Intended Use
The HE4 EIA is an enzyme immunometric assay for the quantitative determination of HE4 in human serum. The assay is to be used as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer. Serial testing for patient HE4 assay values should be used in conjunction with other clinical methods used for monitoring ovarian cancer.
Device Description
The HE4 EIA is a solid-phase, non-competitive immunoassay based upon the direct sandwich technique based on two mouse monoclonal antibodies, 2H5 and 3D8, directed against two epitopes in the C-WFDC domain of HE4. Calibrators, controls and patient samples are incubated together with biotinylated Anti-HE4 monoclonal antibody (MAb) 2H5 in streptavidin coated microstrips. HE4 present in calibrators or samples is adsorbed to the streptavidin coated microstrips by the biotinylated Anti-HE4 MAb during the incubation. The strips are then washed and incubated with HRP labeled Anti-HE4 MAb 3D8. After washing, buffered Substrate/Chromogen reagent (hydrogen peroxide and 3, 3', 5' tetra-methyl-benzidine) is added to each well and the enzyme reaction is allowed to proceed. During the enzyme reaction a blue color will develop if antigen is present. The intensity of the color is proportionate to the amount of HE4 present in the samples. The color intensity is determined in a microplate spectrophotometer at 620 nm (or optionally at 405 nm after addition of Stop Solution). Calibration curves are constructed for each assay by plotting absorbance value versus the concentration for each calibrator. The HE4 concentrations of patient samples are then read from the calibration curve.

The device description details a standard immunoassay technique and data analysis based on a calibration curve, with no mention of AI or ML algorithms.

No.
This device is an in vitro diagnostic (IVD) assay designed to quantitatively determine HE4 in human serum, used as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer. It provides diagnostic information, not therapy.

Yes

The "Intended Use / Indications for Use" states that the assay is to be used "as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer," which directly indicates a diagnostic purpose.

No

The device description clearly outlines a laboratory-based immunoassay involving physical reagents, microstrips, and spectrophotometry, which are hardware components. It is not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of HE4 in human serum" and is used "as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer." This involves testing a sample taken from the human body (serum) outside of the body to provide information about a medical condition.
  • Device Description: The description details a laboratory assay (enzyme immunometric assay) performed on serum samples using reagents and a microplate spectrophotometer. This is a typical setup for an in vitro diagnostic test.
  • Performance Studies: The performance studies describe testing on "serial serum samples from 80 patients" and analyzing the results in relation to "disease status." This further confirms the use of the device to analyze biological samples for diagnostic purposes.
  • Predicate Device: The mention of a predicate device (ABBOTT ARCHITECT CA 125 II Assay) which is also an IVD, suggests that this device falls within the same regulatory category.

All of these points align with the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

Precision: A study was performed with the HE4 EIA Kit modeled after the NCCLS (CLSI) guideline EP5-A2. A panel of four serum samples was assayed, using two lots of reagents, in replicates of two, at two separate times per day for 20 days. The HE4 EIA Kit precision is ≤ 15% total CV.

Linearity: A dilution linearity study was conducted for the HE4 EIA Kit modeled affer the NCCLS (CLSI) guideline EP6-A. Serum samples with elevated HE4 values were diluted with HE4 Calibrator A (zero). The HE4 concentration was determined for each dilution and the percent (%) recovery was calculated. The HE4 EIA Kit was determined to have a mean recovery within 15% of the expected result for diluted samples.

Functional Sensitivity: The functional sensitivity of the HE4 EIA Kit is ≤ 25 pM. The functional sensitivity is expressed as the concentration of an analyte at which the CV is 20%. The NCCLS guideline EP5-A2 was used to design the experiments for determination of functional sensitivity. A study was conducted where a five member sensitivity panel was tested in replicates of 4 in 2 runs on twenty separate days with two lots of reagents. The functional sensitivity determined for the HE4 EIA was found to be
