What happens during an OCD test?
Your primary care provider may give you a physical exam and order blood tests to find out if your symptoms are being caused by certain medicines, another mental illness, or other physical disorders.
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.
You may be tested by a mental health provider in addition to or instead of your primary care provider. A mental health provider is a health care professional who specializes in diagnosing and treating mental health problems.
If you are being tested by a mental health provider, he or she may ask you detailed questions about your thoughts and behaviors.
