The provided text is a 510(k) summary for the "Amedica Home Drug Test Cup," a device intended for over-the-counter (OTC) consumer use for detecting various drugs in human urine.
Acceptance Criteria and Device Performance:
The document does not explicitly state "acceptance criteria" in a table format with performance metrics. However, the core of the submission is to demonstrate substantial equivalence to legally marketed predicate devices, which implies that the performance of the Amedica Home Drug Test Cup is comparable to these predicates for the stated indications.
The key performance aspect mentioned is the detection of specific drugs at defined cutoff levels. The device is intended to provide a preliminary positive or negative result based on these cutoffs.
| Drug | Analyte | Cutoff | Reported Device Performance (Implied) |
|---|---|---|---|
| Marijuana | THC | 50 ng/mL | Detects THC at or above 50 ng/mL |
| Cocaine | Benzoecgonine | 300 ng/mL | Detects Benzoecgonine at or above 300 ng/mL |
| Amphetamine | Amphetamine | 1000 ng/mL | Detects Amphetamine at or above 1000 ng/mL |
| Methamphetamine | Methamphetamine | 1000 ng/mL | Detects Methamphetamine at or above 1000 ng/mL |
| Opiates | Morphine | 2000 ng/mL | Detects Morphine at or above 2000 ng/mL |
| Opiates300 | Morphine | 300 ng/mL | Detects Morphine at or above 300 ng/mL |
| Pencyclidine | Phencylidine | 25 ng/mL | Detects Phencylidine at or above 25 ng/mL |
| Barbiturates | Secobarbital | 300 ng/mL | Detects Secobarbital at or above 300 ng/mL |
| Benzodiazepines | Oxazepam | 300 ng/mL | Detects Oxazepam at or above 300 ng/mL |
| Methadone | Methadone | 300 ng/mL | Detects Methadone at or above 300 ng/mL |
| Oxycodone | Oxycodone | 100 ng/mL | Detects Oxycodone at or above 100 ng/mL |
| MDMA | MDMA | 500 ng/mL | Detects MDMA at or above 500 ng/mL |
| Tricyclic Antidepressants | Nortriptyline | 1000 ng/mL | Detects Nortriptyline at or above 1000 ng/mL |
Note: The document only lists the cutoffs and states the device's purpose is to detect these drugs at these cutoffs. It does not provide specific sensitivity, specificity, or accuracy data for the Amedica Home Drug Test Cup. The substantial equivalence claim implies that its performance is equivalent to legally marketed predicate devices, meaning it meets the generally accepted performance standards for point-of-care drug tests.
Study Information:
The provided text does not contain any details about a specific study (like a clinical trial or performance evaluation study) that proves the device meets acceptance criteria. A 510(k) submission primarily relies on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting full clinical trial data as would be required for a PMA (Premarket Approval) application.
Therefore, the following information points cannot be directly extracted from the provided text:
- Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not mentioned.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience): Not mentioned. The "ground truth" for these types of tests is typically established through a more specific alternate chemical method (like GC/MS or HPLC), not expert consensus in the diagnostic imaging sense.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not mentioned.
- If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not relevant or mentioned, as this is a device for drug detection and not an AI-assisted diagnostic imaging tool.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: The device itself is standalone in terms of generating a preliminary result. There's no "algorithm only" performance separate from the physical test cup.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): The document specifies that for preliminary positive results, a "more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas Chromatography / Mass Spectrometry (GC/MS) or High Performance Liquid Chromatography (HPLC) is the preferred confirmatory method." This indicates that GC/MS or HPLC are the established ground truth methods.
- The sample size for the training set: Not mentioned. This type of device relies on chemical reactions, not machine learning or AI with training sets.
- How the ground truth for the training set was established: Not applicable, as there's no training set in the AI/ML sense.
§ 862.3650 Opiate test system.
(a)
Identification. An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.(b)
Classification. Class II (special controls). An opiate test system is not exempt if it is intended for any use other than employment or insurance testing or is intended for Federal drug testing programs. The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing, and does not include devices intended for Federal drug testing programs (e.g., programs run by the Substance Abuse and Mental Health Services Administration (SAMHSA), the Department of Transportation (DOT), and the U.S. military).
