Intended Use
The Accu-Stat™ Home Drug Test for Marijuana (THC) is a screening test for the rapid detection of THC and its metabolites in human urine at a cut-off level of 50 ng/ml. The test is intended for over-the-counter (OTC) consumer use as the first step in a two step process to provide consumers with information concerning the presence or absence of THC or its metabolites in a urine sample. Information, along with the materials for shipping a portion of the urine specimen to the laboratory for confirmation testing of a preliminary positive result, the second step in the process, is provided. The Accu-Stat™ Home Drug Tcst for Marijuana and Cocaine (THC, COC) is a screening test for the rapid detection of THC and/or COC and its metabolites in human urine at a cut-off level of 50 ng/ml for THC and 300 ng/ml for COC. The test is intended for over-the-counter (OTC) consumer use as the first step in a two step process to provide consumers with information concerning the presence or absence of either THC, COC (or their metabolites) in a urine sample. Information, along with the materials for shipping a portion of the urine specimen to the laboratory for confirmation testing of a preliminary positive result, the second step in the process, is provided.
Device Description
The Accu-Stat™ Home Drug Test for Marijuana (THC) and the Accu-Stat™ Home Drug Test for Marijuana & Cocaine (THC, COC), like other commercially available drug screening tests, qualitatively measures the presence or absence of THC and COC and their metabolites in urine, using a one step, rapid chromatographic immunoassay which operates under the principle of competitive binding. Drugs, which may be present in the urine specimen, compete against the drug conjugate for binding sites on the antibody. During testing, a urine specimen migrates upward by capillary action. Marijuana, if present in the urine specimen below 50 ng/ml, and Cocaine, if present in the urine specimen below 300 ng/ml, will not saturate the binding sites of the antibody coated particles in the test device. The antibody coated particles will then be captured by immobilized marijuana or cocaine conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the marijuana level is above 50 ng/ml because it will saturate all the binding sites of anti-marijuana antibodies. The same holds true for cocaine if the level is above 300 ng/ml. It will saturate all the binding sites of anti-cocaine antibodies and therefore the colored line will not form in the test region. A drug-positive urine specimen will not generate a colored line in the test line region because of drug competition, while a drug-negative urine specimen will generate a line in the test region because of the absence of a drug competition. To serve as a procedural control, a colored line will always appear at the control line region if the test has been performed properly.
More Information

No
The device description details a rapid chromatographic immunoassay based on competitive binding, which is a standard chemical detection method and does not involve AI or ML. The summary does not mention any computational analysis or algorithms beyond the chemical reaction itself.

No.
The device is a screening test for rapid detection of drugs in urine and does not treat or alleviate a medical condition or disease.

Yes
The device is described as a "screening test for the rapid detection of THC and its metabolites in human urine," which provides "information concerning the presence or absence of THC or its metabolites." This falls under the definition of a diagnostic device as it aims to identify or detect a particular condition or substance.

No

The device description clearly describes a physical immunoassay test strip that uses capillary action and competitive binding to detect substances in urine. This involves hardware components and chemical reactions, not just software.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is a "screening test for the rapid detection of THC and its metabolites in human urine" and "for the rapid detection of THC and/or COC and its metabolites in human urine." This involves testing a biological specimen (urine) in vitro (outside the body) to gain information about a person's health status (presence of drugs).
  • Device Description: The description details a "rapid chromatographic immunoassay" that "qualitatively measures the presence or absence of THC and COC and their metabolites in urine." This is a common method used in IVD tests.
  • Specimen Type: The test uses "human urine," which is a biological specimen.
  • Purpose: The purpose is to provide "information concerning the presence or absence of THC or its metabolites in a urine sample" and "information concerning the presence or absence of either THC, COC (or their metabolites) in a urine sample." This information is used for screening purposes related to drug use.

The fact that it's intended for over-the-counter (OTC) consumer use and is the first step in a two-step process (with laboratory confirmation for positive results) does not change its classification as an IVD. It is still performing a diagnostic test on a biological sample in vitro.

  • Discussion of Technological Characteristics: The Accu-Stat™ Home Drug VIII. Test for Marijuana (THC) and the Accu-Stat™ Home Drug Test for Marijuana & Cocaine (THC, COC), like other commercially available drug screening tests, qualitatively measures the presence or absence of THC and COC and their metabolites in urine, using a one step, rapid chromatographic immunoassay which operates under the principle of competitive binding. Drugs, which may be present in the urine specimen, compete against the drug conjugate for binding sites on the antibody. During testing, a urine specimen migrates upward by capillary action. Marijuana, if present in the urine specimen below 50 ng/ml, and Cocaine, if present in the urine specimen below 300 ng/ml, will not saturate the binding sites of the antibody coated particles in the test device. The antibody coated particles will then be captured by immobilized marijuana or cocaine conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the marijuana level is above 50 ng/ml because it will saturate all the binding sites of anti-marijuana antibodies. The same holds true for cocaine if the level is above 300 ng/ml. It will saturate all the binding sites of anti-cocaine antibodies and therefore the colored line will not form in the test region.
    A drug-positive urine specimen will not generate a colored line in the test line region because of drug competition, while a drug-negative urine specimen will generate a line in the test region because of the absence of a drug competition. To serve as a procedural control, a colored line will always appear at the control line region if the test has been performed properly.

Examples of predicate devices include the First Check® Home Drug Tests and the Phamatech At Home Drug Tests using a single or multi-drug display. The consumer studies using the Accu-Stat™ Home Drug Test for Marijuana (THC) and the Accu-Stat™ Home Drug Test for Marijuana & Cocaine (THC, COC) demonstrates that the test exhibits excellent overall performance in the hands of lay users. The data supports the conclusion that the consumer can use the Accu-Stat™ Home Drug Tests to obtain immediate, preliminary information regarding the possible use of THC and COC.

  • IX. Safety and Effectiveness: Because the Accu-Stat™ Home Drug Test for Marijuana (THC) and the Accu-Stat™ Home Drug Test for Marijuana & Cocaine (THC, COC) are identical to the ACON Laboratories One Step Marijuana Test Device and the Multi-Drug Multi-Line Device that is legally marketed under K003557 and K020313 respectively for professional use, and because no special skills, training, education, or licensing is required to transfer a few drops of a urine sample into the test card well, there is no issue regarding the safety or effectiveness of the product to perform its intended function, i.e., to screen urine for the presence or absence of THC or THC & COC and its/their metabolite(s). Because the labeling of the Accu-Stat™

Home Drug Test for Marijuana (THC) and the Accu-Stat™ Home Drug Test for Marijuana & Cocaine (THC, COC) is substantially equivalent to a variety of rapid screening tests currently in commercial distribution, including the First Check® Home Drug Test and the Phamatech At Home™ Drug Test, and there have been no reports of consumer inability to follow instructions or interpret results over the many months these products have been purchased, it should be concluded that the product can be used effectively by the lay user.
