Sema4 Genetic Testing Login: 5 Critical Steps To Access Your Results After The GeneDx Name Change
If you are searching for the Sema4 genetic testing login, the most critical piece of information you need to know is that the company has officially changed its name. As of January 9, 2023, Sema4 Holdings Corp. is now known as GeneDx Holdings Corp. (NASDAQ: WGS). This significant corporate change means that the portal, login process, and result access mechanisms have been updated to reflect the new GeneDx brand. This article, updated for December 2025, provides the definitive, step-by-step guide to navigating this transition and securely retrieving your genetic test results, whether you are a patient or a healthcare provider.
The transition from Sema4 to GeneDx was part of a strategic move to focus on delivering personalized and actionable health insights through advanced genomic testing, particularly exome and genome sequencing. For patients who underwent testing under the Sema4 name, your data is secure and accessible through the new GeneDx platforms, though the exact method of access depends on your user type and the date of your test.
The Sema4-to-GeneDx Transition: Understanding Your Current Login Options
The search term "Sema4 genetic testing login" is now a legacy keyword. The company's operations, including the patient and provider portals, now function under the GeneDx umbrella. GeneDx is committed to providing a secure, HIPAA-compliant way for all users to access their information.
1. Patient Access: Using the GeneHome Portal
For patients seeking to view their genetic test results, the primary portal is now called GeneHome. This platform is designed to be the central point of contact for patient-facing services at GeneDx.
- What is GeneHome? GeneHome is the current patient portal for GeneDx, replacing or integrating with the functions of the former Sema4 patient portal, which was built on the Centrellis health intelligence platform.
- Login Process: To begin, you will typically enter your email address on the GeneHome sign-in page to start the process of accessing your account. If you had a previous Sema4 account, your credentials may have been migrated, or you may need to follow the "Forgot your password?" or "Sign up now" prompts to link your existing data.
- Accessing Results: While the portal provides a secure mechanism for result delivery, it is important to remember that your ordering healthcare provider or clinic is often the fastest and most direct source for your official genetic counseling report and test results.
2. Provider Access: The GeneDx Provider Portal
For healthcare providers, clinicians, and medical staff who ordered tests through Sema4, the workflow has been consolidated into the GeneDx Provider Portal.
- Key Functions: This portal is a fast, efficient, secure, and HIPAA-compliant system used for multiple critical tasks:
- Ordering new genetic tests (e.g., exome, genome, hereditary cancer testing).
- Tracking the status of pending tests.
- Sharing clinical notes with the GeneDx team.
- Receiving and viewing patient test result reports.
- Login Details: Providers sign in with their registered email address and password. If you are a new user or a former Sema4 provider experiencing issues, there is a clear process on the GeneDx website for creating a new portal user account.
5 Critical Steps to Retrieve Your Sema4 (GeneDx) Genetic Test Results
If you are a patient who had testing done when the company was still Sema4, follow these steps to ensure you can access your records and results without unnecessary delay.
Step 1: Confirm the Name Change and Destination URL
Always start by recognizing that you are looking for the GeneDx portal, not the old Sema4 portal. The official website is now GeneDx.com. Be wary of any non-official or outdated links that still prominently feature the old Sema4 branding without mentioning the GeneDx transition.
Step 2: Utilize the GeneHome Patient Portal Login
Navigate directly to the GeneDx patient login page. Look for the "GeneHome" sign-in area. Use the email address you provided when the genetic test was ordered. If you encounter issues, proceed to Step 3.
Step 3: Contact Your Ordering Healthcare Provider
This is often the most reliable and fastest method. Genetic test results are first sent directly to the ordering physician, genetic counselor, or clinic. They are best equipped to interpret the results and provide the necessary post-test consultation. Contacting their office is the recommended first action if you cannot immediately access the results online.
Step 4: Request Medical Records Directly from GeneDx
If you require additional copies of your medical records, or if your ordering provider is no longer available, you can submit a formal request to GeneDx. This process involves downloading and completing the official Medical Record Release Form from the GeneDx website.
- Important Note: The processing of a medical record release request can take up to 60 days from the date of receipt of the completed and signed form.
- Exclusions: Be aware that genetic ancestry information is typically not available through this medical record request process.
Step 5: Utilize Support and Contact Channels
For persistent login issues, questions about your Electronic Health Records (EHR), or general inquiries about the Centrellis data platform legacy, use the official GeneDx contact information. The company maintains dedicated support channels for both patients and providers to address access and billing questions related to various services, including Non-invasive Prenatal Testing (NIPT) and hereditary cancer screens.
Topical Authority: The Legacy of Sema4 and the Future of GeneDx
The original Sema4 company was known as a patient-centered health intelligence company that leveraged AI and machine learning to analyze genomic and clinical data. The core of this operation was the Centrellis health intelligence platform, which was designed to organize and interpret complex data to inform diagnosis, direct treatment, and improve drug discovery.
GeneDx continues this mission, focusing heavily on exome and genome sequencing to diagnose complex genetic disorders quickly. The comprehensive test catalog includes a wide range of genetic testing services, such as:
- Hereditary Cancer Testing: Identifying inherited risks for various cancers.
- Non-invasive Prenatal Testing (NIPT): Screening for common chromosomal abnormalities during pregnancy.
- Carrier Screening: Assessing the risk of passing on genetic conditions to children.
- Exome Sequencing: Analyzing the protein-coding regions of the genome to find the cause of rare or complex disorders.
- Pharmacogenomics (PGx) Testing: Analyzing how a patient’s genes affect their response to drugs.
The current GeneDx Provider Portal and GeneHome patient portal are the modern interfaces for accessing the results generated from these advanced diagnostic tools. The transition from Sema4 to GeneDx represents a consolidation and refinement of these services, ensuring the continued delivery of accurate, actionable, and accessible genetic insights to both patients and the broader medical community.
In summary, the key to the "Sema4 genetic testing login" is to pivot your search to GeneDx. Whether you are looking for the Provider Portal to manage orders or the GeneHome patient interface to view your results, the new GeneDx branding and website are the correct destinations for all your genetic testing needs and historical Sema4 data access. Always prioritize contacting your ordering physician first, as they hold the primary copy of your official genetic test report.
