The Science Behind Invitae’s Products
Invitae offers assays for sequencing single genes, panels of genes, and exomes.
Full-gene sequencing: This is a targeted next-generation sequencing-based test in which clinically important regions of a gene are sequenced at 350X coverage. These important regions include the parts of the gene that code for a protein, called exons. In addition, Invitae typically sequences 10 to 20 base pairs flanking the exons (i.e. within introns).
Exome analysis: Invitae “Boosted Exome” test that allows one to capture all coding variants within ~20,000 coding genes across the entire genome. Learn more here. This test is available for affected individuals and their biological parents.
The major limitation of these assays is that they do not capture genetic variants within the non-coding regions of the genome (that are captured by whole-genome sequencing), which are known to play regulatory roles and may be associated with the risk of developing particular health conditions.

Review of Invitae Genetic Products
Invitae has three types of tests that can be ordered by individuals online. Customers receive a saliva collection kit in the mail. Diagnostic tests are performed in CLIA- and CAP-accredited laboratories. Test results will be reviewed by Invitae’s team of scientists, lab directors, and genetic counselors to ensure high quality. Moreover, healthcare providers can also order most of these tests for their patients through a HIPAA-compliant online portal, allowing genetic information to help guide how they care for their patients. Healthcare providers can also add additional genes to existing gene panels when ordering for patients. Patients login to their Invitae account to access their test results.
Review of Invitae Diagnostic Tests
Invitae offers diagnostic genetic testing for a number of different hereditary conditions, including hereditary cancers. These tests are appropriate for individuals that have a personal or family history of cancer, heart disease, neurological conditions, rare diseases, and pediatric conditions. These tests may be covered by insurance. According to Invitae, individuals typically pay between $0 and $100 out of pocket.
Providers can order from an even larger array of diagnostic tests.
Review of Proactive Tests
Invitae offers proactive genetic testing to healthy individuals that do not have a known family history of genetic conditions. This allows individuals to identify their risk of developing a particular disease in the future. Invitae thinks this is important because its research has suggested that ~15% of healthy adults carry a potentially serious health-related genetic risk.
Invitae offers three such proactive screening tests. These tests are not covered by health insurance.
Invitae Cancer Screen ($250). This screen analyzes 61 genes associated with the risk of developing an inherited form of cancer.
Invitae Cardio Screen ($250). This screen analyzes 77 genes associated with the risk of developing an inherited form of cardiovascular disease.
Invitae Genetic Health Screen ($350). This screen analyzes 147 genes associated with the risk of developing an inherited form of cancer, cardiovascular disease, and a number of other diseases. This test is available to both Americans and Canadians.
Review of Reproductive Tests
Invitae offers reproductive genetic testing for patients before, during, and after pregnancy. These tests include:
Carrier Screening ($250). Before or during pregnancy, couples in the United States and Canada can obtain information about if their child is at risk of inheriting a genetic disease.
A carrier is an individual that has a variant in one copy of a gene that is associated with a disease, which can be passed down to a child. Invitae offers testing for up to 288 carrier disorders. For example, this test can detect muscular dystrophy among other conditions. Most testing is done for disorders that are autosomal recessive, which are disorders that require both parents to be carriers for the same disorder. Some testing is done for X-linked disorders, meaning that the gene associated with the disorder is located on the X chromosome.
*Non-Invasive Prenatal Screening (NIPS). This test analyzes small fragments of DNA, otherwise known as cell-free DNA, that are circulating in the blood to screen for common genetic disorders, such as Down Syndrome, Edwards Syndrome, and Patau Syndrome, that result from additional or missing pieces of genetic material in a child’s genome, called chromosomes. NIPs can be performed as early as 10 weeks into a pregnancy.
*Prenatal Diagnostic Testing. Invitae offers two microarray-based tests, one that identifies genetic variants across the whole genome and one that is targeting genetic variants in selected genes with known clinical significance. This service is useful to confirm a positive or negative NIPS result. It can only be performed during pregnancy.
*Preimplantation Genetic Testing (PGT). This test can help identify viable embryos for transfer during in vitro fertilization (IVF).
