The summary describes a quantitative immunoassay using surface plasmon resonance (SPR) for hCG detection. There is no mention of AI, ML, image processing, or any data analysis techniques that would typically involve AI/ML. The performance studies focus on standard analytical and clinical validation metrics for an immunoassay.
No
The device is an automated analyzer used to detect pregnancy by measuring hCG levels; it does not directly treat or manage a disease or condition.
Yes
The device measures hCG levels in whole blood to aid in the early detection and determination of pregnancy, which is a diagnostic purpose.
No
The device description explicitly states it uses a "PrePaQ Cartridge" and a "FasTraQ Automated Analyzer" which are hardware components used to perform the assay. The technology is based on surface plasmon resonance (SPR), which is a physical phenomenon requiring hardware.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for "quantitative measurement of human chorionic gonadotropin (hCG) in whole blood for the determination of pregnancy." This is a diagnostic test performed on a biological sample (whole blood) outside of the body.
- Device Description: The description details a "sandwich immunoassay in combination with SPR surface mass measurement" using a "solid phase ß-hCG monoclonal antibody immobilized onto a gold surface" and an "anti-alpha hCG polyclonal antibody conjugated to alkaline phosphatase." This describes the components and methodology of an in vitro diagnostic assay.
- Sample Type: The assay is used with "patient whole blood samples." This is a biological specimen.
- Performance Data: The document provides extensive performance data including analytical sensitivity, precision, interfering substances, hook effect, normal range, and patient sample correlation. This type of data is characteristic of the validation required for IVD devices.
- Predicate Device: A predicate device (AVDIA Centaur) is mentioned, which is a common requirement for demonstrating substantial equivalence for IVD submissions to regulatory bodies.
All of these factors clearly indicate that the FasTraQ Automated Analyzer in conjunction with the PrePaQ Total hCG Cartridge is an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Normal Range - Testing of apparently healthy individuals demonstrated that the Quantech Total 3-hCG Assay and the predicate device perform similarly at and below the accepted value for determination of pregnancy (greater than 25 mlU/ml). The 95% normal range of the Quantech hCG assay was 8.2 mlU/ml compared to 2.8 mlU/ml for the Centaur hCG assay.
The Quantech device demonstrates no false positive results with these apparently healthy individuals and is in 100% agreement with the predicate device.
Patient Sample Correlation - Results from human samples with values distributed throughout the quantitative range of the Quantech hCG assay, were compared with those obtained with a commercially available methods. The internal paired sample comparison resulted in a correlation coefficient of 0.97 (slope = 0.67. intercept = 1.47) with the Bayer Centaur (predicate device). The external paired sample comparison resulted in a correlation coefficient of 0.93 (slope 0.89, intercept -1.7992) with the Abbott AxSym.

CLIA Categorization
We believe the Quantech FasTraQ Automated Analyzer and PrePaQ Total β-hCG assy to be moderately categorized based on previous classifications of medical devices and analogous tests.
Substantial Equivalence
The Quantech FasTraQ Automated Analyzer and PrePaQ Total ß-hCG assay are substantially equivalent to the AVDIA Centaur (predicate device) marketed by Bayer Corporation since 1997 as well as other commercially available devices and assays (i.e., Abbott AxSym and Dade Behring RxL).
Intended Use
The FasTraQ Automated Analyzer in coniunction with the PrePaQ Total hCG Cartridge is intended for use as an aid in the early detection of pregnancy where rapid, quantitative results in the emergency department or where other rapid diagnostics are required. The assay is to be used with patient whole blood samples.
Device Description
The PrePaQ Cartridge in coniunction with the FasTraQ Automated Analyer is use to quantitate hCG in whole blood using surface plasmon resonance (SPR). The Quantech PrePaQ Total ß-hCG assay is based on the principle of two site, or sandwich immunoassay in combination with SPR surface mass measurement. Each PrePaQ cartridge contains a solid phase ß-hCG monoclonal antibody immobilized onto a gold surface. An anti-alpha hCG polyclonal antibody conjugated to alkaline phosphatase is attached to the antigen to form the sandwich. An enhancing solution is used to further increase the mass on the surface.

