Biomarkers generally refer to a characteristic biochemical index of a common physiology, pathology, or treatment process that can be objectively measured and evaluated, through its determination, we can know the process of the biological process in which the body is currently in. Checking a disease-specific biomarker may play a helpful role in the identification, early diagnosis, prevention and treatment of the disease. Many traditional pharmaceutical companies and emerging biotechnology companies often use biomarkers to accelerate the drug development process and ensure product safety.

When designing the test of the kit, the first thing to be clear is the purpose of the biomarker data. For non-critical biomarkers, such as internal analysis, biomarker screening, etc., it can be designed according to actual needs.

Key biomarkers are required: standard curve and sample concentration test, parallelism and selectivity test, QC setting, etc.
