Intended Use
The DSL-10-8500 ACTIVE™ Free 3-hCG Enzyme-Linked Immunosorbent Assay (ELISA) kit provides materials for the quantitative measurement of Free ß-subunit of human chorionic gonadotropin (hCG) in serum. This assay is intended for in vitro diagnostic use as an aid in the detection of pregnancy.
Device Description
The DSL-10-8500 ACTIVE™ Free B-hCG ELISA kit was developed for the quantitative measurement of Free ß-subunit of human chorionic gonadotropin (hCG) in human serum. The DSL ACTIVE® Free B-hCG ELISA is a two-site ELISA assay in which the free ß-hCG to be measured is "sandwiched" between two antibodies. The first antibody is immobilized to the inside wall of the microtitration well, the other antibody is conjugated to the enzyme horseradish peroxidase for detection. The analyte present is bound by both the antibodies to form a "sandwiched" complex. Unbound materials are removed by washing the wells. The resultant is analyzed in a spectrophotometer for absorbance. The amount of bound Free B-hCG is directly proportional to the concentration of the Free ß-hCG present in the sample.

Explanation: The "Intended Use / Indications for Use" section explicitly states "This assay is intended for in vitro diagnostic use as an aid in the detection of pregnancy."

No

The device is an in vitro diagnostic (IVD) kit that uses chemical reagents and a physical assay method (ELISA) to measure a substance in serum. It is not a software-only device.

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

The "Intended Use / Indications for Use" section explicitly states: "This assay is intended for in vitro diagnostic use as an aid in the detection of pregnancy." This statement directly identifies the device as an in vitro diagnostic product.

Device Description

The DSL-10-8500 ACTIVE™ Free B-hCG ELISA kit was developed for the quantitative measurement of Free ß-subunit of human chorionic gonadotropin (hCG) in human serum. Human chorionic gonadotropin (hCG) is a glycoprotein secreted by the trophoblastic cells of the placenta. hCG is composed of two dissimilar non-covalently linked polypeptides known as the or- and ßsubunits [1].

The DSL ACTIVE® Free B-hCG ELISA is a two-site ELISA assay in which the free ß-hCG to be measured is "sandwiched" between two antibodies. The first antibody is immobilized to the inside wall of the microtitration well, the other antibody is conjugated to the enzyme horseradish peroxidase for detection. The analyte present is bound by both the antibodies to form a "sandwiched" complex. Unbound materials are removed by washing the wells. The resultant is analyzed in a spectrophotometer for absorbance. The amount of bound Free B-hCG is directly proportional to the concentration of the Free ß-hCG present in the sample. The antibodies were raised against sterically remote epitopes on the beta subunit of hCG, such that in intact hCG molecules, these antibody recognition sites are not available. The DSL ACTIVE® Free M-RCG ELISA is very specific for free ß-hCG without cross-reactivity or interference due to LH, FSH, AFP, TSH or prolactin.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

To demonstrate substantial equivalence between the two assays, pregnant patient samples (n=98) were collected and assayed using both methods. Samples were chosen based on expected hCG levels so that samples with low, intermediate and high levels would be evaluated. Linear regression analysis of the results obtained for the comparison gave the equation: DSL-10-8500 = 0.007(DSL-8300) - 2.7, with a correlation coefficient of r = 0.82 and p

Test Description:

The DSL-10-8500 ACTIVE™ Free B-hCG ELISA kit was developed for the quantitative measurement of Free ß-subunit of human chorionic gonadotropin (hCG) in human serum. Human chorionic gonadotropin (hCG) is a glycoprotein secreted by the trophoblastic cells of the placenta. hCG is composed of two dissimilar non-covalently linked polypeptides known as the or- and ßsubunits [1]. The or-subunit is very similar to the ox-chain of lutropin (hLH), follitropin (hFSH), and thyrotropin (hTSH). The ß-subunit is responsible for the biological activity of this hormone [1,2].

The primary utility of hCG measurement is for the early detection and monitoring of pregnancy, and pregnancy related disorders. Healthy, non-pregnant individuals have low (
