One-Step Morphine Test Cassette
Package insert for Morphine Test Cassette.
This Instruction Sheet is for testing of Morphine.
For professional and in vitro diagnostic use only.
The MOP One-Step Morphine Test Cassette is a lateral flow chromatographic immunoassay for the qualitative detection of Morphine in urine at the following cut-off concentration of 300ng/ml.
This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
Opiate refers to any drug that is derived from the opium poppy, including the natural products, morphine and codeine, and the semi-synthetic drugs such as heroin. Opioid is more general, referring to any drug that acts on the opioid receptor.
Opioid analgesics comprise a large group of substance which control pain by depressing the central nervous system. Large doses of morphine can produce higher tolerance level and physiological dependency in users, and may lead to substance abuse. Morphine is excreted unmetabolized, and is also the major metabolic product of codeine and heroin. Morphine is detectable in the urine for several days after an opiate dose.
The MOP One-Step Morphine Test Cassette yields a positive result when the concentration of morphine in urine exceeds 300ng/ml.
The MOP One-Step Morphine Test Cassette is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against their respective drug conjugate for binding sites on their specific antibody.
During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible colored line will show up in the test line region of the specific drug cassette. The presence of drug above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the colored line will not form in the test line region.
A drug-positive urine specimen will not generate a colored line in the specific test line region of the cassette because of drug competition, while a drug-negative urine specimen will generate a line in the test line region because of the absence of drug competition.
To serve as a procedural control, a colored line will always appear at the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
|Warnings and Precautions|
The test contains a membrane strip coated with drug-protein conjugates on the test line, a goat-anti-mouse IgG polyclonal antibody on the control line, and a dye pad which contains colloidal gold-monoclonal antibody specific to Morphine.
Each box contains test panels and package insert.
|Storage and Stability|
|Additional Special Equipment|
ŸSpecimen collection containerŸTimerŸExternal controls
Allow the test and urine samples to equilibrate to room temperature (15-30℃or 59-86℉) prior to testing.
|Interpretation of Results|
Negative:*Two lines appear. One red line should be in the control region (C), and another apparent red or pink line adjacent should be in the test region (T). This negative result indicates that the drug concentration is below the detectable level.
*NOTE: The shade of red in the test line region (T) will vary, but it should be considered negative whenever there is even a faint pink line.
Positive: One red line appears in the control region (C). No line appears in the test region (T). This positive result indicates that the drug concentration is above the detectable level.
Invalid: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test using a new test panel. If the problem persists, discontinue using the lot immediately and contact your local distributor.
A procedural control is included in the test. A red line appearing in the control region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
Control standards are not supplied with this kit. However, it is recommended that positive and negative controls be tested as good laboratory practice to confirm the test procedure and to verify proper test performance.
A side-by-side comparison was conducted using the MOP One-Step Morphine Test Cassette and commercially available drug rapid tests. Testing was performed on approximately 300 specimens per drug type previously collected from subjects presenting for Drug Screen Testing. Presumptive positive results were confirmed by GC/MS. The following compounds were quantified by GC/MS and contributed to the total amount of drugs found in presumptive positive urine samples tested.
|Test||Compounds Contributed to the Totals of GC/MS|
The following results are tabulated from these clinical studies:
|%Agreement with Commercial Kit||%Agreement with GC/MS|
Forty (40) clinical samples for each drug were run using the MOP One-Step Morphine Test Cassette by an untrained operator at a Professional Point of Care site. Based on GC/MS data, the operator obtained statistically similar Positive Agreement, Negative Agreement and Overall Agreement rates as trained Laboratory personnel.
A study was conducted at three physician offices by untrained operators using three different lots of product to demonstrate the within run, between run and between operator precision. An identical panel of coded specimens, containing drugs at the concentration of ± 50% and ± 25% cut-off level, was labeled as a blind and tested at each site. The results are given below:
|n per site||Site A||Site B||Site C|
A drug-free urine pool was spiked with drugs at concentrations listed. The results are summarized below.
The following table lists the concentration of compounds (ng/ml) that are detected positive in urine by the MOP One-Step Morphine Test Cassette at 3-5 minutes.
|Morphine (MOP 300)||Concentration (ng/ml)|
|Effect of Urinary Specific Gravity|
Fifteen (15) urine samples of normal, high, and low specific gravity ranges (1.000-1.037) were spiked with drugs at 50% below and 50% above cut-off levels respectively. The MOP One-Step Morphine Test Cassette was tested in duplicate using fifteen drug-free urine and spiked urine samples. The results demonstrate that varying ranges of urinary specific gravity does not affect the test results.
|Effect of the Urinary pH|
The pH of an aliquoted negative urine pool was adjusted to a pH range of 5 to 9 in 1 pH unit increments and spiked with drugs at 50% below and 50% above cut-off levels. The spiked, pH-adjusted urine was tested with the MOP One-Step Morphine Test Cassette. The results demonstrate that varying ranges of pH does not interfere with the performance of the test.
A study was conducted to determine the cross-reactivity of the test with compounds in either drug-free urine or Morphine positive urine. The following compounds show no cross-reactivity when tested with the MOP One-Step Morphine Test Cassette at a concentration of 100µg/ml.
|Non Cross-Reacting Compounds|
|Diphenhydramine||Ecgonine methyl ester|
|[1R,2S] (-) Ephedrine||L(–)-Epinephrine|
|Tetrahydrozoline||Tetrahydrocortisone 3 (β-D-glucuronide)|
*Parent compound only; metabolizes amphetamine and methamphetamine in urine.
