## Indications for Use
Immunoassay for the in vitro determination of OC 125 reactive determinants. These determinants are associated with a high molecular weight glycoprotein in serum and plasma of women with primary epithelial invasive ovarian cancer, excluding those with cancer of low malignant potential. The Elecsys® CA 125II is indicated for use as an aid in the detection of residual or recurrent ovarian carcinoma in patients who have undergone first-line therapy and would be considered for diagnostic second-look procedures. The Elecsys CA 125II is further indicated for serial measurement of CA 125II to aid in the management of cancer patients.
## Device Story
Elecsys CA 125II is an in vitro diagnostic immunoassay for serum/plasma analysis. It utilizes a sandwich immunoassay principle: sample, biotinylated monoclonal antibody, and ruthenium-labeled monoclonal antibody form a complex; streptavidin-coated microparticles bind the complex to a solid phase. The reaction mixture is aspirated into a measuring cell; microparticles are magnetically captured on an electrode. Voltage application induces electrochemiluminescence, measured by a photomultiplier. Results are calculated via a 2-point calibration curve and a reagent-specific master curve. Used in clinical laboratories to aid in managing ovarian cancer patients and detecting recurrence. Output provides quantitative CA 125II levels, assisting clinicians in monitoring disease status and determining the need for second-look procedures.
## Clinical Evidence
Bench testing only. Precision studies (N=60 per sample) showed within-run CVs of 0.76-1.15% and total CVs of 2.13-3.13%. Method comparison against the predicate (N=93) yielded a correlation coefficient of r=0.997 (y=0.9614x - 2.15). Linearity established from 0.6 to 5,000 U/mL. No hook effect observed up to 24,000 U/mL.
## Technological Characteristics
Sandwich immunoassay using streptavidin-coated microparticles and electrochemiluminescence detection. Employs biotinylated and ruthenium-labeled monoclonal antibodies. Operates on the Elecsys 1010 analyzer. Assay range: 0.6-5,000 U/mL. Calibration via 2-point method and reagent bar-coded master curve.
## Regulatory Identification
A tumor-associated antigen immunological test system is a device that consists of reagents used to qualitatively or quantitatively measure, by immunochemical techniques, tumor-associated antigens in serum, plasma, urine, or other body fluids. This device is intended as an aid in monitoring patients for disease progress or response to therapy or for the detection of recurrent or residual disease.
## Special Controls
*Classification.* Class II (special controls). Tumor markers must comply with the following special controls: (1) A guidance document entitled “Guidance Document for the Submission of Tumor Associated Antigen Premarket Notifications (510(k)s) to FDA,” and (2) voluntary assay performance standards issued by the National Committee on Clinical Laboratory Standards.

4. The Elecsys® CA 125 II™ employs a sandwich test principle with Device monoclonal antibodies directed against CA 125 II and with streptavidin Description microparticles and electrochemiluminescence detection.
Total duration of assay: 18 minutes.
- · 1st Incubation: 40 ul of sample, a biotinylated monoclonal CA 125 IIspecific antibody and a monoclonal CA 125 II-specific antibody labeled with a ruthenium complex react to form a sandwich complex.
- 2nd Incubation: after the addition of streptavidin-coated microparticles, the complex becomes bound to the solid phase via interaction of biotin and streptavidin.
·The reaction mixture is aspirated into the measuring cell where the microparticles are magnetically captured onto the surface of the electrode. Unbound substances are then removed with ProCell. Application of a voltage to the electrode then induces chemiluminescent emission which is measured by a photomultiplier.
·Results are determined via a calibration curve which is instrumentspecifically generated by 2-point calibration and a master curve provided via the reagent bar code.
