Privacy Notice

We know that privacy is important to you. Your privacy is important to us too. This Notice explains how Quest Diagnostics and its affiliates (“Quest”, “we”, “our”) collect information from or about you (“you” or “your”) when you visit the websites or any applications, social media networks, interactive features, and other services that link to this Notice (the “Platforms”), and how we use, maintain, protect and disclose that information.

If you are using our Platforms in connection with our HIPAA covered services, please refer to our HIPAA Notice of Privacy Practices, which describes how we use and disclose your protected health information, our legal duties with respect to your protected health information, and your rights with respect to your protected health information and how you may exercise them. In connection with HIPAA covered services, in the event of conflict between this Notice and our HIPAA Notice of Privacy Practices, our HIPAA Notice of Privacy Practices will prevail.

Information We Collect

We may collect information about you including non-personally identifiable information and/or “Personal Information,” which is information that may identify, relate to, describe, or be capable of being associated with or reasonably linked, directly or indirectly, with a particular identified or identifiable person or household.

Personal Information we might collect includes data such as the following:

We do not consider Personal Information to include information that can no longer be used to identify a specific natural person, whether in combination with other information or otherwise. For example, de-identified or aggregated consumer information.

Additionally, the following types of information are not considered Personal Information:

• publicly available information from government records; or
• information excluded from the applicable data privacy law’s scope, including but not limited to PHI covered by HIPAA, information derived from PHI that is de-identified in accordance with HIPAA, and personal information we handle in our capacity as a service provider to a business.

If we combine non-personally identifiable information with Personal Information, we will treat such information appropriately, but not all rights may apply to the non-personally identifiable information portion.

How We Use Personal Information That We Collect for Business or Commercial Purposes

We may use your Personal Information:

• to fulfill the purposes for which the information was provided (e.g., to provide a service or perform on a contract); to identify you in order to respond to requests, provide services or products, personalize information we provide to you, or otherwise as described below;
• to communicate with you about your account or our relationship, such as making announcements about the Platforms or our privacy policies and terms;

• to design, improve and administer our Platforms;
• to improve our products and services;
• to recruit and evaluate job applicants and candidates for employment and to conduct background checks;
• to engage in the ordinary course of employment (e.g., facilitate onboarding processes, manage compensation, provide benefits, review performance, etc.) and for other internal human resources purposes;
• to audit and measure user interaction with our Platforms, so we can improve the relevancy or effectiveness of our content and messaging;
• to develop and carry out marketing, advertising and analytics;
• to improve and develop search engine optimization/enhancement to help search engines find and display our content more effectively;
• to provide texts or emails containing information about our products or services, or events or news, that may be of interest to recipients, as permitted by law;

• debugging to identify and repair errors;
• to protect our rights and to protect your safety or the safety of others;
• to investigate fraud or respond to government inquiries;
• to complete corporate transactions (from time to time, we sell, buy, merge or otherwise reorganize our businesses, and these corporate restructurings may involve disclosure of Personal Information to prospective or actual purchasers, or the receipt of it from sellers);
• to comply with laws, regulations or other legal process; or
• otherwise use your Personal Information with your consent.

We may also use your Personal Information to:

• provide you with the services and products you request or that have been ordered and/or requested by your healthcare provider;
• process or collect payments for our services; or
• respond to your questions and otherwise provide support you request.

We may use Precise Location Data from your device in accordance with the device’s consent process on some of our Platforms to help us improve your user experience and provide information that is relevant to you, such as nearby Patient Service Center locations.

When you choose to print or email one of your results from within the MyQuest application, the result file is temporarily stored on your mobile device to aid in more efficient delivery of your result.  The result file will be deleted from your mobile device storage once the action of printing or emailing is complete.

How Long We Retain Your Personal Information

Quest Diagnostics retains your Personal Information only for as long as is necessary for our legitimate business purposes. We will retain and use your Personal Information to the extent necessary to comply with our legal, accounting, or reporting obligations (for example, if we are required to retain your data to comply with applicable laws), resolve disputes and enforce our legal agreements and policies. Additionally, we may continue to store your Personal Information contained in our standard back-ups. This applies to all categories of Personal Information in use by us. 

Selling Personal Information or Disclosing of Personal Information for Targeted Advertising

We do not sell Personal Information. We may disclose the following categories of Personal Information to the categories of third parties listed below for the purpose of targeted or cross-context advertising (under California law, this is called “Sharing”):

No text message opt-in status information will be shared with or sold to third parties/affiliates for their own marketing/promotional purposes. Text messaging originator opt-in data and consent information will not be shared with any third parties, including affiliate or business partners. We also use and disclose your information pursuant to a subpoena, court order or other legal process, to establish or exercise our legal rights, or defend against legal claims. The opt-in is not transferable to another party involved in the process.

Cookie Notice

Our websites, like almost all other websites, use cookies and other technologies to make the website work as you expect and to collect and share information. Please see our Cookie Notice for more information.

