Intended Use
The Visualine® Barbiturates DipStrip Test is used for qualitative testing for the presence of Secobarbital in urine samples at or above 300 ng/ml. This test provides only a preliminary screening result; a more specific alternative method should be used to confirm the test result. This test is intended for use by medical professionals.
Device Description
The Visualine® Barbiturates DipStripTest is based on the principle of antigen-antibody complexation and is used for the analysis of Barbiturates and it's metabolites in urine samples. The assay utilizes a competitive immunochromatographic technique involving a sample of test urine delivered in a sample well on the device that holds the porous membrane. When the drug is present in the urine test sample, the drug or drug metabolite competes for the limited antibody sites on the colored microspheres. When an adequate amount of drug is present, it will fill the limited antibody binding sites. This will prevent attachment of the colored microspheres to the probe site on the membrane. Therefore, a positive urine sample will inhibit the formation of precipitin at the probe site. A reference or control line with a secondary antibody reaction is added to the membrane strip to indicate viability of the test. This control line should always be present. A negative urine sample will produce two colored lines and a positive urine sample will show only one, the control line.

No
The device description details a standard immunochromatographic assay based on antigen-antibody reactions, with no mention of AI or ML technology. The performance studies are based on correlation with a predicate device, not on training or testing AI/ML models.

No.
The device is a diagnostic test used to detect the presence of Secobarbital in urine, not to treat or alleviate a medical condition.

Yes
Explanation: The device is used for qualitative testing for the presence of Secobarbital in urine samples, providing a preliminary screening result for medical professionals, which is a diagnostic function.

No

The device description clearly outlines a physical dipstrip test based on immunochromatographic principles, involving a porous membrane, colored microspheres, and antibody reactions. This indicates a hardware-based diagnostic test, not a software-only device.

Based on the provided information, the Visualine® Barbiturates DipStrip Test is an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use explicitly states it's for "qualitative testing for the presence of Secobarbital in urine samples". This involves testing a sample taken from the human body (urine) in vitro (outside the body) to provide information about a physiological state (presence of a drug).
  • Device Description: The description details a test based on "antigen-antibody complexation" and "immunochromatographic technique" applied to "urine samples". This is a common methodology for IVD tests.
  • Intended User / Care Setting: It is intended for "professional use only" and "medical professionals", which aligns with the typical use of IVD devices in a healthcare setting.
  • Performance Studies: The document describes correlation studies with a "Hitachi Barbiturates Assay", which is likely another IVD device, further indicating that the Visualine® test is also in this category.

The definition of an IVD device generally includes reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. While this specific test is for drug screening, drug screening tests performed on samples from the human body are considered a type of IVD.

Correlation studies between Hitachi Barbiturates Assay and Visualine® Barbiturates DipStrip Test were conducted at Sun Biomedical Laboratories with samples provided by The Lab, Inc.

Summary of Performance Studies

Correlation studies between Hitachi Barbiturates Assay and Visualine® Barbiturates DipStrip Test were conducted at Sun Biomedical Laboratories with samples provided by The Lab, Inc. Correlation with Hitachi EmitII® Barbiturates Assay with cutoff at or above 300 ng/ml Barbiturates yielded the following data:

  • Sensitivity: 95 / 101 = 94 %
  • Specificity: 95 / 100 = 95 %
  • Efficiency: 190 / 201 = 95 %

The test is specific to Barbiturates or structurally related compounds. The test detects Barbiturates at a concentration of 300 ng/ml. The sensitivity at 360 ng/ml Barbiturates read at 5 minutes is 94%. Reproducibility studies indicate: Within run and run to run > 99 %, Within day and day to day > 99 %, Within lot and lot to lot > 99 %. The Visualine® Barbiturates DipStrip Tests detect barbiturates at a cutoff of 300 ng/ml.

§ 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).
