Intended Use

The Omega Laboratories Hair Drug Screening Assay for Cocaine and Cocaine Metabolites (Cocaine) is an in vitro diagnostic test that is intended for the qualitative detection of Cocaine at or above 500 pg/mg in human head and body hair. To confirm a screen positive result, a more specific alternate chemical method, such as Gas Chromatography/Mass Spectrometry (GC/MS) operating in the selected ion monitoring (SIM) mode is the preferred method with deuterated internal standards. Professional judgment should be applied to any drug of abuse test result, particularly when presumptive positive results are obtained. This test is intended exclusively for single laboratory use only and is not intended for sale to anyone.

AI/ML Overview

Here's a breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:

Acceptance Criteria and Device Performance for Omega Hair Drug Screening Assay for Cocaine and Cocaine Metabolites

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for substantial equivalence are demonstrated through various performance studies showing the device's agreement with a reference method (GC/MS) and its precision. Specific quantitative acceptance criteria for parameters like sensitivity, specificity, and accuracy are not explicitly stated with numerical targets, but the overall conclusion is based on "substantial agreement" and "acceptability."

Acceptance CriteriaReported Device Performance (Omega Assay vs. GC/MS or internal controls)
Precision (Intra-assay)11/11 correct results for all tested concentrations (negative, -75%, -50%, -25% below cutoff, and +25%, +50%, +75%, +100% above cutoff).
Precision (Inter-assay)220/220 correct results for all tested concentrations (negative, -75%, -50%, -25% below cutoff, and +25%, +50%, +75%, +100% above cutoff) over 20 non-consecutive runs. (Precision deemed acceptable if %CV < 15% - specific %CV values not provided, but overall results indicate acceptability).
Agreement with Reference Method (GC/MS)Out of 424 samples: - 122 GC/MS Negative (<50 pg/mg) correctly identified as Negative by ELISA. - 3 GC/MS Negative (<250 pg/mg) correctly identified as Negative by ELISA. - 34 GC/MS Negative (250-499 pg/mg) correctly identified as Negative by ELISA. - 24 GC/MS Positive (500-750 pg/mg) correctly identified as Positive by ELISA. - 210 GC/MS Positive (>750 pg/mg) correctly identified as Positive by ELISA. - 31 GC/MS Negative (250-499 pg/mg) identified as Positive by ELISA (discordant). (Specific sensitivity/specificity/accuracy metrics are not provided in percentage form, but raw counts are given.)
Cross-ReactivityStructurally similar compounds (Benzoylecgonine isopropyl ester, Cocaethylene, Cocaine, Benzoylecgonine, Meta-Hydroxybenzoylecgonine, Ecgonine, Norbenzoylecgonine, Norcocaine, Norcocaethylene, Ecgonine methyl ester, Anhydroecgonine methyl ester) demonstrated varying degrees of cross-reactivity. The report notes that these contributed to a positive ELISA result, but GC/MS confirmation would differentiate them.
Interfering CompoundsStructurally unrelated compounds did not interfere with the assay. Only structurally cross-reactive compounds produced a positive response. No expected positive samples produced a negative result.
Calibrator and Control ValidationSuccessfully demonstrated validation and stability of in-house prepared calibrator and control solutions, traceable to NIST standards.
Stability (Long-term storage)Mean variance in concentration of combined cocaine + metabolites was -23% over ~2 years. Largest decrease was -46%, largest increase was 17%. General trend of decreasing cocaine and increasing benzoylecgonine noted.
Shipping EffectsNo adverse effect on head hair samples and no discordant results (pre- and post-shipping) when exposed to extreme temperatures and humidity. Average percent change in positive cocaine GC/MS results was +5% for all locations combined.
Cosmetic Treatment EffectsDevice is not an exception to the phenomenon that cosmetic treatments can reduce drug amounts. Four initially positive ELISA assays reported negative after treatment (bleach or perm).
Environmental ContaminationAcknowledged that preliminary positive results could be due to environmental contamination, emphasizing the need for GC/MS confirmation to distinguish true positives.

2. Sample Sizes Used for the Test Set and Data Provenance

  • Test Set Sample Size: For the agreement study, 424 hair samples were used.
  • Data Provenance: The origin of the data (e.g., country of origin, retrospective or prospective) is not specified in the provided text. It only states that testing was performed on "body and head hair samples from different ages, gender, ethnicities and hair color."

