What happens during a dengue fever test?Your health care provider will probably ask about your symptoms and for details on your recent travels. If an infection is suspected, you will get a blood test to check for the dengue virus.During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
