Notice of Privacy Practices


Diagnostic Laboratory of Oklahoma (DLO), an Affiliated Covered Entity of Quest Diagnostics, is committed to protecting the privacy of your identifiable health information. This information is known as “protected health information” or “PHI.” Examples of documents that may contain your PHI include laboratory test orders, test results and invoices.

Our Responsibilities
DLO is required by law to maintain the privacy of your PHI. We are also required to provide you with this Notice of our legal duties and privacy practices upon request. It describes our legal duties, privacy practices and your patient rights as determined by the Health Insurance Portability and Accountability Act of 1996 (HIPAA). We are required to follow the terms of this Notice currently in effect. We are required to notify affected individuals in the event of a breach involving PHI that is unsecured. PHI is stored electronically and is subject to electronic disclosure. This Notice does not apply to certain services that we perform, such as some drugs of abuse testing services and insurance applicant services.

How We May Use or Disclose Your Health Information
We use your PHI for treatment, payment, or healthcare operations purposes and for other purposes permitted or required by law. Not every use or disclosure is listed in this Notice, but all of our uses or disclosures of your PHI will fall into one of the categories listed below.

We need your authorization to use or disclose your PHI for any purpose not covered by one of the categories below. With limited exceptions, we will not use or disclose psychotherapy notes, use or disclose your PHI for marketing purposes or sell your PHI unless you have signed an authorization. You may revoke any authorization you sign at any time. If you revoke your authorization, we will no longer use or disclose your PHI except to the extent we have already taken action based on your authorization.

We may use and disclose your PHI for the following purposes:

DLO provides laboratory testing for physicians and other healthcare professionals, and we use your PHI in our testing process. We disclose your PHI to authorized healthcare professionals who order tests or need access to your test results for treatment purposes. We may use and disclose PHI to contact you to remind you of an appointment or to tell you about our health-related products and services that may be of interest to you. Examples of other treatment-related purposes include disclosure to a pathologist to help interpret your test results or use of your PHI to contact you to obtain another specimen, if necessary.

DLO may use and disclose your PHI for purposes of billing and payment. For example, we may disclose your PHI to health plans or other payers to determine whether you are enrolled with the payer or eligible for health benefits or to obtain payment for our services. If you are insured under another person’s health insurance policy (for example, parent, spouse, domestic partner or a former spouse), we may also send invoices to the subscriber whose policy covers your health services.

Healthcare Operations
DLO may use and disclose your PHI for activities necessary to support our healthcare operations. This includes functions such as performing quality checks on our testing, internal audits, arranging for legal services or developing reference ranges for our tests. It also includes, for example, the sale, transfer, merger, or consolidation of all or part of DLO and/or Quest Diagnostics with another covered entity, or an entity that following such activity will become a covered entity and due diligence related to the transaction(s).

Business Associates
We may provide your PHI to other companies or individuals that need it to provide services to us. These other entities, known as "business associates," are required to maintain the privacy and security of PHI. For example, our business associates may use your PHI to conduct billing, collections, imaging, courier, or record storage services on our behalf.

Individuals Involved in Your Care
We may disclose relevant PHI to a family member, friend, caregiver or other individual involved in your healthcare or payment for your healthcare, if you tell us that this is acceptable to you or you do not object; or if in our professional judgment, we believe that you do not object.

As Required by Law
We may use and disclose your PHI as required by law.

Law Enforcement Activities and Legal Proceedings
We may use and disclose your PHI if necessary to prevent or lessen a serious threat to your health and safety or that of another person. We may also provide PHI to law enforcement officials, for example, in response to a warrant, investigative demand or similar legal process, or for officials to identify or locate a suspect, fugitive, material witness, or missing person. We may disclose your PHI as required to comply with a court or administrative order. We may disclose your PHI in response to a subpoena, discovery request or other legal process in the course of a judicial or administrative proceeding, but only if efforts have been made to tell you about the request or to obtain an order of protection for the requested information.

We may use or disclose PHI for research purposes when permitted by law, such as when an Institutional Review Board or privacy board has reviewed the research proposal and plans to ensure the privacy of your PHI and determined that your authorization is not required. We may also use or disclose PHI about deceased patients to researchers if certain requirements are met. We may use and disclose a limited data set containing some of your PHI for research purposes. However, we will only disclose a limited data set if we enter into a data use agreement with the recipient. The limited data set does not contain any information that can directly identify you.

De-identified Information

We may use your PHI to create "de-identified" information which means that we remove information that can be used to identify you. There are specific rules under the law about what type of information needs to be removed befroe information is considered de-identified. Once information has been de-identified as required by law, it is no longer PHI and we may use it for any lawful purpose.

Other Uses and Disclosures
As permitted by HIPAA, we may disclose your PHI to:

  • Social Services Agencies
  • Public Health Authorities
  • The Food and Drug Administration
  • Health Oversight Agencies

Incidental Uses and Disclosures
Sometimes, your PHI may be used or disclosed in the course of our primary uses and disclosures, such as for treatment, payment or healthcare operations. For example, we may call your name in the waiting room at one of our Patient Service Centers, or use it in a telephone conversation with a provider. We are permitted to makes such incidental uses and disclosures as long as we take reasonable steps to minimize them, and have in place appropriate safeguards to protect them.
