What is the cutoff level for morphine?
What is the cutoff level for morphine?
The Department of Defense had established an im- munoassay cutoff of 2000 ng/mL in 1994 and a GC-MS cutoff of 4000 ng/mL for morphine. Both programs mandated testing for 6-AM with a cutoff of 10 ng/mL.
What is ng/mL mean?
Nanograms per milliliter
Nanograms per milliliter, abbreviated ng/mL, is the unit of measure most commonly used to express drug testing cut-off levels and quantitative test results in urine and oral fluid. A nanogram is 10-9 grams.
How many ng/mL are in Adderall?
Adderall is a 3:1 mixture of d- and l-enantiomers of amphetamine salts. Peak amphetamine concentrations ranged from 2645 to 5948 ng/mL. Samples containing > or = 500 ng/mL of amphetamine (the administrative cutoff for a positive result by gas chromatography-mass spectrometry) were seen up to 47:30 h post dose.
How do you convert ppm to Ng?
ng/g↔ppm 1 ppm = 1000 ng/g.
Is ppm the same as ng mL?
ppm↔ng/ml 1 ppm = 1000 ng/ml.
How do you convert ng uL to mg ml?
mg/mL↔ng/uL 1 mg/mL = 1000 ng/uL.
What is the cut off for morphine in a drug test?
(c) On a confirmation drug test, you must report a result below the cutoff concentration as negative and a result at or above the cutoff concentration as confirmed positive. (d) You must report quantitative values for morphine or codeine at 15,000 ng/mL or above.
What is the normal range for morphine and codeine levels?
Urinary morphine was between 155–1,408 (roll) and 294–4,213 ng/mL (raw), measured at 2, 4, 6 and 20 h post-ingestion. Urinary codeine concentrations between 140–194 (roll) and 121–664 ng/mL (raw) were observed up to 6 h post-ingestion.
What is the maximum concentration of morphine in a urine sample?
As an additional quality control step, this laboratory has run solutions with high concentrations of morphine (up to 25,000 ng/mL) to test whether hydromorphone may be formed as an artifact of the chromatography separation process. This was not found to be the case. The urine samples are frozen so that retesting is possible if requested.
Does hydromorphone increase morphine in urine?
Those with hydromorphone in their urine were on significantly greater amounts of morphine per day and displayed a significantly greater concentration of morphine in the urine. However, despite being on lower doses of morphine, women had significantly higher morphine urine concentrations (Table 2).