Comparison of Technological Characteristics
The Quantech PrePaQ Total ß-hCG assay is similar to the Bayer Centaur Total ß-hCG assay as follows. Both assays are in vitro sandwich immunometric assays used for quantitative measurement to total ß-hCG. Although, the Quantech assay uses whole blood, both assays report the results in mIU/ml of serum or plasma. Both assays use a ß-hCG monoclonal antibody coated to a solid support. Both systems utilize a microprocessor for instrument control, data acquisition and data reduction.
Summary of Non-Clinical Performance Data
Dilution Linearity/Parallelism - The parallelism study was conducted to evaluate the linearity of the Quantech Total ß-hCG Assav. Whole blood samples were separately spiked with intact hCG and serially diluted with corresponding unspiked whole blood. The average percent of expected was 111%.
Recovery - Accuracy of the Quantech Total ß-hCG Assay was calculated from test results as the percentage of added analyte, corrected for endogenous analyte, recovered by the assay. After correcting for endogenous hCG content, the average recovery was 105%.
Analytical Sensitivity - Multiple duplicates of whole blood zero samples were assayed to determine the minimum quantity of hCG detectable by the Quantech Assay. The average SPR signal shift plus two standard deviations (2 S.D.) was calculated and translated into a dose. The calculated analytical sensitivity of the Quantech hCG assay is 2.5 mlU/mL.
Precision - The INTERASSAY precision was determined by evaluating three pools in triplicate on different days. The mean hCG concentrations (with % C.V.) were 57.1 (10.6%), 216.9 (8.1%), and 553.8 (5.9%) mlU/mL for the low, medium and high pools, respectively.
TOTAL IMPRECISION was determined from the interassay data, and is a combination of results from multiple runs on multiple days. The mean hCG concentrations (with % C.V.) were 57.2 (13.6%), 216.9 (12.8%), and 553.7 (9.0%) mlU/mL for the low, medium and high pools, respectively.
Interfering Substances - Physiological interference was evaluated by spiking a whole blood pools with hCG and hemoglobin, bilirubin and triglycerides at levels ten times the highest expected physiological concentration. The percent recovery of hCG was determined to be acceptable in all three solutions and no interference was noted by the endogenous substances in the Quantech PrePaQ Total β-hCG assay.
Hook Effect - Samples well beyond the standard curve range were assayed. No high dose hook effect was observed. Therefore, the Quantech Total ß-hCG Assay does not give erroneously low results for grossly elevated samples up to at least 100,000 mlU/mL.

Safety and Effectiveness Summary
Summary of Clinical Performance Data
Normal Range - Testing of apparently healthy individuals demonstrated that the Quantech Total 3-hCG Assay and the predicate device perform similarly at and below the accepted value for determination of pregnancy (greater than 25 mlU/ml). The 95% normal range of the Quantech hCG assay was 8.2 mlU/ml compared to 2.8 mlU/ml for the Centaur hCG assay.
The Quantech device demonstrates no false positive results with these apparently healthy individuals and is in 100% agreement with the predicate device.
Patient Sample Correlation - Results from human samples with values distributed throughout the quantitative range of the Quantech hCG assay, were compared with those obtained with a commercially available methods. The internal paired sample comparison resulted in a correlation coefficient of 0.97 (slope = 0.67. intercept = 1.47) with the Bayer Centaur (predicate device). The external paired sample comparison resulted in a correlation coefficient of 0.93 (slope 0.89, intercept -1.7992) with the Abbott AxSym.
Conclusions Drawn From Performance Tests
The Quantech Total ß-hCG Assay provides results which are internally accurate, unaffected by ordinary variation of sample matrix and equivalent to the results obtained using the approved device in a valid laboratory setting.
Additionally, both clinically-based studies (normal range, patient correlation) demonstrated essential equivalence between the devices as measured by their correlation and the degree to which assay results are linearly related to one another over a broad range of values. Likewise, the normal range evaluation provided empirical evidence that the assay value is similar for both devices, and in agreement with published data.
