The device description and performance studies describe a standard enzyme immunoassay, which does not involve AI or ML. There are no mentions of AI, DNN, or ML in the provided text.
No
The description explicitly states "Measurements obtained by this device are used in the diagnosis and treatment of barbiturates use or overdose." Additionally, the "Device Description" section states that "Barbiturates is an in vitro diagnostic assay", indicating it is used for diagnostic purposes, not therapeutic treatment.
Yes.
The "Intended Use / Indications for Use" section explicitly states, "Measurements obtained by this device are used in the diagnosis and treatment of barbiturates use or overdose."
No
The device is an in vitro diagnostic assay, which is a chemical test performed on biological samples. This inherently involves physical reagents and laboratory equipment, not just software.
Based on the provided text, the device is indeed an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The text explicitly states the assay is "used for the qualitative analysis of barbiturates in human urine... for use in clinical laboratories." It also mentions the measurements are "used in the diagnosis and treatment of barbiturates use or overdose." These are all hallmarks of an IVD device.
- Device Description: The description begins by stating, "Barbiturates is an in vitro diagnostic assay..." This is a direct declaration of its IVD status.
- Anatomical Site: The analysis is performed on "human urine," which is a biological specimen collected from the human body, a common characteristic of IVDs.
- Intended User/Care Setting: The device is intended for use in "clinical laboratories," which are the typical settings for performing IVD tests.
- Predicate Device(s): The mention of a predicate device (K902580; Emit® II Barbiturate assay) is common in regulatory submissions for IVDs, indicating a comparison to an already cleared IVD device.
Therefore, all the provided information strongly supports the conclusion that this device is an IVD.
N/A
Intended Use / Indications for Use
The Barbiturates assay is used for the qualitative analysis of barbiturates in human urine with a cutoff of 200 ng/mL for use in clinical laboratories. Measurements obtained by this device are used in the diagnosis and treatment of barbiturates use or overdose.
The Barbiturates assay is calibrated with secobarbital and will detect a variety of Barbiturates.
The Barbiturates 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.

Device Description
Barbiturates is an in vitro diagnostic assay for the qualitative analysis of barbiturates in human urine. The assay is a homogeneous enzyme immunoassay with a 200 ng/mL cutoff. The assay is based on competition between drug in the specimen and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for antibody binding sites. Enzyme activity decreases upon binding to the antibody, so the drug concentration in the specimen can be measured in terms of enzyme activity. Active enzyme converts NAD to NADH, resulting in an absorbance change that can be measured spectrophotometrically.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative performance studies were conducted using the AEROSET® System. The Barbiturates assay method comparison yielded acceptable correlation with the Emit II Barbiturate assay on the SYVA-30R Analyzer. The concordance table for the Barbiturates assay shows 96% agreement. Six samples were negative using the Emit II Barbiturate assay on the SYVA-30R Analyzer and positive using the Barbiturates assay. These samples were shown to contain 829, 898, 661, 998, 1,048 and 969 ng/ml. of phenobarbital as determined by GC/MS. The Barbiturates assay method comparison yicl(led acceptable correlation with GC/MS. The concordance table for the Barbiturates assay shows 100% agreement with GC/MS. The clinical specimens tested ranged from 302 to 6,481 ng/mL. Precision studies were conducted using the Barbiturates assay. A within-run and total precision study was performed using five levels of control material. The total %CV for Verifier I is 0.47%. The total %CV for the Cutoff Calibrator is 0.53%. The total %CV for Verifier II is 0.55%. The total %CV for the - 25% Control of Cutoff Calibrator and the + 25% Control of Cutoff Calibrator samples are 0.61% and 0.55%, respectively. The Barbiturates assay cutoff is 200 ng/mL. The limit of detection (sensitivity) of the Barbiturates assay is 20 ng/mL. These data demonstrate that the performance of the Barbiturates assay is substantially equivalent to the performance of the Emit II Barbiturate assay on the SYVA 30R Analyzer.

§ 862.3150 Barbiturate test system.
(a)
Identification. A barbiturate test system is a device intended to measure barbiturates, a class of hypnotic and sedative drugs, in serum, urine, and gastric contents. Measurements obtained by this device are used in the diagnosis and treatment of barbiturate use or overdose and in monitoring levels of barbiturate to ensure appropriate therapy.(b)
Classification. Class II (special controls). A barbiturate 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).
