Device Story
The Forsure Rapid One Step Multiple(X) Abuse Drug Screen Test Cup Device is a lateral flow chromatographic immunoassay for the qualitative detection of drugs of abuse in human urine. The device consists of absorbent strips containing immobilized drug conjugates and colloidal gold-labeled antibodies. As urine wicks through the membrane, drug metabolites in the sample compete with immobilized antigens for antibody binding sites. A negative result is indicated by the presence of two magenta bands (test and control zones), while a positive result is indicated by a single band in the control zone. The device is intended for use by medical professionals in clinical settings for rapid screening. Results are visual and qualitative; no instrumentation is required. The test provides preliminary results that must be confirmed by GC/MS. The device aids clinical decision-making by identifying potential substance use, allowing for subsequent confirmatory testing.
Clinical Evidence
No clinical studies performed. Analytical performance established via bench testing. Precision/reproducibility evaluated using drug-spiked urine at 0, 50%, 75%, 100%, 125%, and 150% of cutoff.

L. Test Principle:
The Forsure Rapid One Step Multiple (X) Abuse Drug Screen Test Cup Device and holder are designed to hold one or up to twelve individual chromatographic absorbent strips in which the drug or drug metabolites in the sample compete with a drug conjugate immobilized on a porous membrane support for the limited antibody sites. As the sample flows through the absorbent device by chromatography, the labeled antibody-Gold sol conjugate binds to the free drug in the sample forming an antibody-antigen complex. This complex competes with immobilized antigen conjugate in the test zone. If the concentration of drug is above the cutoff concentration no magenta colored band will form, indicating a positive result. If the concentration of drug in the sample is below the cutoff, a magenta colored band will form, indicating a negative result. Unbound dye conjugate binds to the reagent in the control zone, producing a magenta colored band, regardless of the presence or absence of drug or drug metabolite in the urine sample.

Specific Gravity:
Two drug free urines, one with a specific gravity of 1.030 and the other 1.003. The sample was divided into two and one was spiked with drug concentration at 25% above the cutoff for all the analytes. Each sample was run in duplicate. The results demonstrate that a specific gravity range of 1.003 - 1.030 did not affect the expected or accuracy of the results.
pH:
The pH of an aliquot negative urine pool was adjusted to a pH range of 4 to 9 in 1 pH increments for a total of six samples. Each of the samples was split into two samples to form a pair for each pH level. One of the paired samples from each set was spiked with drug concentration at 25% above the cutoff for all the analytes. Each sample was run on the device and the results demonstrate that varying ranges of pH dose not interfere with the performance of the test.

f. Assay cut-off:
The identified cutoff concentrations for amphetamine, cocaine, methamphetamine, opiates 2000, Phencyclidine and THC are those recommended by the Substance Abuse and Mental Health Services Administration (SAMHSA). The SAMHSA has not recommended a cutoff concentration for Barbiturate, Benzodiazepine, Oxycodone, Propoxyphene and Tricyclic Antidepressant (TCA).
Characterization of how the device performs analytically around the claimed cutoff concentration appears in the precision and detection limit sections, above.
2. Comparison studies:
a. Method comparison with predicate device:
83-110 urine samples, depending on the drug type were evaluated. Specimens obtained from a reference laboratory were tested using the Forsure Rapid One Step Multiple (X) Abuse Drug Screen Test Cup Device and the Gas Chromatography/Mass Spectrometry (GC/MS). For each tested, approximately 10% of samples had drug concentration between 50% below the cutoff and the cutoff concentration, another 10% of samples had drug concentration between the cutoff and 50% above the cutoff concentration.

During the accuracy for Amphetamine and Methamphetamine testing one discordant result was observed. A sample was run for both analytes, during the Amphetamine testing the PCP was recorded as positive and in the Methamphetamine the PCP was recorded as negative. The results were not confirmed by a reference method.
During the accuracy of the other analytes there were positive results recorded for analytes other than the one being tested. None of the other results were confirmed by a reference method.
