Which is more accurate for genetic testing, resection specimens or blood, mainly depends on the patient's disease status. For example, in the early stages of some cancers, the cancer cells have not yet penetrated into the blood, so tissue slices must be used for testing. The results are more accurate and scientific, so if possible, it is best to choose tissue sections.
Gene testing of histopathological sections has the highest accuracy and is recognized as the gold standard in the industry. But it is not 100% perfect (for example, there are also issues of space, time, and heterogeneity). Where conditions permit, tissue samples should be given priority. Unless the patient cannot obtain enough tissue, or the tissue specimen is old, in this case, blood specimens can also be considered as a reluctant replacement. Compared to tissue biopsies, which require surgery or needle sampling, blood tests are easier to perform, produce results faster, and are non-invasive. However, not all genetic mutations in tumor patients can be detected in the blood, especially in the early stages of tumors, where the positive detection rate is even lower.
If you want to know more about genetic testing, it is recommended to consult Heprox. The patented reagent independently developed by Heprox can accurately capture the DNA fragments of different cancers. The capture success rate of these patented reagents is over 99%, and the capture depth is highly uniform. Information-rich and complete DNA libraries can be obtained to provide strong support for further cancer analysis. ● Is it necessary to do genetic testing if I am not sick?