Keeping Your Information Secure

Quest Diagnostics has adopted physical, technical and administrative measures that are designed to prevent unauthorized access or disclosure, maintain data accuracy, and ensure appropriate use of Personal Information. We cannot, however, ensure or warrant the security of information. No security measures are infallible.

How can you help protect your information?

If you are using a Quest Diagnostics Platform for which you registered and chose a password, you should not divulge your password to anyone. We will never ask you for your password in an unsolicited phone call or in an unsolicited email. Also, remember to sign out of the Quest Diagnostics Platform and close your browser window when you have finished your work.

Please note that unencrypted email is not a secure method of transmission, as information in such emails may be accessed and viewed by others while in transit to us. For this reason, we prefer that you not communicate confidential or sensitive information to us via regular unencrypted email. We will, however, honor patient requests for communications through unencrypted email.

Links to Other Sites

Our Platforms may be accessed from or contain links to other websites that we do not own or operate. If you access those links, you will leave our Platforms. Quest does not control those third party websites or their privacy practices, which may differ from ours. We do not endorse or make any representations about third-party sites, including about the content or security of those sites. The information you choose to provide to or that is collected by these third parties is not covered by this Notice. 

Children's Privacy

We do not knowingly collect information from children (as defined by COPPA) and we do not target our Platforms to children. If we learn that we have collected any information from children, we will delete it. For more information about the Children’s Online Privacy Protection Act (“COPPA”), which applies to websites that direct their services to children under the age of thirteen (13), please visit the Federal Trade Commission’s website https://www.ftc.gov/tips-advice/business-center/guidance/complying-coppa-frequently-asked-questions.

Notice of Right to Opt-Out

Residents of California have a right to direct businesses not to sell their Personal Information or share their Personal Information for targeted advertising. Residents of other certain U.S. states have the right to direct businesses not to process their Personal Information for other specified purposes, which may include: (i) targeted advertising, (ii) sale, or (iii) profiling in furtherance of decisions that produce legal or similarly significant effects concerning the consumer. This is known as the “right to opt out.” We do not sell your Personal Information. However, when you visit our websites, we may share information about your use of our website with our advertising and analytics partners. You can opt out of sharing or using your Personal Information for the purposes of targeted advertising, by interacting with the cookie banner that may appear at the bottom of Quest websites the first time you come to the website or the “Your Privacy Choices” link that may appear in the footer of our websites. You can also opt back into these cookies through the same link. We do not use your Personal Information for profiling to make decisions that would have a legal or similarly significant effect concerning you.

Right to Non-Discrimination for the Exercise of a Consumer’s Privacy Rights

You have a right not to receive discriminatory treatment by Quest for exercising any of your privacy rights conferred by your state’s consumer privacy laws. Quest will not discriminate against any consumer because such person exercised any of the consumer’s rights under these privacy laws, including, but not limited to:

• denying goods or services;
• charging different prices or rates for goods and services, including through the use of discounts or other benefits or imposing penalties;
• providing a different level or quality of goods or services; or
• suggesting that the consumer will receive a different price or rate for goods or services or a different level or quality of goods or services.

Quest may, however, charge a different price or rate, or provide a different level or quality of goods or services, if that difference is related to the value of your data.

Making a Request, Appeals, and Authorized Agents

To make a request to exercise your privacy rights you may visit our online request form. You may also call (833) 341-0196. To exercise your right to appeal, you may email us at privacy@questdiagnostics.com and include the Request ID from your previous request. 

Certain state residents may designate an authorized agent to make a request on your behalf. We will comply with requests made by authorized agents as required by applicable law. We will deny requests from agents that do not submit proof of authorization from you. To verify that an authorized agent has authority to act for you, we may require a copy of a power of attorney or require that you provide the authorized agent with written permission and verify your own identity with us.

We will confirm our receipt of your request within 10 days. If you have not received a response within a few days after that, please let us know by contacting us at the webpage or phone number listed above. We will respond to your request within 45 days. If necessary, we may need additional time to respond, up to another 45 days, but we will reply either way within the first 45-day period and, if we need an extension, we will explain why.

For certain types of requests, we may need to verify your identity. In those cases, you will need to provide us with certain information such as your name, email address, physical address, or other information, as relevant, so that we can verify that you are who you say you are. Which information may depend on the type and sensitivity of information requested.

In certain cases, we may deny a request. For example, we may deny a request if we cannot verify your identity or if providing you the information could create an unreasonable risk to someone’s security (for example, we do not want very sensitive information disclosed inappropriately), or we may deny a request for deletion if the law requires that we maintain the information (e.g., to comply with federal and state medical record retention requirements); or, if we need the information for internal purposes such as to continue to provide you services. If we deny your request, we will explain why we denied it.

International Transfer of Your Personal Information

Your personal information may be transferred to, stored, and processed in a country other than the one in which it was provided, including transfers to the U.S. (i.e., a 'Recipient' country). Quest Diagnostics will use mechanisms for any such transfer as required under applicable law. If You have questions concerning the transfer of your Personal Information, please contact us using the contact details set out below.