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

  • Number of Experts: Not explicitly stated.
  • Qualifications of Experts: The ground truth for the agreement study was established using Gas Chromatography/Mass Spectrometry (GC/MS), which is a "more specific alternate chemical method" and "the preferred method with deuterated internal standards." This implies analysis by qualified laboratory personnel, but their specific number or qualifications (e.g., experience level) are not provided.

4. Adjudication Method for the Test Set

  • Adjudication Method: The text states, "Each specimen was divided into two aliquots and one was used for screening and the other for GC/MS confirmation." This indicates that any discrepancies between the ELISA screening and the GC/MS confirmation would be resolved by the GC/MS result, as it is considered the "reference method" and "preferred method." There is no explicit mention of a multi-reader adjudication panel (like 2+1 or 3+1). The GC/MS acts as the definitive adjudicator.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • Was it done?: No. This study evaluates an in vitro diagnostic test (ELISA assay), not a device that assists human readers in interpreting images or other data. Therefore, a multi-reader multi-case (MRMC) comparative effectiveness study with human readers assisting with AI vs. without AI assistance is not applicable to this type of device and was not performed.

6. Standalone Performance Study

  • Was it done?: Yes. The document presents standalone performance data for the ELISA assay against the GC/MS reference method. The "Agreement" section (Table 4a and 4b) directly compares the results of the Omega Laboratories Hair Drug Screening Assay (algorithm only, without human intervention in the interpretation of the assay result itself) to the GC/MS ground truth. The precision studies also represent standalone performance.

7. Type of Ground Truth Used

  • Type of Ground Truth: The primary ground truth used for the agreement study and for confirming screen positive results is Gas Chromatography/Mass Spectrometry (GC/MS) results, specifically mentioned as operating in the selected ion monitoring (SIM) mode with deuterated internal standards. This is a highly accurate and accepted analytical chemistry method for drug detection and quantification.

8. Sample Size for the Training Set

  • Training Set Sample Size: The document describes performance studies, but it does not provide information on a specific training set size for the development of the ELISA assay. This assay likely relies on established biochemical principles and reagent formulation rather than machine learning algorithms that typically require a distinct training set. The various "performance studies" described are for validation, not typically for training.

9. How the Ground Truth for the Training Set Was Established

  • Ground Truth for Training Set: As no explicit training set is described for this type of immunoassay, the concept of establishing ground truth for a training set in the context of an AI/ML algorithm is not applicable. The assay's development would involve optimizing antibody specificity and binding characteristics against known concentrations of cocaine and its metabolites, with the performance ultimately validated against a gold standard like GC/MS.

CROSSREACTIVITY: The Crossreactivity Study demonstrated that the presence of the structurally similar compounds Anhydroecgonine methyl ester, Benzoylecgonine isopropyl ester, Meta-Hydroxybenzoylecgonine, Cocaine, Cocaethylene, Ecgonine, Ecgonine methyl ester, Norbenzoylecgonine, Norcocaine, and Norcocaethylene may contribute to a Cocaine positive ELISA result when utilizing this protocol. Since a GC/MS confirmation is performed on all presumptive positive screening results, these compounds will not confirm as a positive result report. None of the other compounds studied demonstrated any interference with the protocol. Head hair was used in this study.

Although the percent cross-reactivity for Ecognine. Norcocaine. Norcocaine, Norcocaine, Norcocaethylene, Econine methyl ester and Anhydroecgonine methyl ester could be considered "low", they have been validated and are sufficiently high enough to produce a "positive" result at these testing concentrations. With the levels of cross-reactivity presented in the table above, these compounds demonstrate positive interference at -50%, +125% and +150% of the cut-off. To demonstrate that these drugs are sufficiently cross-reactive, the table below mathematically re-expresses the percent cross-reactivities as cocaine equivalent concentrations at -50% of the cut-off (250 pg/mg), using Anhydroecgonine methyl ester as an example. This was accomplished by multiplying the (Observed Cross-reactivity) by the (Tested Concentration pg/mg) and adding the 250 pg/mg cocaine present in the sample at -50% of the cut-off.

Example: Anhydroecgonine methyl ester spiked at 400,000 pg/mg into -50% of the cut-off cocaine control sample.

For this calculation we used 0.2% for the Anhydroecqonine methyl ester percent cross-reactivity.

(0.2/100) X (400,000 pg/mg tested concentration) = 800 pg/mg cocaine equivalents.