*Pregnancy Loss. Invitae offers a chromosomal microarray analysis (CMA) for pregnancy loss, in which very small deletions or duplications of DNA sequences can be detected. This can allow individuals to potentially uncover the cause of recurrent miscarriage or stillbirth.
*These tests can only be ordered by a healthcare provider and may be covered by insurance.
Genetic Counseling Services
Genetic testing can be stressful and confusing. In general, tested individuals do not have direct access to healthcare professionals trained in genetics and counseling that can help explain what their test results mean for themselves and their family members. Invitae has an extensive list of genetic counseling resources on its website. Customers can speak with a board-certified genetic counselor by phone after they have received their testing results at no additional cost.
Invitae accepts insurance from most payers. The process is intended to be simple as Invitae works directly with the insurance companies to coordinate payment, otherwise known as filing a claim to insurers, and this usually results in patients paying $0 to $100 out of pocket. Most insurance companies will cover tests ordered by a physician for diagnostic purposes. For example, tests to determine if a hereditary condition could be passed to future children, understand the genetic cause of unexplained symptoms, or to better understand an inherited disease.
Some Invitae customers, as well as customers of other clinical genetic testing services, have discussed getting “hit with surprising bills.” This happens because different insurance companies choose to reimburse different genetic tests and sometimes may only cover part of a test. Other insurance companies may not reimburse a test at all if they don’t deem it “medically necessary.”
Invitae strips personal identifiers, such as name and date of birth, from customers’ data. With this, the company reserves the right to share anonymized or aggregated data with third parties. Invitae also shares personal information, not genetic data, with service providers, business partners, and third parties. However, every 6 months, the company does share information about genetic variants discovered from collected data with a third party database of genetic variants, ClinVar, which is managed by the National Center for Biotechnology Information and National Institutes of Health. This policy was put in place because the American College of Medical Genetics (ACMG) highlighted the importance of sharing clinical genomic data to improve health care.
Invitae in the News
Invitae presented a study at the American College of Medical Genetics and Genomics annual meeting in 2019 highlighting a problem with consumer genetic tests called the “clinical false-negative result.” Specifically, the Invitae study outlined that the many individuals who had undergone BRCA1 and BRCA2 genetic testing for breast and ovarian cancer risk by 23andMe were wrongly given negative results. This is because of 23andMe genotypes only three genetic variants, known as founder mutations, within BRCA1 and BRCA2, whereas Invitae uses sequences the entire BRCA genes. Therefore, after testing 100,000 individuals, Invitae determined that 5% of these individuals had BRCA mutations known to increase the risk of developing breast or ovarian cancer. Among these individuals who tested positive, Invitae determined 94% of non-Ashkenazi Jewish individuals and 19% of Ashkenazi Jewish individuals harbored mutations that would have been missed by the 23andMe test.
Invitae has also been scrutinized. A genetic counselor discovered that the Invitae test missed a case of Lynch syndrome, which increases the risk of developing several types of cancers. When the patient was re-tested 11 months later, he or she tested positive. This led to Invitae having to retest over 50,000 samples and implement additional quality measures to ensure fewer testing errors.
- One of the first clinical genetic testing companies.
- A large collection of single-gene tests.
- Access to genetic counselors, supporting an informed customer experience.
- Health insurance can cover the costs of some tests.
- More expensive than other genetic tests on the market.
- No differentiated scientific qualities.
In this final part of our Invitae review, we will compare it to Nebula Genomics.
Nebula Genomics offers a 30x Whole-Genome Sequencing service that decodes 100% of your DNA for $299. In contrast, Invitae and other clinical laboratory-based genetic tests cost hundreds of dollars to test a single gene. Although Nebula Genomics is not a diagnostic test, our 30x whole-genome sequencing data is produced in CLIA/CAP-accredited laboratories and thus can be used by healthcare providers and genetic counselors. Ultimately, if an individual has a known family history of a genetic disorder, we recommend consulting a healthcare provider first.
Here is how Nebula Genomics compares with Invitae’s genetic tests.
