AMH testing is widely used in fertility evaluation, ovarian reserve assessment, and assisted reproductive medicine. Cnpair provides high-performance antibodies and antigens for AMH detection, featuring reliable immunoreactivity, good batch-to-batch consistency, and broad platform compatibility across CLIA, EIA, and LF, supporting the development of robust reproductive hormone assays. - AMH antigen - AMH antibody [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/amh/) ## [Human Chorionic Gonadotropin (HCG)](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/hcg/) HCG is a glycoprotein hormone produced primarily by placental trophoblasts during pregnancy and is one of the most widely used biomarkers for pregnancy detection. HCG testing is essential for early pregnancy detection and can also support pregnancy monitoring and the assessment of certain pregnancy-related conditions. Cnpair provides high-performance antibodies and antigens for HCG detection, offering strong antibody-pairing performance, with compatibility across CLIA, EIA, and LF platforms for the development of reliable pregnancy testing solutions. - HCG antibody [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/hcg/) ## [Luteinizing Hormone (LH)](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/LH/) LH is an important reproductive hormone secreted by the pituitary gland and plays a key role in follicular development, ovulation, and reproductive function. LH testing is widely used for fertility assessment, ovulation prediction, menstrual cycle monitoring, and the evaluation of reproductive and endocrine disorders. Cnpair provides high-performance antibodies for LH detection, featuring strong target recognition and pairing capability, with broad compatibility across CLIA, EIA, and LF platforms to support the development of reliable reproductive hormone assays. - LH antibody [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/LH/) ## [Follicle-Stimulating Hormone (FSH)](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/FSH/) FSH is an important reproductive hormone secreted by the pituitary gland, regulating follicular development and ovarian function in females and supporting spermatogenesis in males. FSH testing is widely used in fertility evaluation, reproductive health assessment, and the diagnosis of endocrine and reproductive disorders. Cnpair provides high-performance antibodies for FSH detection, demonstrating stable immunoreactivity and consistent batch performance, with compatibility across CLIA, EIA, and LF platforms for reproductive hormone assay development. - FSH antibody [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/FSH/) ## [TORCH](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/TORCH/) TORCH refers to a group of infections that may affect maternal and fetal health, commonly including Toxoplasma gondii, Rubella virus, Cytomegalovirus (CMV), and Herpes simplex virus (HSV). TORCH testing is widely used in prenatal screening, infection risk assessment, and maternal-fetal health monitoring. Cnpair provides a range of antigens, for key TORCH targets, offering broad target coverage and flexible platform compatibility across CLIA and EIA, supporting the development of comprehensive prenatal screening assays. - TOXO antigen - CMV antigen - HSV-2 antigen [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/TORCH/) ## [Sperm Protein 10 (SP10)](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/SP10/) SP10 is a sperm-specific protein associated with sperm development and maturation and has been investigated as a potential biomarker in male reproductive health and sperm-related testing. SP10 detection can support the development of immunoassays for sperm identification and reproductive health assessment. Cnpair provides high-performance antibodies and antigens targeting SP10, featuring strong target recognition and reliable immunoreactivity, with compatibility on LF for the development of sperm-related diagnostic solutions. - SP10 antigen - SP10 antibody [→](https://www.cnpairbio.com/immunoassay-diagnostics/fertility/SP10/) ## FAQ ### Can Cnpair provide free sample？ Yes.