800 pg/mg cocaine equivalents + 250 pg/mg Cocaine present at -50% of the cutoff = 1050 pg/mg combined equivalent cocaine concentration.

This observed concentration is greater than the 500 pg/mg cocaine cutoff control. Similar calculations can be made for +125% and 150% of the cut-off.

Effect of Interfering Compounds: A variety of structurally related and unrelated compounds were tested for interference at 10000ng/ml (400000pd/mg) in the Omeda Laboratories, Inc. ELISA Cocaine Screening Protocol. Negative hair extracts were spiked with Cocaine at -50% (250pg/mg), +125% (625pd/mg) and +150% (750pg/mg) of the Cocaine Cutoff Concentration (500pg/mg). These were then additionally spiked with 10000ng/ml (40000pg/mg) of the structurally related compounds unless otherwise noted. The absorbances were compared to the 500 pg/mg Cocaine cutoff control (CO). Only those compounds that were structurally cross reactive interfered in the assay. These structurally related compounds produced a positive response due to significant cross-reactivity. Compounds tested that were not structurally cross-reactive did not interfere with the assay at any of the tested concentrations. No tested samples produced a negative result when expected to be positive. The analysis was performed in triplicate. Head hair was used for this study.

Table 5b: Interferences of Structurally Related and Unrelated Compounds on the Omega Laboratories. Inc. Cocaine ELISA Assay

CALIBRATOR AND CONTROL: The Omega Laboratories, Inc. ELISA Cocaine Screening Protocol utilizes in-house prepared calibrator and control solutions. This study successfully demonstrated the validation and stability of these solutions and the traceability to NIST standards.

While the typical urine drugs of abuse controls challenge the cutoff calibrator with concentrations of ± 25% of the cutoff calibrator in nanograms, the hair testing industry utilizes -50% and +100% in picograms. Example -25% of a nanogram is larger than -50% of a picogram. Head hair was used in this study.

STABILITY: The Stability Study demonstrated that the mean variance on the concentration of combined cocaine+ cocaine metabolites in 50 head hair samples when stored for an extended period of approximately 2 years was -23%.

Additionally, the largest decrease and increase for combined cocaine metabolites was -46% and 17%, respectively. The general trend of decreasing cocaine and increasing benzovlecgonine may be consistent with non-enzymatic hydrolysis of cocaine to benzoylecgonine. Head hair was used in this study.

SHIPPING: A total of 200 hair samples were use in the study; 100 positive samples and 100 negative samples. Head hair was used in this study.

The Shipping Study demonstrated that there was no adverse effect on head hair samples that would affect the screening assay when samples are exposed to extreme temperatures and variations in humidity that might occur during sample transport. The average percent change in Positive Cocaine sample GC/MS results prior to shipping and after shipping was +5% for all locations combined.

Additionally, there were no discordant results pre- and post-shipping (as confirmed by GC/MS).

COSMETIC TREATMENT: Numerous studies have demonstrated that the use of cosmetic treatments can reduce the amount of drugs and metabolites detected in hair specimens. This effect is completely dependent upon the nature of the hair specimen and the treatment used, and is independent of the method of analysis. This study demonstrates that the Omega Laboratories, Inc. ELISA Cocaine Screening Assay is not an exception to this phenomenon.

Sixty six hair specimens previously determined to be negative for cocaine were obtained and the ethnic origin, hair color and curvature were documented. One hundred and ten hair specimens potentially positive for cocaine were obtained and the ethnic origin, hair color and curvature were documented. Each specimen was divided into 2 aliquots. One aliquot was analyzed by the ELISA protocol and by the GC/MS confirmation method.

Of the 176 treated specimens, four initially POSITIVE ELISA assays (one bleach and three permanent) reported NEG ELISA results after treatment.

ENVIRONMENTAL CONTAMINATION: Preliminary positive hair sample results by the screening method could be due to environmental contamination. All positive samples should be sent for confirmation testing on a reference method to distinguish between true positives and those samples that were positive due to external exposure. Head hair was used for this study.

CONCLUSION:

The comparison of results of the proposed assay and GC/MS for Cocaine metabolites in head and body hair samples showed the results to be substantially equivalent

The candidate Omega Laboratories Hair Drug Screening Assay for Cocaine and Cocaine Metabolites is substantially equivalent to the predicate Omega Laboratories Hair Drug Screening Assay for Cocaine and
