Development of a digital anti-Müllerian hormone immunoassay: ultrasensitive, accurate and practical strategy for reduced ovarian reserve monitoring and assessment. Talanta 2023; 253:123970. [PMID: 36206626 DOI: 10.1016/j.talanta.2022.123970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 09/18/2022] [Accepted: 09/24/2022] [Indexed: 12/13/2022]
Abstract
Anti-Müllerian hormone (AMH) is an ideal biomarker for the assessment of ovarian reserve. However, its application in determining ovarian reserve reduction is restricted due to the low sensitivity of existing AMH assays. Herein, a homebrew ultrasensitive digital AMH assay (UD-AMH) was established based on a single-molecule array (SiMoA, HD-X platform), and the analytical performance of UD-AMH was evaluated systematically. The limit of detection (LoD) and limit of quantitation (LoQ) of UD-AMH were 0.13 and 0.14 pg/mL, respectively, which is approximately 100-fold higher than that of the current reported general clinical AMH assay. A comparison study showed a high correlation, with r = 0.988 for the Beckman Access AMH assay and r = 0.945 for the Kangrun AMH assay. In addition, we found that the AMH concentrations of premature ovarian insufficiency (POI) patients were very low (2.59 (0.86, 31.79) pg/mL) and similar to those of perimenopausal women (2.37 (0.65, 35.88) pg/mL) but significantly higher than those of menopausal women (0.43 (0.28, 1.17) pg/mL). Furthermore, we observed that the AMH concentration of most hormone therapy (HT) treated POI patients decreased sharply, suggesting that the ovarian reserve of POI patients declines over time even under HT-treatment.

J Immunol Methods 2021; 494:113059. [PMID: 33895196 DOI: 10.1016/j.jim.2021.113059] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 04/19/2021] [Accepted: 04/19/2021] [Indexed: 11/29/2022]
Abstract
Anti-Müllerian hormone (AMH) is known as a reliable marker of ovarian reserve (OR). The determination of AMH is of great importance and most existed AMH detection methods are heterogeneous immunoassay. In this study, a novel homogeneous sandwich immunoassay-light-initiated chemiluminescence assay (LICA) for detecting AMH serum level was developed. This AMH-LICA was performed by incubating serum samples with AMH mouse monoclonal antibody coated with chemibeads, streptavidin-coated sensibeads, and biotinylated AMH mouse monoclonal antibody. Sensitivity, precision, accuracy and cross-reactivity of this assay were evaluated. Besides, a regression analysis showed a high correlation between AMH-LICA and Roche Elecsys® AMH assay (y = 0.9851x + 0.07147, R2 = 0.9569). As a homogeneous immunoassay, this AMH-LICA could accurately and rapidly determine the serum level of AMH with high-throughput. Thus, this new developed assay may be a new useful analytical tool for the determination of AMH.

[PMID: 31646166 PMCID: PMC6804432 DOI: 10.1016/j.plabm.2019.e00140] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Revised: 09/23/2019] [Accepted: 09/26/2019] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVES Anti-Müllerian hormone (AMH) is increasingly used as a biomarker of ovarian reserve in clinical practice, and is used both for management of fertility treatments and prediction of menopause. We sought to validate the newly FDA-approved Ansh Laboratories MenoCheck picoAMH ELISA on the Dynex-DS2 platform for clinical use in our obstetrics and gynecology center. DESIGN Validation of the picoAMH ELISA on the Dynex-DS2 was performed according to CLSI guidelines. Intra- and inter-assay CV, assay linearity, and method comparison studies were carried out to verify assay precision and accuracy. The manufacturer's reference range was verified using 26 volunteer samples, and interference for hemolysis, lipemia, icterus, and biotin was evaluated. picoAMH results were additionally correlated with antral follicle count by ultrasound. RESULTS Intra- and inter-assay CV of the picoAMH assay on the DS2 was ≤4% and the assay was linear between concentrations of 0.0067-16.24 ng/mL (0.048-116.0 pmol/L) AMH. Method comparison was performed with the manufacturer's laboratory and indicated good correlation, with Deming regression yielding slope of 0.928 and intercept of -0.0421. The assay displayed no significant interference from hemolysis (1000 mg/dL), lipemia (2000 mg/dL), conjugated bilirubin (66 mg/dL), or biotin (10,000 ng/mL). Measurement of AMH on the DS2 was also correlated with antral follicle count, with R = 0.7128. CONCLUSIONS Our results indicate that the picoAMH ELISA on the DS2 has good analytical performance suitable for clinical use.
