Demand for At-Home DNA Tests

There are several reasons behind the global market growth of at-home DNA testing kits. Experts have cited the following explanations:2

  • The increasing number of people who are learning about these tests
  • Growing demand for personalized DNA services
  • Rising incidences of genetic diseases around the world
  • More people can afford these tests

Due to the large number of DNA test providers selling at low costs, the U.S. market is expected to continue dominating North America from 2022 to 2032.2

Many international companies are also expected to enter China to sell affordable genetic testing kits. This might help drive the local market.2

Factors That Affect The Likelihood of Taking A DNA Test

Researchers found that certain situations increased a person’s likelihood of taking a DNA test.13The 2018 survey also reveals whether they were more likely to take a medical genetic test or an at-home kit.13

DNA Statistics (2024): Latest Facts on Genetic Testing 22

In general, American adults were more likely to take a medical DNA test than an at-home genetic test if:13

  • It was advised by a doctor (31% vs. 16%)
  • They have a family history of a particular cancer (23% vs. 18%)
  • They have a general fear of cancer (20% vs. 18%)

However, American adults tended to prefer at-home DNA tests over medical genetic testing in the following situations:13

  • A friend or a family member has taken a DNA test (17% vs. 9%)
  • If they read about DNA testing in the media (14% vs. 7%)
  • A public figure they follow has taken a genetic test (5% vs. 3%)

Common Concerns on DNA Testing

In 2018, 1,109 American adults took a poll on genetic testing. Many people who took the poll were (and are) concerned with the privacy of their data.14

According to a survey conducted in 2022, privacy concerns are common in people who have taken the test and those who haven’t. This affects their decision to take a DNA test.10

The 2018 poll also revealed that while up to 52% were interested in taking a genetic test, many Americans are not fully convinced of the reliability of DNA tests.14

Sharing of Genetic Data

  • 4 out of 10 Americans think that an at-home DNA kit is reliable for identifying ethnic backgrounds, diagnosing diseases, or revealing carrier status for a genetic disorder they might pass on to future children.14

American Trust in Sharing DNA Data with Law Enforcers

Most Americans (48%) think it’s acceptable to share a person’s DNA profile with law enforcement. However, a significant number (33%) think it’s unacceptable.15

DNA Statistics (2024): Latest Facts on Genetic Testing 25

Differences in opinion were observed depending on the age group and sex of the people who took the survey. For example:15

  • A higher percentage of American women find it acceptable to share DNA information than American men (53% vs. 43%).
  • American men are divided about the sharing of DNA data with law enforcers. Forty-three percent find it acceptable, while 40% think it’s not.
  • American adults aged 18 to 49 are likelier to think that sharing genetic information with law enforcers is unacceptable compared to those aged 50 and above (36% vs. 29%).
  • Majority of Americans aged 50+ believe that sharing genetic data with law enforcement is acceptable (56%). Only 29% of people from this age group find it unacceptable.

Opinions on DNA Test Results

People who have taken a DNA test usually have varying opinions on their test results. However, most find them helpful.14

  • Among those who have taken a DNA test, 85% find their results to be useful.14
  • Sixty percent would want to be informed if they have genetic variants linked to incurable diseases. Thirty-nine percent say they don’t want to know if they have such genes.14

Regardless of their preference around test results, most people (82%) would inform their siblings and children if they have a hereditary condition.14

DNA Statistics (2024): Latest Facts on Genetic Testing 26

Young American adults under 40 are usually more interested in finding their predisposition for a genetic disease. Up to 71% will want to know if they are at risk of developing a health condition.14

Older Americans who are aged 40 and over are divided. Fifty-three percent want to determine if they are genetically predisposed to a disease. Forty-six percent would rather not know.14
