Intended Use

The CEDIA® Opiate OFT Assay is intended for use in the qualitative determination of opiates at a cutoff of 30.0 ng/mL in neat oral fluid. The specimen must be collected exclusively with the Oral-Eze™ Saliva Collection System. The assay is calibrated against morphine and performed on the MGC 240. This in vitro diagnostic device is intended for clinical laboratory use only. The CEDIA Opiate OFT Assay provides only a preliminary analytical test result. A more specific alternative method must be used to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry (GC/MS) and Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) are the preferred confirmatory methods. Clinical consideration and professional judgment should be applied to any drug of abuse test result particularly when preliminary positive results are used.

Device Story

The CEDIA® Opiate OFT Assay is a homogeneous enzyme immunoassay for detecting opiates in oral fluid. Input consists of oral fluid collected via the Oral-Eze™ Saliva Collection System. The assay utilizes recombinant DNA technology involving two inactive fragments of the bacterial enzyme β-galactosidase. In the presence of opiates, the drug competes with enzyme-donor-conjugated drug for antibody binding sites; this allows the inactive enzyme fragments to re-associate into an active enzyme. The active enzyme cleaves a substrate, producing a color change measured spectrophotometrically. The absorbance change is directly proportional to the opiate concentration. The assay is performed on the MGC240 analyzer in a clinical laboratory setting by trained personnel. Results are preliminary and require confirmation by GC/MS or LC-MS/MS. The device aids clinicians in identifying potential opiate use, supporting clinical decision-making when combined with professional judgment.

Clinical Evidence

Bench testing only. Precision evaluated per CLSI EP5-A2; 100% concordance at cutoff +/- 75%. Method comparison studies (n=82 and n=42) against GC/MS and LC-MS/MS showed 97.6% overall concordance. Analytical specificity and interference testing (endogenous/exogenous substances, pH, food/dental products) confirmed no significant interference at +/- 50% of cutoff.

Technological Characteristics

Homogeneous enzyme immunoassay using recombinant DNA-derived β-galactosidase fragments. Operates via competitive binding principle. Calibrated against morphine. Performed on MGC240 analyzer. Sample matrix: oral fluid collected via Oral-Eze™ Saliva Collection System (absorbent pad with volume adequacy indicator). Spectrophotometric detection.

Indications for Use

Indicated for qualitative determination of opiates in neat oral fluid at 30.0 ng/mL cutoff. For clinical laboratory use only; prescription use only. Not for point-of-care settings.

Regulatory Classification

Identification

An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.

Special Controls

*Classification.* Class II (special controls). An opiate 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).

# Legally marketed device to which equivalency is claimed

## DESCRIPTION OF DEVICE

# Principle of the CEDIA® Opiate OFT Assay

Microgenics CEDIA® Opiate OFT Assay uses recombinant DNA technology to produce a unique homogeneous enzyme immunoassay system. The assay is based on the bacterial enzyme ß-galactosidase, which has been genetically engineered into two inactive fragments. These fragments spontaneously re-associate to form fully active enzyme that, in the assay format, cleave a substrate, generating a color change that can be measured spectrophotometrically.

In the assay, analyte in the sample competes with analyte conjugated to one inactive fragment (enzyme donor) of β-galactosidase for antibody binding site. If analyte is praesent in the sample, it binds to antibody, leaving the inactive enzyment free to form active enzyme. If the analyte is not present in the sample, antibody binds to analyte conijugated on the inactive fragment, inhibiting the re-association of inactive B-galectosidase fragments, and no active enzyme is formed. The amount of active enzyme formed and fightently, absorbance change are directly proportional to the amount of analyte present it the sample.

## Principle of Oral-Eze™ Saliva Collection System

The Oral-Eze™ Saliva Collection System consists of Oral-Eze™ saliva collector and collection tube with preservative buffer. Oral-Eze™ saliva collector consists of an absorbent pad attached to a plastic handle. The saliva collector is provided with a volume adecruacy indicator. The plastic handle has a round window where blue color will appear when sufficient volume of oral fluid is collected. Samples are collected by placing the collector pad and plastic shield between lower cheek and gum with the plastic shield facing the cheek. Oral fluid collection is done when blue color appears in the window of the handle. The pad is ejected in to the collection tube by placing thumb on the ridges on the handle and pushing the thumb forward. The collection tube is capped and sent to the laboratory for processing and testing.
