K. Test Principle:
The Elecsys AMH assay makes use of a sandwich test principle using monoclonal antibodies that are specifically directed against AMH. Endogenous AMH is bound by both a biotinylated monoclonal AMH-specific antibody and a monoclonal AMH-specific antibody labeled with a ruthenium complex to form a sandwich complex. Results are determined via a calibration curve which is instrument-specifically generated by a two-point calibration and a master curve provided via the reagent barcode.

b. Linearity/assay reportable range:
Linearity:
Linearity of the Elecsys AMH Assay were evaluated according to CLSI EP6-A. Three high level samples were diluted with postmenopausal female serum for a total of 15 concentration levels. Samples were assayed in triplicate on the cobas e 411 analyzer. The observed values were graphed against the calculated values and a linear regression was performed. Results are summarized in the table below:
Sample | Sample range (ng/mL) | Slope | Intercept | Correlation (r) |
---|---|---|---|---|
Set 1 | 0.004 – 27.5 | 1.0091 | 0.0105 | 0.999 |
Set 2 | 0.004 - 27.4 | 1.0054 | 0.0205 | 0.999 |
Set 3 | 0.004 - 25.8 | 1.0063 | 0.0013 | 0.999 |
The linear regression results support the Applicant's claimed measuring range (0.03
5
ng/mL - 23 ng/mL).
Dilution:
A dilution study was performed by diluting six human samples with Diluent Universal in 1:2 ratio both manually and by the analyzer. The data support the following instruction for use:
Samples with AMH concentrations above the measuring range can be diluted automatically with Diluent Universal 2. Manual dilution can be performed with Diluent Universal 2. The recommended dilution is 1:2 (either automatically by the cobas e analyzer or manually). The concentration of the diluted sample must be > 10 ng/mL. After manual dilution, multiply the result by the dilution factor. After dilution by the analyzer, the cobas e software automatically takes the dilution into account when calculating the sample concentration.
- Traceability, Stability, Expected values (controls, calibrators, or methods): C.
Traceability:
The AMH CalSet are traceable to manufacturer's internal reference standards (Master Calibrators), which consist of a panel of well characterized serum reference materials covering the entire measuring range. The Applicant submitted a detailed traceability assurance plan which was reviewed and found to be acceptable. The target values for AMH CalSet are shown below:

Clinical Studies:
The use of AMH for the assessment of ovarian reserve was investigated in a multicenter, prospective, non-interventional study with N = 856 women presenting at fertility clinics for evaluation. Patient BMI included in the study ranged from 14.76 to 39.99, as shown below:

BMI | N |
---|---|
30.00-39.99 | 158 |
AMH values were correlated to the antral follicle count (AFC) of the women. AFC was determined by transvaginal ultrasonography (TVUS), which measures antral follicles (2-10 mm) of the ovary. Both AFC and AMH were determined on days 2-4 of the same menstrual cycle. Clinical serum samples were collected at 13 geographically diverse sites in the United States, and then tested at 3 laboratory sites in the United States on cobas e 411 analyzers.
Based on the AFC, two groups are defined: AFC ≤ 15 and AFC > 15. Correlation of AMH (using the 1.77 ng/mL cutoff) and AFC is presented in the table below (relationship is shown in both absolute numbers and percentages per AMH group):
AFC ≤ 15 | AFC > 15 | N | |
---|---|---|---|
AMH ≤ 1.77 ng/mL | 280 | ||

M. Proposed Labeling:
The labeling is sufficient and it satisfies the requirements of 21 CFR Parts 801 and 809 and the special controls for this device type.
N. Identified Risks and Identified Mitigations:
Identified Risks to Health | Identified Mitigations |
---|---|
Inaccurate test results that provide false positive results | |
may lead to a modification, delay or cancellation before a | |
controlled ovarian stimulation procedure is initiated. | General controls and special |
controls (1) and (2) | |
Inaccurate test results that provide false negative results | |
may lead to the development of ovarian hyperstimulation | |
syndrome in patients incorrectly thought to have normal | |
and/or diminished ovarian reserve. | General controls and special |
controls (1) and (2) |

O. Benefit/Risk Analysis:
Summary | |
---|---|
Summary of | |
the Benefit(s) | The primary benefit of the Elecsys AMH system is its use in the prediction (in |
conjunction with other clinical and laboratory findings) of high ovarian | |
reserve. The assessment of ovarian reserve prior to performing controlled | |
ovarian stimulation (COS) can assist in the reduction of risk of patients | |
developing ovarian hyperstimulation syndrome (OHSS) by identifying those | |
patients with a higher OHSS risk (i.e., those with high ovarian reserve levels, | |
which correspond to an antral follicle count (AFC) of >15). | |
The AMH cut-off corresponding to an AFC > 15 was validated with a | |
sensitivity and specificity of 88.3% and 68.3%, respectively. | |
Summary of | |
the Risk(s) | The primary risks to patients through the use of the device are related to the |
consequences of clinical decisions based on false positive and the more | |
clinically significant false negative results. | |
False positive results may lead to a modification, delay or cancellation before | |
a controlled ovarian stimulation procedure is initiated. Modifications to a | |
stimulation regimen may lead to less oocytes for fertilization. False positive | |
results may result in the need for a repeat procedure and cancelled or delayed | |
stimulation. | |
False negative results may lead to the development of ovarian | |
hyperstimulation syndrome, a potentially life-threatening condition, in | |
patients incorrectly thought to have normal and/or diminished ovarian reserve. | |
However, this risk can be mitigated through appropriate labeling indicating | |
that AMH assay is intended to be used for assessing the ovarian reserve in | |
conjunction with other clinical and laboratory findings before starting any | |
fertility therapy, and should be used in conjunction with Antral Follicle Count. | |
Additional risks to patients and laboratory workers include those that are | |
associated with routine phlebotomy performed as standard practice in a | |
clinical setting. | |
Summary of | |
Other Factors | There are no additional factors to consider. |
Summary | |
Conclusions | |
Do the | |
probable | |
benefits | |
outweigh the | |
probable risks? | Given the performance characteristics, applicable general controls, including |
design controls, and proposed special controls, including labeling | |
mitigations, the probable benefits outweigh the probable risks for this device. |
