Sema4 was founded by Eric Schadt PhD at the same time as its parent company Sema4 Holdings and was the first service the corporation offered. The company was created out of the Ichan School of Medicine (ISM) at Mount Sinai health system. It was formed in 2017 with a focus on providing high-quality healthcare services to patients.
The company founders sought to provide transforming healthcare in women's health and cancer for all patients. Right from the start, the company utilized the combination of AI and human genetics for test and diagnosis, and to date, all its added products take advantage of these technologies. They also engage in active genomic research that encompasses data science and engineering, network modeling, and molecular profiling.
A patient-centered health intelligence company
The executives as of 2021 are Kareem Saad, Tony Prentice, Karen White, and others. Its headquarter is in Stamford, Connecticut, United States, and it performs tests throughout the United States.
Sema4 is patient-focused. However, the company does not directly perform tests for patients but offers them through a patient's physician.
Sema4 became a public firm trading on Nasdaq in 2021.

Sema4 is a genetic and AI-enhanced test firm dedicated to patients interested in learning about certain underlying conditions that they experience due to their ancestry and genetics. It also offers next generation genetic sequencing for people who are not yet experiencing symptoms but suspect that their familial line may have a particular condition to which they are susceptible.
The firm aims to accelerate the development and scaling of its health intelligence platform so as to enhance precision medicine and treatment for these conditions. While it is clearly focused on ensuring that patients and doctors trust its algorithms and test results for various conditions it offers solutions on, it also seeks to make its pricing cheaper and competitive.
Sem4 doesn't just perform tests like an average genetic testing company. While it does not offer a Whole-Genome Sequencing, its test panels are highly specific and enhanced to give the best possible health information on a particular condition.
These tests must be ordered by a physician, who will sign up with login details. Patients and their doctor will consult on the appropriate test, which can be ordered from the test catalog on the company website. For each test, the physician is provided with a provider brochure, a requisition form, and a genetic testing consent form.
Specimen requirements are included with each test. Usually, this will be a small blood, saliva, or cheek swab sample, which will be collected at the doctor's office. They will then send the sample and accompanying paperwork to the Sema4 lab.
After submission, the sample will be analyzed and results will be available usually between 2-4 weeks. Patients will receive notice on the availability of their results. A genetic counselor may contact them to explain the results if it is convenient and offer advice and answer questions.
While the company does not offer genetic testing on every condition, it has over a hundred panels in its test catalogs that users can register for to know their susceptibility or nature of a particular condition.
Signal Hereditary Cancer panels are designed to help give extremely accurate and personalized tests to allow patients the knowledge if they have the genes that make them susceptible to hereditary cancer.
The Signal Hereditary Cancer test covers 18 panels, including a universal test panel that includes 107 genes. The other 17 panels are cancer type specific but also cover several genes.

Patients can also explore other cancer testing options that include WES/WTS, PanCancer, and solid tumor tests.
The company notes it's oncology solutions can be used individually, or in combination to provide holistic care. It's largely technology driven approach aims to identify, treat, and monitor cancer in patients.
Sema4 holistic approach to oncology
The Expanded Carrier Screening is one of the newest innovations of Sema4 dedicated to women and child health. This screening test is designed for pregnant and expectant mothers to make healthier choices for the future of their unborn kids. The ECS is one of the most comprehensive and accurate carrier screens that help expectant mothers know the likelihood of transferring a genetic condition to their unborn child. This test is often used in combination with the company's noninvasive prenatal testing.
Sema4 reproductive and prenatal testing options
The test uses the latest technologies to calculate the possibilities of genetic susceptibility to an unborn child. To perform the test, a patient will only need to provide a blood or saliva sample and get access to accurate risk precision of their child susceptibility.
Along with newborn screening and hereditary cancer tests, the reproductive and prenatal testing is part of a larger cohort of tests for Women's Health.
Sema4 is highly dedicated to ensuring better health for women and, as such, offers various test panels on different stages of a woman's life.
The company offers gold-standard testing for carrier screening, noninvasive prenatal testing, postnatal testing, as well as preventative hereditary cancer testing.
Options for women's health testing
Postnatal testing detects 193 childhood conditions, many of which can't be detected by carrier screening, standard prenatal tests, or state newborn screening alone. It also includes a pharmacogenomic (PGx) analysis of a child's response to more than 40 medications that may be prescribed during childhood, including common antibiotics.
Sema4 uses advanced data engineering and data science approaches to effectively leverage vast patients' genomic and clinical data in creating better medicine and drug development. The company seeks to deliver value at the pre-clinical, clinical, and commercial drug development stages for biopharma companies.
Sema4 has world-leading expertise and capabilities complemented by an interdisciplinary team of scientists, clinicians, and data engineers powered by one of the leading genomics laboratories to discover new possibilities and blaze new trails for drug production.
Sema4 works with biopharma companies
Companies and health care systems can contact the company to establish partnerships.
This service is only available after testing results have been returned to the patient and a positive result and/or genetic variants of uncertain significance (VUS) are discovered. An expert counselor will contact you to explain the results. The counselor will also give advice on how the results will affect the patient and their family.
Sema4 is a diagnostic test ordered through physicians and thus is usually covered through insurance billing. The company works with most major insurances including Aetna, Blue Cross Blue Shield, Cigna, Humana, and United Healthcare. Billing specialists are available for patients interested in learning more about how much can be covered.
There are different types of results for different tests. However, each has the analytical part and the summary part. The sample report for hereditary cancer shows the summary section of the result, which clearly identifies a positive pathogenic variant and the type of disease that this variant may affect.

The reports can be from 5-20 pages long. After the summary page, more analytical information is provided for the health professional to help identify details of the diagnosis.
Prenatal and postnatal carrier screens will look similar and present relevant findings related to genes that pose risk of developing genetic disorders.
Sema4 has a good privacy policy that is user-centered and ensures that no private information is mishandled. Users can trust the company to securely protect their data and keep it away from unauthorized parties. The company privacy policy explicitly states that all information, including personal details collected from patients, is solely used for testing and diagnostic purposes.
However, the company may share users' data with their partnering bodies when necessary, especially in providing better tests and diagnosis.
The company also has a notice on privacy practices that give specific information on how it handles protected health information.
Sema4 employees generally have good things to say about the company, ranking it with 4 out of 5 stars on Glassdoor. Notable reviews today announced that they learned a lot from good lab experience but upper management experience at sema4 could be improved.
