The Allen test is a method of examination physicians use to examine arterial blood flow into the hands. Originally developed in 1929, the test was modified and arguably improved in 1952. Physicians have since attempted many adjustments, but few have excelled in popularity like the originals.

Conditions

"Condition" is a general term for particular abnormal diseases that negatively affect a part or all of the body. Conditions are not due to any external injury. Therefore, a broken bone does not classify as a condition, whereas Herpes, OCD, Shingles, and Ulcers do.

Medical conditions are classified by specific symptoms and signs. While each person's experiences can vary, there are consistent signs and symptoms that doctors will look for when diagnosing their patients. We always recommend that people seek a professional diagnosis. Afterward, supplement medical advice and opinion with accurate and easy to read information.

Most people only spend an average of a couple minutes with their doctor during a checkup. Oftentimes patients don't receive the fullest explanation of their diagnosis. Easily search through the vast amount of articles that Facty Health offers for ones that address your specific needs. From there, allow us to help you with those unanswered questions.
