Molecular testing is a laboratory technique used to analyze genetic material, such as DNA or RNA, to identify specific genes, mutations, or pathogens. This type of testing can help diagnose diseases, determine treatment options, and assess the risk of inherited conditions. It is commonly used in fields like oncology, infectious diseases, and genetics. The process often involves collecting a sample, such as blood or tissue, and using various methods to examine the molecular structure. Results can provide valuable information for healthcare providers and patients, guiding decisions about personalized medicine and targeted therapies.
