Blood is the most common and reliable source for genetic testing, particularly for genetic disorders. Nucleated white blood cells (WBCs) in whole blood contain high-quality DNA, making it ideal for large-scale genomic sequencing and mutation detection. Genetic testing can help detect inherited diseases (e.g., cystic fibrosis, sickle cell anemia), identify mutations in oncogenes or tumor suppressor genes, or determine how individuals respond to drugs based on their genetic profile. molecular weight, an important criteria for long-read technologies next to high quality, which makes this kit very suitable for long read sequencing.
