Device Story
The RapidFRET Oral Fluid Assay for PCP is a homogeneous time-resolved fluorescence immunoassay used for qualitative drug screening. It utilizes the RapidEASE Oral Fluid Collector to obtain neat oral fluid samples. The assay operates on the RapidFRET Integrated Workstation, which automates all pipetting and reading steps. The principle of operation is a competitive immunoassay based on Fluorescence Resonance Energy Transfer (FRET); drug in the sample competes with donor-fluorophore-labeled drug for binding sites on an acceptor-fluorophore-labeled antibody. When binding occurs, energy transfer produces a signal inversely proportional to the drug concentration. The workstation software processes the fluorescence signal, comparing it against a 10 ng/mL cutoff calibrator to provide a qualitative positive or negative result. The device is intended for use in central laboratories; results are preliminary and require confirmation by GC/MS or LC/MS/MS. The system aids healthcare providers in identifying potential PCP use, necessitating professional judgment for clinical decision-making.
Clinical Evidence
No clinical data. Performance was established via bench testing, including precision studies (n=88 per concentration level), analytical specificity (testing 40,000 ng/mL for cross-reactants), and a method comparison study (n=246 samples) against GC/MS reference methods. Method comparison showed 100% agreement among positives and 99% agreement among negatives.

L. Test Principle:
The RapidFRET Oral Fluid Assay for PCP is a competitive immunoassay used to detect PCP in human oral fluid. It is a homogenous assay that involves energy transfer between an acceptor fluorophore labeled to an antibody and a donor fluorophore labeled to drug. The assay is based on competition between drug in the sample and drug labeled with the donor fluorophore for a fixed number of binding sites on the antibody reagent. When acceptor and donor fluorophores are brought into close proximity through a binding event, energy transfer occurs. The fluorescence resonance energy transfer (FRET) signal is measured at the wavelength of the acceptor fluorophore and is inversely proportional to the amount of drug in the sample. A Cutoff Calibrator is used to translate the sample measurement into a positive or negative result. Controls are used to monitor the precision and accuracy of the assay.
M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
Three independently manufactured lots of RapidFRET reagent were evaluated in the precision study at concentrations of negative (zero),
{4}
cutoff, +/-25%, +/-50%, +/-75% and 100% of the cutoff. All data was generated in-house in a simulated laboratory environment using a single RapidFRET Integrated Workstation instrument. Study data collection days typically had 4 complete runs per day with singlicate data collected for each PCP concentration during each run.
Representative data from lot 1 is summarized below. The percentage of negative and positive results was consistent across the three lots tested.
Precision data from lot 1 was collected over 43 days total with 22 data collection days. Two professional laboratory operators were used to collect this data. Results are summarized below.
| Analyte | Concentration (eg, -75%) | Number of Determinations | Number of negative results | Number of positive results |
| --- | --- | --- | --- | --- |
| PCP | 0 | 88 | 88 | 0 |
| PCP | -75% | 88 | 88 | 0 |
| PCP | -50% | 88 | 88 | 0 |

b. Linearity/assay reportable range:
Not applicable. This is a qualitative assay.
c. Traceability, Stability, Expected values (controls, calibrators, or methods):
Traceability – Calibrators and Controls
Calibrators and controls are ready-to-use synthetic oral fluid solutions.
The cutoff calibrator and controls are prepared by spiking known concentrations of PCP into synthetic oral fluid to obtain the cutoff level calibrator, and the positive and negative controls. The negative calibrator is drug free synthetic oral fluid.
Calibrators and controls are prepared from Phencyclidine, 1 mg/mL in methanol commercial primary standards, which use NIST traceable weights and specific assays, such as GC/MS, to confirm drug levels. Certificates of Analysis are available for all standards at time of purchase.

