The global hereditary testing market size was valued at USD 6.39 billion in 2022. It is estimated to reach USD 13.65 billion by 2031, growing at a CAGR of 8.8% during the forecast period (2023–2031). Factors such as increasing sales and demand for DNA Test Kits, significantly drives the hereditary testing market demand by 2030
Hereditary genes are passed down to children or are inheritable from parents. Hereditary testing searches a person's genome for particular hereditary variations (variants). Genetic variations may affect a person's chance of contracting a disease in harmful, advantageous, neutral (have no effect), or unknown or ambiguous ways. Hereditary tests, which can also confirm or rule out a suspected genetic disorder, can be used to estimate a person's chance of developing or passing on a genetic disease.
Even when an inherited variation does not bring on cancer, it can occasionally seem to "run in families." However, the presence of a hereditary propensity to acquire cancer may be suggested by certain patterns observed in family members, including the types of cancer that manifest, various non-cancer illnesses, and the ages at which cancer frequently manifests. There are genes linked to many identified inherited illnesses.
Examining if a person has a harmful mutation in one of these genes makes it feasible to assess whether a disorder results from an inherited syndrome. When a family member is known to carry a detrimental mutation, genetic testing is also conducted to see if other family members who have not (yet) developed cancer have inherited the same variant.
DNA testing kit sales have risen due to the steady demand for newborn screening. For instance, in November 2019, the Virginia Department of General Services Division of Consolidated Laboratory Services (DCLS) examined 7,868 newborns for over 31 genetic and metabolic diseases. Nearly 4% of screened babies were diagnosed with a carrier status or a critical disorder. Adopting advanced technologies, such as tandem mass spectrometry, microarrays, proteomics, nanotechnology, and DNA chip technology, has increased the accuracy of test results, thereby enhancing the sales of testing kits for hereditary disorders.
Key players have started advanced tests to maintain market competition and meet high demand. Ariosa Diagnostics, Sequenom, Natera, and Verinata Health (acquired by Illumina) are key players offering Non-invasive Prenatal Testing (NIPT) platforms in the U.S. The novel platforms utilize sequencing technologies, PCR, and proprietary algorithms to analyze Cell-free Fetal DNA (cffDNA) to detect chromosomal aneuploidies, such as Down's syndrome, Edwards' syndrome, and Patau syndrome. Other players, such as Ravgen, Cellular Research, and TrovaGene, have developed NIPT for chromosomal aneuploidies, driving the market growth.
According to National Human Genome Research Institute (NHGRI), genome sequencing costs have been reduced by thousands of dollars over the past two decades, from USD 95,263,072 per genome in 2001 to USD 942 per genome in 2019. This has increased the adoption of genetic sequencing for early diagnosis and treatment of several disorders, including cancer and genetic variations of neurological conditions, cardiac disorders, and cystic fibrosis.
The National Institutes of Health (NIH) developed Genetic Testing Registry (GTR) to enhance access to information on genetic tests. GTR is an online resource launched to centralize comprehensive information regarding genetic tests conducted across the globe. This initiative helped increase access to genetic information for pharmacogenetic tests and germline variations, subsequently increasing understanding of the importance of hereditary testing to prevent clinical disorders and further boost hereditary testing market growth.
Ethical issues concerning the safety of in vitro fertilization and Preimplantation genetic diagnosis (PGD) are expected to hamper the market growth. PGD is morally unacceptable to several people and cultures as it is considered unnatural creation and involves the destruction of human embryos. Application of these tests for sex selection on nonmedical backgrounds is prohibited in several countries, which is expected to restrain application demand and market growth.
Furthermore, high implementation and procurement costs are major restraints for market growth in developing economies. The absence of an appropriate framework for insurance coverage and the accessibility of these tests are other factors expected to restrain growth. Miscoding, overbilling, and subsequent overpayment for genetic tests by insurance providers are further expected to hamper the market growth.
NIPT using cffDNA circulating in maternal blood can help detect common fetal trisomies, such as Down's syndrome, fetal Rhesus D status, and sex chromosome disorders. NGS-enabled clinical applications have witnessed considerable uptake over the past two years. The use of invasive procedures, such as amniocentesis and chorionic villus sampling, has declined over recent years, as non-invasive procedures are steadily being offered routinely at major treatment centers to all women with a high probability of having fetal genetic defects.
NIPTs can be more accurate than current first-trimester screenings, resulting in fewer false positives, consequently reducing the number of invasive amniocenteses performed. Ongoing research can help expand the range of conditions detected through non-invasive means, including duplication/microdeletion syndromes and Mendelian genetic disorders. The use of test results for informed decision-making is expected to drive their adoption rate, creating hereditary testing market growth opportunities over the coming years.

This collaboration further aided in assessing hereditary disorders by integrating clinical and genomic databases.
Inheritance is a factor in 10%–20% of common cancers. Many CLIA-certified laboratories perform tests using blood, saliva, or tumor tissue samples to determine whether an individual carries an inherited mutated gene that can cause cancer. Genetic testing for individuals already diagnosed with cancer can help determine if their cancer was caused due to an inherited mutation. The most common inherited cancer forms include breast, ovarian, prostate, and colorectal cancers. Genetic testing for these cancers accounts for a major share in volume and revenue. In addition, significant factors contributing to the dominance of this segment include increased heritability, high penetration of products, and increased disease prevalence. The hereditary cancer testing segment is further sub-segmented into the following tests: lung cancer, breast cancer, colorectal cancer, cervical cancer, ovarian cancer, melanoma, prostate cancer, stomach/gastric cancer, sarcoma, uterine cancer, pancreatic cancer, and others.
COVID-19 has positive and negative market consequences, as carbon emissions have decreased globally due to the lockout. COVID-19's reduction in emissions is a short-term benefit. Still, when industries and enterprises attempt to recoup some of their financial losses in the first quarter of the year, carbon emissions will rise dramatically. COVID-19 had a negative impact on global recycling efforts. Countries, notably the United States, have halted or decreased recycling programs to focus on collecting additional domestic waste or because services have been disrupted by the virus.
Also, with industries slowly returning to normalcy following the COVID-19 outbreak, this shift in workplace health and safety is expected to increase due to mandatory social distancing and continuous personal care through sanitization to eliminate even the tiniest possibility of COVID-19 spread. COVID-19 has impacted various companies' revenues, and if the lockdown is lifted, companies will turn their attention to operations to make up for their losses.
