Toxicology: Results, Reporting, & Services

Quest Diagnostics offers results in a variety of reporting methods to make the information easily accessible to the physician in a timely manner.

Communicating Urgent Results

The provider who requests a test is responsible for providing 24-hour reliable contact information for STAT and priority reporting. The person notified should be the ordering provider or her/his authorized representative as permitted or required by state and federal law, and who has the responsibility of interpreting the result in the context of the patient’s clinical condition and can take immediate action, if needed. If the person notified is not qualified to make these decisions, he/she has the responsibility to communicate the information to a qualified person immediately.

STAT test results will be reported for tests that have been ordered as STAT by the client and are offered as a STAT test by the Quest Diagnostics laboratory receiving the specimen. We will use reasonable efforts to promptly communicate STAT test results at any hour of the day, seven days/week.

Priority Result Reporting

Our Priority Result Reporting Policy includes special notification for results that may require attention by the healthcare provider prior to regular delivery of results. The priority result reporting is in addTwo doctors talking with laptopition to the regular reporting procedures for all test results. Clients may review our Priority Values on the Quest Diagnostics website. Because no list of critical and priority values satisfies every clinical situation, we allow for a limited degree of customization to suit your practice requirements. To customize your critical or priority values, contact Client Services at 866-MYQUEST (1-866-697-8378).

Priority-1 test results include, but are not limited to, results considered “critical” according to the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and the College of American Pathologists (CAP) Laboratory Accreditation Program and so designated by the Chief Laboratory Officer or designee. Because test results cannot be fully interpreted without knowledge of the patient’s current clinical condition and treatment, we will use reasonable efforts to promptly communicate Priority-1 results at any hour of the day, seven days/week so that the healthcare provider can determine the clinical implications and possible need for immediate attention.

Priority-2 test results are those that may require attention prior to the receipt of routine laboratory reports. We will use reasonable efforts to promptly communicate these results the same day (up to 7pm) or the next morning (after 7am), seven days/week. For facilities that are known to us as a nursing home or hospital, we will use reasonable efforts to promptly communicate these results at any hour of the day,
seven days/week. Tests marked Priority 2WD are called between 7 am and 7 pm weekdays.

Priority-3 reporting applies only to customers whose sole means of obtaining Quest Diagnostics laboratory results is the printed report (i.e., receiving only mailed or courier-delivered reports) and to clients who have requested Priority-3 reporting in writing. These are test results that may require attention before receipt of the printed report and will be called during weekday working hours.

Reissued Reports

These are patient medical reports that are reissued with changes or addendums to the previously-delivered report. After the change or addition is made, they are sent to the client again with these designations:

Revised: Any change in test result(s)

  • Amended: A change in the age/DOB or gender that affects the reference range of previously-reported test results or how the results are flagged (e.g., abnormal)
  • A change in client-provided information (e.g., clinical information from the requisition form) previously-reported, with no change in actual test result values
  • Addendum: New, or additional, information added to a previously-reported result
  • Confirmatory: Indication that a repeat test request was performed and the previously-reported results are confirmed
