The Deepblue Multi-Drug Urine Test Cup is a rapid lateral flow immunoassay for the qualitative detection of 6-Monoacetylmorphine, d-Amphetamine, Benzoylecgonine, Buprenorphine, EDDP, fentanyl, Methadone, d-Methamphetamine, d/l-Methylenedioxymethamphetamine, Morphine, Nortriptyline, Oxazepam, Oxycodone, Phencyclidine, d-Propoxyphene, Secobarbital, and THC-COOH in human urine. The test cut-off concentrations and the compounds the tests are calibrated to are as follows:
| Test | Calibrator | Cut-off(ng/mL) |
|---|---|---|
| 6-MAM | 6-Monoacetylmorphine | 10 |
| AMP | d-Amphetamine | 500 or 1000 |
| BAR | Secobarbital | 300 |
| BUP | Buprenorphine | 10 |
| BZO | Oxazepam | 300 |
| COC | Benzoylecgonine | 150 or 300 |
| EDDP | 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrolidine | 300 |
| FYL | Fentanyl | 1 |
| MDMA | Methylenedioxymethamphetamine | 500 |
| MET | d-Methamphetamine | 500 or 1000 |
| MTD | d/l-Methadone | 300 |
| MOP/OPI | Morphine | 300 or 2000 |
| OXY | Oxycodone | 100 |

| PPX | d-Propoxyphene | 300 |
| TCA | Nortriptyline | 1000 |
| THC | 11-nor-Δ9-THC-COOH | 50 |
The single or multi-test cups can consist of up to seventeen (17) of the above listed analytes in any combination with or without on-board adulteration/specimen validity tests (SVT).
The tests provide only a preliminary result. A more specific alternative chemical method must be used to obtain a confirmed presumptive positive result. Gas Chromatography-Mass Spectrometry (GC-MS), Liquid Chromatography-Mass Spectrometry (LC-MS), and their tandem mass-spectrometer versions are the preferred confirmatory methods. Careful consideration and judgment should be applied to any drugs of abuse screen test result, particularly when evaluating preliminary positive results.
The Deepblue Home Multi-Drug Urine Test Cup is a rapid qualitative immunoassay. The device provides preliminary results for the detection of one or more of the following drugs.

|---|---|---|
| AMP | Amphetamine | 1000 or 500 |
| BUP | Buprenorphine | 10 |
| BAR | Secobarbital | 300 |
| BZO | Oxazepam | 300 |
| COC | Cocaine | 300 or 150 |
| EDDP | EDDP | 300 |
| FYL | Fentanyl | 1 |
| MET | Methamphetamine | 1000 or 500 |
| MDMA | Ecstasy | 500 |

This drug test cup may contain any combination of the drug tests listed in the table above.
This test provides only preliminary result. A more specific alternative chemical method must be used to obtain a confirmed presumptive positive result. Gas Chromatography-Mass Spectrometry (GC-MS), Liquid Chromatography-Mass Spectrometry (LC-MS), and their tandem mass-spectrometer versions are the preferred confirmatory methods.

Deepblue Home Muti-Drug Urine Test Cup and Deepblue Muti-Drug Urine Test Cup are immunochromatographic assays that use a lateral flow system for the qualitative detection of single or multiple drugs in human urine.
The device is a cup format. Each test device is sealed with two sachets of desiccant in an aluminum pouch. The device is in a ready-to-use format and no longer requires assembly before use.
The provided FDA 510(k) clearance letter details the performance characteristics of the Deepblue Multi-Drug Urine Test Cup and Deepblue Home Multi-Drug Urine Test Cup. This information allows us to describe the acceptance criteria and the study that proves the device meets these criteria.
It's important to note that this device is a qualitative lateral flow immunoassay for initial drug screening, not a diagnostic imaging AI, so the criteria and study methodology differ significantly from those for an AI-powered diagnostic tool. Specifically, there are no references to AI assistance, human readers, or image adjudication, as these are not relevant to this type of device.
Acceptance Criteria and Device Performance for Deepblue Multi-Drug Urine Test Cups
The acceptance criteria for this type of qualitative immunoassay are primarily based on its analytical performance, specifically its ability to correctly identify the presence or absence of target drugs at specified cutoff concentrations. This is demonstrated through precision/reproducibility studies, analytical specificity (cross-reactivity and interference), and method comparison studies against a gold standard (LC-MS/MS).
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are implicitly derived from the successful demonstration of performance in the analytical and method comparison studies. The goal is to achieve high agreement rates with the confirmatory method (LC-MS/MS) and consistent results at and around the cutoff concentrations.
| Performance Metric Category | Specific Acceptance Criteria (Implicit) | Reported Device Performance |
|---|---|---|
| Precision/Reproducibility | Consistent results across multiple lots and runs, especially at and near cutoff concentrations. High percentage of correct results for spiked samples at various concentrations. | Across three lots and 25 days of testing (50 runs per concentration), the device showed excellent performance. For concentrations at +50%, +75%, and +100% of cutoff, all results were positive (0-/50+). For concentrations at -50%, -75%, and -100% of cutoff, all results were negative (50-/0+). At the cutoff concentration, there was a mix of positive and negative results, indicating the assay's sensitivity at the threshold (e.g., AMP 1000: Lot 1 had 8-/42+, meaning 8 negatives and 42 positives out of 50 runs). Near the cutoff (e.g., -25% and +25%), expected mixed results were observed, demonstrating the assay's ability to differentiate. |
| Analytical Specificity (Cross-Reactivity) | Minimal cross-reactivity with non-target compounds and sufficient cross-reactivity with known metabolites/analogs to ensure broad detection. | Detailed tables provided showing specific cross-reactivity percentages for various compounds. For example, for AMP 1000, D,L-Amphetamine and D-Amphetamine showed 100% cross-reactivity as expected. For BAR 300, Alphenal showed 200% cross-reactivity, and Phenobarbital showed 150%. For FYL 1, Acetyl fentanyl showed 100%, and Butyryl Fentanyl showed 50%. Norfentanyl showed |
