What are the Sources of DNA in Pediatric Patients?
In pediatrics, DNA can be obtained from various sources including blood, saliva, buccal swabs, and tissue biopsies. Blood samples are often preferred due to their high DNA yield and quality. However, saliva and buccal swabs are non-invasive alternatives that are particularly useful for infants and young children. The choice of source depends on the patient's condition, the type of analysis required, and the feasibility of sample collection.
