Nosebleed Exams and Tests
Nosebleed Exams and Tests To examine the nose, the doctor places medications into the nostrils, usually with a cotton ball, that numb the inside of the nose as well as constrict the blood vessels in that area. This will also reduce swelling and allow the doctor to see inside the nose better The diagnosis of a posterior nosebleed is usually made when attempts to control the bleeding when the measures used for an anterior nosebleed have failed. Seeing the source of a posterior nosebleed is nearly impossible. Lab tests may be done to evaluate blood loss or the effects of blood thinning drugs.
