COC

One Step

Cocaine Test Strip

Package Insert

 

A rapid, one step test for the qualitative detection of Cocaine Metabolite in human urine.

 

For healthcare professionals including professionals at point of care sites.

 

For in vitro diagnostic use only.

INTENDED USE

The COC One Step Cocaine Test Strip is a rapid chromatographic immunoassay for the qualitative detection of cocaine metabolite, Benzoylecgonine, in human urine at a cut-off concentration of 300 ng/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.

SUMMARY

 

Cocaine is a potent central nervous system (CNS) stimulant and a local anesthetic. Initially, it brings about extreme energy and restlessness while gradually resulting in tremors, over-sensitivity and spasms. In large amounts, cocaine causes fever, unresponsiveness, and difficulty in breathing and unconsciousness.

Cocaine is often self-administered by nasal inhalation, intravenous injection and free-base smoking. It is excreted in the urine in a short time primarily as Benzoylecgonine 1, 2. Benzoylecgonine, a major metabolite of cocaine, has a longer biological half-life (5 - 8 hours) than cocaine (0.5 - 1.5 hours), and can generally be detected for 24-48 hours after cocaine exposure.2

The COC One Step Cocaine Test Strip is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of cocaine metabolite in urine. The COC One Step Cocaine Test Strip yields a positive result when the cocaine metabolite in urine exceeds 300 ng/mL. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).

PRINCIPLE

The COC One Step Cocaine Test Strip is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody.

During testing, a urine specimen migrates upward by capillary action. Benzoylecgonine, if present in the urine specimen below 300 ng/mL, will not saturate the binding sites of antibody in the test strip. The antibody coated particles will then be captured by immobilized Benzoylecgonine conjugate and a visible colored line will appear in the test line region. The colored line will not form in the test line region if the Benzoylecgonine level exceeds 300 ng/mL because it will saturate all the binding sites of anti-Benzoylecgonine antibody.

A drug-positive urine specimen will not generate a colored line in the test line region because of drug competition, while a drug-negative urine specimen or a specimen containing a drug concentration less than the cut-off will generate a line in the test line region.

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.

REAGENTS

 

The test strip contains monoclonal anti-Benzoylecgonine antibody-coupled particles and Benzoylecgonine-protein conjugate. A goat antibody is employed in the control line system.

PRECAUTIONS

 

  • For healthcare professionals including professionals at point of care sites.
  • For professional in vitro diagnostic use only. Do not use after the expiration date.
  • The test strip should remain in the sealed pouch until use.
  • All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
  • Used test strip should be discarded according to federal, state and local regulations.

STORAGE AND STABILITY

 

Store as packaged in the sealed pouch at 2-30°C. The test strip is stable through the expiration date printed on the sealed pouch. The test strips must remain in the sealed pouch until use. DO NOT FREEZE. Do not use beyond the expiration date.

SPECIMEN COLLECTION AND PREPARATION

Urine Assay

The urine specimen must be collected in a clean and dry container. Urine collected at any time of the day may be used. Urine specimens exhibiting visible precipitates should be centrifuged, filtered, or allowed to settle to obtain a clear specimen for testing.

Specimen Storage

Urine specimens may be stored at 2-8ºC for up to 48 hours prior to testing. For prolonged storage, specimens may be frozen and stored below -20ºC. Frozen specimens should be thawed and mixed before testing.

MATERIALS

Materials Provided

  • Test strips
  • Package insert

 

Materials Required But Not Provided

  • Specimen collection container
  • Timer
  • External controls

DIRECTIONS FOR USE

Allow the test strip, urine specimen, and/or controls to equilibrate to room temperature (15-30ºC) prior to testing.

 

  • Bring the pouch to room temperature before opening it. Remove the test strip from the sealed pouch and use it as soon as possible.
  • With arrows pointing toward the urine specimen, immerse the test strip vertically in the urine specimen for at least 10-15 seconds. Do not pass the maximum line (MAX) on the test strip when immersing it. See the illustration below.
  • Place the test strip on a non-absorbent flat surface, start the timer and wait for the colored line(s) to appear. The result should be read at 5 minutes. Do not interpret the result after 10 minutes.

 

 

INTERPRETATION OF RESULTS

 

NEGATIVE:* Two lines appear. One colored line should be in the control region (C), and another colored line should be in the test region (T). This negative result indicates that the Benzoylecgonine concentration is below the detectable level (300 ng/mL).

* NOTE: The shade of the color in the test region (T) may vary, but it should be considered negative whenever there is even a faint line.

