in doubt, a DNA paternity test might help. Your healthcare practitioner can assist you in determining the most appropriate testing procedure for your circumstances. You should check sure the laboratory is accredited by the Association Of America of Blood Banks whether you utilize an at-home test or go via a medical office.

Conclusion

Molecular genetic testing, while accessible for hundreds of hereditary disorders, is still in its infancy and will likely become a greater part of primary care practice in the future. Physicians must be knowledgeable about the proper use of genetic testing for their patients, as well as current information resources that will enable them to communicate accurate information.

The practitioner must be able to identify his or her role and that of the genetics expert for each patient with an inherited condition by getting familiar with the aspects of a genetic consultation.
