What is it?

Monospot is a quick blood test to help your caregiver decide if you have infectious (in-FEK-shus) mononucleosis (mah-no-NEW-klee-o-sis). This infection is also called "IM," "mono," or the "kissing disease."

Why do I need it?

Mono is usually a mild disease most often found in young adults. Your caregiver may want you to have this test done if you have:

  • Fever.
  • Fatigue (feel tired).
  • Sore throat.
  • Enlarged (swollen) lymph nodes.
  • Enlarged spleen.
  • Abdominal (belly) pain.

How do I get ready for the test?

Your caregiver will tell you when to have your blood test done. The blood test may be done before or after eating.

How is the specimen collected?

A caregiver will put a wide rubber strap around your arm and tighten it. Your skin will be cleaned with alcohol. A small needle attached to a special test tube will be put into a vein in your arm or hand. The tube has suction to pull the blood into it. When the tube is full, the rubber strap, needle and tube are removed. The caregiver will press a piece of cotton where the needle was removed. You may be asked to hold the cotton on the site for a few minutes to help stop the bleeding. Tape may then be put over the cotton on your arm.

What do I do after the test?

You may remove the tape and cotton in about 20 to 30 minutes. Call your caregiver to get the results of your test. Your caregiver will explain what your test results mean for you. Follow the instructions of your caregiver.
