Improving Accuracy in Whole Genome Sequencing
Next-generation sequencing (NGS) is essential for clinical diagnostics, but limitations in variant detection arise from challenging genomic regions and low-frequency variants. Improvements in long-read sequencing and bioinformatics may enhance test accuracy. Additionally, standardization of workflows and the use of commutable reference materials are critical for reliable genetic testing across laboratories.
