Homologous Recombination Deficiency Detection Kit is developed for the qualitative detection of genomic homologous recombination deficiency (HRD) based on high-throughput sequencing technology, and adopts the combinatorial probe-anchor synthesis sequencing method. Tissue samples or paraffin-embedded tissue samples (FFPE) of solid tumor patients are applicable for this test. The test results and clinical evaluation of patients’ actual situations will help clinicians plan and propose precision treatment options to patients.
