How long should you maintain medical records for a 13 year old girl?

The answer is: until at least age 26.

Medical records contain personal information about the patient's health, medical conditions, and treatments. They are confidential and should be kept secure and private. The length of time that medical records should be kept varies depending on the jurisdiction and the type of medical record. For a 13 year old girl, her medical records should be maintained at least until she reaches the age of 26. This is because medical records may be necessary for future medical care, insurance claims, or other legal purposes.