# Stability - Calibrators and Controls
Real-time stability studies were conducted for the calibrators and controls. Protocols and acceptance criteria were reviewed and found to be acceptable. The shelf life (closed-vial) claim for the calibrators and controls is 12 months when stored at 2 - 8°C. The opened-vial claim for the calibrators and controls is 30 days when stored at 2 - 8°C.
# Value Assignment – Calibrators and Controls
Calibrator and Control lots are value assigned during the manufacturing process in two steps. First, following bottling and labeling, sampled vials are assayed against at least one previously accepted, released and unexpired Calibrator and Control lot using Rapid FRET reagents. Results are qualitatively evaluated for performance relative to the previously accepted lots. Second, each new manufactured lot of Calibrator or Control (POS and NEG) is quantitatively confirmed by GC/MS for target analyte concentration externally by a SAMHSA certified lab. Protocols and acceptance criteria were reviewed and found to be acceptable.
# Sample Shipping Study
To evaluate shipping stability, oral fluid pool samples were prepared at approximately 0%, 25%, 50%, 75%, 100%, 125%, 150%, 175% and 200% of the cutoff, mixed thoroughly and poured into a Rapid EASE Collector to mimic actual usage as closely as possible. Samples were packaged according to the Rapid EASE product insert and carrier instructions and shipped multiple times from California to Maine and back again. Following shipping, all samples were assayed with Rapid FRET reagents against GC/MS quantified calibrators and controls. During the 17 day study, temperatures ranged from approximately 4 – 30°C and the relative humidity (RH) ranged from 7% to 100%. The data support the sponsor’s shipping claim stability of up to 7 days. Recoveries comparing pre-shipping concentrations vs. post-shipping concentrations ranged from 92% to 100%.
# Sample Stability Study
In this study a neat oral fluid pool was spiked with PCP at 0 - 200% of cutoff corresponding to approximately 0 ng/ml, 2.5 ng/ml, 5.0 ng/ml, 7.5 ng/ml, 10 ng/ml, 12.5 ng/ml, 15 ng/ml, 17.5 ng/ml and 20 ng/ml. Six sets of nine samples each (54 total spikes) were prepared and 2 sets (18 samples) were stored at room temperature, two sets (18 samples) were stored refrigerated and the remaining two sets (18 samples) were frozen. Samples from each set were periodically assayed with the Rapid FRET Oral Fluid Assay for PCP using GC/MS confirmed calibrators and
{6}
controls. Recovery for samples stored at room temperature ranged from 100% to 111.5%. Recovery for refrigerated samples ranged from 100% to 110.7%, and for frozen samples ranged from 92% to 108.7%. Samples are stable for up to 7 days at room temperature, up to 21 days at 2 – 8°C, and up to six months at -10 to -25°C.
## Sample Recovery Study
A sample recovery study was performed in conjunction with the precision studies. An oral fluid pool was spiked with known quantities of PCP at nine different levels between 0 ng/mL and 20 ng/mL. These spikes were processed through a new RapidEASE Oral Fluid collector including the funnel, mimicking as close as possible actual collection protocol. The sample was then stored according to the product package insert and samples were removed for analysis by the reference method (GC/MS). Recoveries ranged from a low of 86% to a high of 104%. Results are summarized in the table below:
| Target Value (ng/mL) | Measured Value Mean (ng/mL) | Percent Recovery |
| --- | --- | --- |
| 0 | 0.0 | n/a |
| 2.5 | 2.6 | 104 |
| 5.0 | 4.5 | 90 |
| 7.5 | 6.9 | 92 |
| 10.0 | 9.1 | 91 |
| 12.5 | 10.9 | 87 |
| 15.0 | 12.9 | 86 |
| 17.5 | 15.3 | 87 |
| 20.0 | 17.7 | 88 |

f. Assay cut-off:
Characterization of how the device performs analytically around the claimed cutoff concentration appears in the precision section, M.1.a, above.
2. Comparison studies:
a. Method comparison with predicate device:
The sponsor performed a method comparison study with 246 oral fluid samples with concentrations ranging from 0 – 18, 915 ng/mL PCP. Because of the difficulty in finding native near-cutoff samples, 15 of the 246 samples were prepared by diluting a high concentration sample. Each of the diluted samples was made from a single dilution of a unique high concentration sample. Results are summarized below:
{11}
| | Negative by the predicate device or less than half the cutoff concentration by GC/MS analysis | Near Cutoff Negative (Between 50% below the cutoff and the cutoff concentration) | Near Cutoff Positive (Between the cutoff and 50% above the cutoff concentration) | High Positive (greater than 50% above the cutoff concentration) |
| --- | --- | --- | --- | --- |
| Positive | 0 | 1* | 11 | 107 |
| Negative | 114 | 13 | 0 | 0 |
* The concentration of PCP in this sample was 9 ng/mL as measured by GC/MS
Agreement among positives is 100% (118/118)
Agreement among negatives is 99% (127/128)
