How Long Are Opiates Detectable in Urine?
Opiates are typically detectable for around one to three days.
The detection window differs between people and substances.
Dose, frequency, metabolism and collection timing affect detection.
Compare drug detection times in urine and blood.
Can Prescription Medicines Affect the Result?
Some prescribed medicines can produce expected opiate findings.
Declare relevant medicines when instructed during the testing process.
Never stop prescribed treatment solely for a drug test.
What Does the Result Mean?
The initial screen uses a 300 ng/ml cut-off.
A negative result falls below that screening cut-off.
A positive screen proceeds to confirmatory laboratory testing.
The laboratory issues the final documented result.
What the Result Cannot Show
It cannot determine the exact consumption time.
It cannot calculate the amount taken.
It cannot prove current intoxication or impairment.
A negative result cannot exclude earlier opiate use.
