| 概要≠ | IVF Embryo Grading is a standardized morphological assessment system for evaluating the quality and viability of embryos in assisted reproductive technology. First formalized by Gardner and colleagues in 1999, it uses microscopic examination to score embryos across multiple criteria, enabling clinicians to select the most viable embryos for transfer and improve pregnancy outcomes. | Somatic Cell Count (SCC) is a quantitative measure of the concentration of white blood cells and epithelial cells in milk, used as a primary indicator of udder health and the presence of mastitis in lactating cattle. Standardized by veterinary regulatory agencies worldwide, SCC serves as a non-invasive, cost-effective screening tool in dairy herd management and milk quality assessment. |
