Genetic Testing Market Overview:
The global genetic testing market is anticipated to expand at a compound annual growth rate (CAGR) of approximately 10% during the forecast period. Market growth is driven by the rising prevalence of genetic disorders, increasing emphasis on early and preventive healthcare, growing demand for direct-to-consumer (DTC) genetic tests, and the expanding use of genetic testing in oncology.

Genetic testing is a medical diagnostic procedure used to identify changes or abnormalities in genes, chromosomes, or proteins. Test results help confirm or rule out suspected genetic conditions and support the assessment of an individual’s risk of developing or passing on inherited disorders. Genetic testing encompasses several key categories:
- Diagnostic Testing: Used to confirm genetic conditions in symptomatic individuals, such as cystic fibrosis or Huntington’s disease.
- Presymptomatic and Predictive Testing: Evaluates genetic risk before symptoms appear, particularly valuable for individuals with a family history of diseases such as hereditary colorectal cancers.
- Carrier Testing: Conducted prior to family planning, especially for individuals from high-risk ethnic groups or with a family history of genetic disorders. It identifies carrier status in prospective parents.
- Pharmacogenetic Testing: Enables personalized medication selection and dosage optimization based on an individual’s genetic profile, improving treatment outcomes.
- Prenatal Testing: Detects genetic abnormalities during pregnancy, including conditions such as Down syndrome and Trisomy 18, using conventional screening methods or advanced cell-free DNA testing.
- Newborn Screening: Mandatory testing performed shortly after birth to identify conditions such as congenital hypothyroidism, sickle cell disease, and phenylketonuria (PKU), enabling timely medical intervention.
- Preimplantation Genetic Testing: Used during in-vitro fertilization (IVF), where preimplantation genetic diagnosis (PGD) screens embryos for genetic abnormalities to improve pregnancy success rates.
Genetic Testing’s Role in Disease Detection Driving Market Growth
Genetic testing, including prenatal and newborn screening, plays a vital role in identifying disorders such as thalassemia, Down syndrome, and cystic fibrosis. The increasing global incidence of genetic diseases is expected to significantly boost demand for genetic testing. According to the United Nations, approximately 3,000 to 5,000 children are born annually with Down syndrome worldwide. Data from the Cystic Fibrosis Foundation indicate that around 40,000 individuals in the United States live with cystic fibrosis, with approximately 1,000 new cases diagnosed each year. Additionally, the Indian Academy of Thalassemia reported that nearly 15,000 children are born with thalassemia annually in India, accounting for roughly 10% of global pediatric cases.

Rising Focus on Early and Preventive Care Fuels Demand
The growing emphasis on early diagnosis and preventive healthcare is a major driver of genetic testing adoption, particularly in the United States. Escalating healthcare costs associated with chronic disease management have encouraged healthcare systems and policymakers to prioritize early risk assessment. Cardiovascular diseases alone account for an estimated USD 320 billion annually in direct and indirect healthcare costs in the U.S. Genetic testing enables early identification of health risks, allowing for timely intervention and disease prevention. As a result, many private healthcare payers now include genetic testing within reimbursement frameworks, further supporting market growth. Increased coverage for rare disease testing has also contributed to broader adoption.
Competitive Landscape
The genetic testing market is highly competitive, with key players including Abbott Laboratories, Danaher Corporation, Thermo Fisher Scientific, Hoffmann-La Roche, QIAGEN, Illumina, Myriad Genetics, Bio-Rad Laboratories, DiaSorin/Luminex Corporation, CircleDNA, tellmeGen, 23andMe, AncestryDNA, Mapmygenome, Color Health, and MyHeritage, among others.

Strategic Initiatives Driving Market Expansion
Market participants are actively pursuing organic and inorganic growth strategies, such as product innovation, partnerships, and acquisitions, to strengthen their market presence and expand customer reach. Notable developments include:
- In June 2022, Prenetics Group Limited launched ColoClear by Circle, a non-invasive at-home screening test for early detection of colorectal cancer.
- In March 2022, Illumina introduced a comprehensive genomic profiling test for cancer in Europe, capable of analyzing multiple tumor genes and biomarkers through a single assay.
- In November 2022, Myriad Genetics acquired Gateway Genomics, integrating consumer-focused genetic testing solutions, including the SneakPeek Early Gender DNA Test, into its portfolio.
Looking ahead, the genetic testing market is expected to gain further traction due to the increasing adoption of next-generation sequencing technologies, rising disposable incomes, continuous technological advancements, expanding test availability, and aggressive growth strategies implemented by industry players.
