Intended Use
The ACON BAR One Step Barbiturates Test Strip and ACON BAR One Step Barbiturates Test Device are rapid chromatographic immunoassays for the qualitative detection of barbiturates in urine at a cut-off concentration of 300 ng/mL. They are intended for use by healthcare professionals including professionals at point-of-care sites.
Device Description
The ACON BAR One Step Barbiturates Test Strip and ACON BAR One Step Barbiturates Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative screening of barbiturates in a urine sample. The test is based on the principle of antigen-antibody immunochemistry. It utilizes the antibody to selectively detect elevated levels of barbiturates in urine specimens at a designated cut-off concentration of 300 ng/mL. These tests can be performed without the use of an instrument. A drug-positive urine specimen will not generate a colored-line in the designated test region, while a negative urine specimen or a urine specimen containing barbiturates at the concentration below the cut-off level will generate a colored-line in the test region. To serve as a procedural control, a colored-line will always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
More Information

MCC Instant Screen Card BAR Test

No
The device description details a simple lateral flow immunoassay that provides a visual result based on antigen-antibody binding, with no mention of computational analysis or learning algorithms.

No
This device is for the detection of barbiturates in urine, which is a diagnostic purpose, not a therapeutic one. It does not provide treatment or ameliorate a condition.

Yes

This device is intended for the qualitative detection of barbiturates in urine, which is a diagnostic purpose, as it helps identify the presence of a specific substance in the body.

No

The device description clearly states it is a "rapid chromatographic immunoassay" and a "competitive binding, lateral flow immunochromatographic assay," which are physical test strips/devices, not software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is a "rapid chromatographic immunoassay for the qualitative detection of barbiturates in urine". This describes a test performed on a biological sample (urine) outside of the body to provide diagnostic information.
  • Device Description: The description details a "competitive binding, lateral flow immunochromatographic assay for the qualitative screening of barbiturates in a urine sample." This further confirms it's a test performed on a biological specimen.
  • Performance Studies: The document describes a clinical evaluation using "clinical urine specimens" and comparing the results to other tests and a reference method (GC/MS). This is typical for the validation of an IVD.
  • Predicate Device: The mention of a "Predicate Device" (K002337; MCC Instant Screen Card BAR Test) which is also an IVD, strongly indicates that this device falls into the same category.

All of these points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnostic, monitoring, or compatibility purposes.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

A clinical evaluation was conducted using 292 clinical urine specimens including 10% of the samples with barbiturate concentrations at -25% cut-off to +25% cut-off range. This evaluation compared the test results between ACON® BAR One Step Barbiturates Test Strip and Test Device with MCC Instant Screen Card BAR Test; as well as against data obtained from the customary Gas Chromatography/Mass Spectrometry analysis. The comparisons of data obtained from this study yielded the following results:

§ 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).