 

POSITIVE: One colored line appears in the control region (C). No line appears in the test region. This positive result indicates that the Benzoylecgonine concentration is above the detectable level (300 ng/mL).

 

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 with a new test strip. If the problem persists, discontinue using the test kit immediately and contact your local distributor.

QUALITY CONTROL

 

A procedural control is included in the test. A colored line appearing in the control region (C) is considered as 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 a good laboratory testing practice to confirm the test procedure and to verify proper test performance.

LIMITATIONS

 

  • The COC One Step Cocaine Test Strip provides only a qualitative, preliminary analytical result. A secondary analytical method must be used to obtain a confirmed result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method.3, 4
  • It is possible that technical or procedural errors, as well as other interfering substances in the urine specimen may cause erroneous results.
  • Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results regardless of the analytical method used. If adulteration is suspected, the test should be repeated with another urine specimen.
  • A Positive Result indicates presence of the drug or its metabolites but does not indicate level of intoxication, administration route or concentration in urine.
  • A Negative Result may not necessarily indicate drug-free urine. Negative results can be obtained when drug is present but below the cutoff level of the test.
  • Test does not distinguish between drugs of abuse and certain medications.

PERFORMANCE CHARACTERISTICS

 

Accuracy

A side-by-side comparison was conducted by laboratory personnel using the COC One Step Cocaine Test Strip and a commercially available rapid test. Testing was performed on specimens previously collected from subjects presenting for Drug Screen Testing. Presumptive positive results were confirmed by GC/MS. The following results were tabulated:

Method Other COC Rapid Test Total Results
COC One Step Test Strip Results Positive Negative
Positive 136 0 136
Negative 7 157 164
Total Results 143 157 300
% Agreement with this commercial kit 95% >99% 98%
 

 

When compared to GC/MS at the cut-off of 300 ng/mL, the following results were tabulated:

Method GC/MS Total Results
COC One Step Test Strip Results Positive Negative
Positive 119 17 136
Negative 5 159 164
Total Results 124 176 300
% Agreement with GC/MS Analysis 96% 90% 93%
 

 

 

Eighty (80) of these clinical samples were also run using the COC One Step Cocaine Test Strip by an untrained operator at a different site. Based on GC/MS data, the operator obtained a statistically similar Positive Agreement, Negative Agreement and Overall Agreement rate as the laboratory personnel.

 

Analytical Sensitivity

A drug-free urine pool was spiked with Benzoylecgonine at the following concentrations: 0 ng/mL, 150 ng/mL, 225 ng/mL, 300 ng/mL, 375 ng/mL and 450 ng/mL. The result demonstrates >99% accuracy at 50% above and 50% below the cut-off concentration. The data are summarized below:

 

 

Benzoylecgonine Concentration (ng/mL) Percent of Cutoff n Visual Result
Negative Positive
0 0 30 30 0
150 -50% 30 30 0
225 -25% 30 30 0
300 Cutoff 30 4 26
375 +25% 30 0 30
450 +50% 30 0 30

Precision

A study was conducted at three physician’s 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 were blind labeled and tested at each site. The results are given below:

 

Benzoylecgonine

ng/mL concentration

n Site 1 Site 2 Site 3
Pos. Neg. Pos. Neg. Pos. Neg.
0 15 0 14* 0 15 0 15
150 ng/mL 15 1 14 0 15 1 14
225 ng/mL 15 11 4 10 5 7 8
375 ng/mL 15 15 0 15 0 15 0
450 ng/mL 15 15 0 15 0 14 1
Non Valid 15 15/15 15/15 15/15
 

*Note: Non-valid results were obtained in this treatment. Non-valid tests were provided as part of this study to ensure that readers would accurately identify non-valid test results.

Effect of Urinary Specific Gravity

Fifteen (15) urine samples of normal, high, and low specific gravity ranges were spiked with 150 ng/mL and 450 ng/mL of Benzoylecgonine respectively. The COC One Step Cocaine Test Strip was tested in duplicate using the fifteen neat 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 Benzoylecgonine to 150 ng/mL and 450 ng/mL. The spiked, pH-adjusted urine was tested with the COC One Step Cocaine Test Strip in duplicate and interpreted according to the package insert. The results demonstrate that varying ranges of pH does not interfere with the performance of the test.

Cross-Reactivity

A study was conducted to determine the cross-reactivity of the test with compounds in either drug-negative urine or Benzoylecgonine positive urine. The following compounds show no interference when tested with the COC One Step Cocaine Test Strip at a concentration of 100 mg/mL.
