Used for the quantitative measurement of prostate-specific antigen (PSA) levels in human serum or plasma, this ELISA kit serves as a critical tool in clinical diagnostics and research. It enables early detection and monitoring of prostate-related conditions, particularly prostate cancer. The assay is widely used in screening programs to assess the risk of malignancy and to support diagnosis alongside digital rectal exams and biopsies. It is also employed to monitor disease recurrence after treatment, such as surgery or radiation therapy, by tracking changes in PSA levels over time. In research settings, the kit helps evaluate the effectiveness of new therapies and study the biology of prostate diseases. Its high sensitivity and specificity make it suitable for detecting low concentrations of PSA, allowing for precise and reliable results in both clinical and laboratory environments.
