D-Opioid Use — Number Received in the Last 7 Days or Since Admission/Reentry, If Less Than 7 Days
A medication-history measure that records how many D-opioids were received during the previous 7 days or a shorter period since admission or reentry.
This count helps clinicians review recent opioid exposure and guide safe treatment; it does not by itself diagnose misuse or addiction.

What is this test?
This is a clinical history or medication-reconciliation item rather than a blood or urine laboratory test. It counts the D-opioids received during the previous 7 days, or since admission or reentry when that period is shorter.
Why might I need this test?
Clinicians may use this information to review recent pain treatment, monitor safety during recovery or hospitalization, and plan pain management or medication adjustments. The count may also help with continuity of care after admission or reentry.
How is the test performed?
The information is usually obtained by reviewing medication administration records, discharge documents, and other health records, and by asking the patient about recent doses. The clinician verifies the medication names, doses, and dates when documenting the count.
How do I prepare for the test?
Bring an updated medication list and be ready to identify every opioid taken or received, including the dose, date, and reason. Do not stop or change prescribed medication on your own; discuss any concerns with the healthcare team first.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The recorded count can show the frequency and amount of recent D-opioid exposure, but it must be interpreted alongside the prescribed treatment, timing, symptoms, and other medical history. A higher or lower count does not by itself establish addiction, misuse, intoxication, or withdrawal, and the meaning of “D-opioid” may depend on the source record.
