The device description and performance studies describe a standard immunochromatographic assay (lateral flow test) which is read visually. There is no mention of any computational analysis, image processing, or algorithms that would suggest the use of AI/ML.
No.
This device is an in vitro diagnostic device used to detect Benzoylecgonine and Morphine in human urine. It is not designed to treat a disease or medical condition.
Yes
The document explicitly states multiple times that the device is "For in vitro diagnostic use only."
No
The device is described as an immunochromatographic assay in various physical formats (Strips, Cassettes, Dip Cards, Cups) and includes a test device, package insert, and urine cup. This clearly indicates it is a hardware-based in vitro diagnostic device, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The document explicitly states "For in vitro diagnostic use only." in the Intended Use/Indications for Use section for both the Cocaine and Morphine tests.
- Device Description: The Device Description section refers to the product as a "single-use in vitro diagnostic device".
- Intended Use: The intended use is for the qualitative determination of specific substances (Benzoylecgonine and Morphine) in human urine, which is a biological sample. This aligns with the definition of an in vitro diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic purposes.
- Testing Method: The device uses an immunochromatographic assay, which is a common method for in vitro diagnostic testing.
Therefore, based on the provided text, the Healgen COC One Step Cocaine Test and Healgen MOP One Step Morphine Test are clearly identified as in vitro diagnostic devices.

Intended Use / Indications for Use
Healgen COC One Step Cocaine Test is an immunochromatographic assay for the qualitative determination of Benzoylecgonine in human urine at a Cut-Off concentration of 300 ng/mL. The test is available in a Strip format, a Cassette format, a Dip Card format and a Cup format.
The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS is the preferred confirmatory method. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
For in vitro diagnostic use only. It is intended for over-the-counter and for prescription use.
Healgen MOP One Step Morphine Test is an immunochromatographic assay for the qualitative determination of morphine in human urine at a Cut-Off concentration of 300 ng/mL. The test is available in a Strip format, a Cassette format, a Dip Card format and a Cup format.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
-
Analytical Performance:
- Precision: Samples with concentrations of -100% cut-off, -50% cut-off, -25% cut-off, at the cut-off, +25% cut-off, +75% cut-off, and +100% cut-off were tested. Tests were performed two runs per day for 25 days.
- Linearity: Not applicable, as these are visually read devices.
- Stability: Devices are stable at 4-30 degree Celsius for 24 months based on accelerated and real-time stability studies.
- Cut-off: A total of 150 samples equally distributed at concentrations of -50% cut-off; -25% cut-off; cut-off; +25% cut-off; +50% cut-off were tested using three different lots of each device by three different operators. Results were all positive at and above +25% cut-off and all negative at and below -25% cut-off for both Cocaine and Morphine.
- Interference: Potential interfering substances found in human urine were added to drug-free urine and target drug urine at 25% above cut-off levels. These samples were tested using three batches of each device for all formats. No interference was observed for listed compounds at 100µg/mL.
- Specificity: Drug metabolites and other components were tested for cross-reactivity. Cocaethylene and Cocaine HCl showed 100% cross-reactivity for COC. 6-Acetylmorphine, Codeine, EthylMorphine, Heroin, Hydromorphone, Hydrocodone, Levorphanol, Oxycodone, Procaine, and Thebaine showed varying cross-reactivity for MOP.
- Effect of Urine Specific Gravity and Urine pH: Urine samples with specific gravity 1.000 to 1.035 or pH 4 to 9 were spiked with target drugs at 25% below and 25% above cut-off levels. All results were positive for samples at and above +25% cut-off and negative for samples at and below -25% cut-off.
-
Comparison Studies:
- Method Comparison: Performed in-house with three laboratory assistants for each format. 80 unaltered clinical samples (40 negative and 40 positive) were blind labeled and compared to GC/MS results.
- Lay-user study: Performed at three sites with 140 lay persons for cocaine devices and 140 for morphine devices. Participants had diverse backgrounds and ages (21 to >50 years). Urine samples were prepared at negative, +/-75%, +/-50%, +/-25% of the cutoff and confirmed by GC/MS. Each participant received a blind labeled sample and a device. Lay users also completed surveys on the ease of understanding instructions; all indicated ease of use. A Flesch-Kincaid reading analysis showed a Grade Level of 7 for package inserts.

9. Test Principle
Healgen COC One Step Cocaine Test and Healgen MOP One Step Morphine Test are rapid tests for the qualitative detection of Benzoylecgonine and Morphine in urine samples. Each assay test is a lateral flow chromatographic immunoassay. During testing, a urine specimen migrates upward by capillary action. If target drugs are present in the urine specimen below its cut-off concentration, it will not saturate the binding sites of its specific antibody (monoclonal mouse antibody) coated on the particles. The antibody-coated particles will then be captured by immobilized drug-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 target drug level exceeds its cutoff-concentration because it will saturate all the binding sites of the antibody coated on the particles. A band should form in the control region of the devices regardless of the presence of drug or metabolite in the sample.
10. Performance Characteristics

- a. Precision
Precision studies were carried out for samples with concentrations of -100% cut-off, -50% cut-off, -25% cut-off, at the cut-off, +25% cut-off, +75% cut-off, +75% cut-off and +100% cut-off. These samples were prepared by spiking drug in negative samples. Each drug concentration was confirmed by GC/MS. All sample aliquots were blinded labeled and randomized.

For each concentration, tests were performed two runs per day for 25 days. The results obtained are summarized in the following tables:

g. Effect of Urine Specific Gravity and Urine pH
To investigate the effect of urine specific gravity and urine pH, urine samples with of 1.000 to 1.035 specific gravity or urine samples with pH 4 to 9 were spiked with target drugs at 25% below and 25% above cut-off levels. These samples were tested using three batches of each device for all formats. Results were all positive for samples at and above +25% cut-off and all negative for samples at and below -25% Cut-Off. There were no differences observed for different formats. -

The method comparison studies for the One Step Cocaine Test, and the One Step Morphine Test were performed in-house with three different laboratory assistants for each format of the device. Operators ran 80 (40 negative and 40 positive) unaltered clinical samples were blind labeled and compared to GC/MS results. The results are presented in the tables below:

Lay-user study
A lay user study was performed at three intended user sites with 140 lay persons testing the cocaine devices and another set of 140 persons testing the morphine devices. A total of 56 females and 84 males tested the Cocaine samples, and 53 females and 87 males tested the Morphine samples. They had diverse educational and professional backgrounds and ranged in age from 21 to > 50 years. Urine samples were prepared at the following concentrations; negative, +/-75%, +/-50%, +/-25% of the cutoff by spiking drugs into drug free-pooled urine specimens. The concentrations of the samples were confirmed by GC/MS. Each sample was aliquoted into individual containers and blind-labeled. Each participant was provided with the package insert, 1 blind labeled sample and a device. The results are summarized below.
