Most cases of slapped cheek syndrome can be diagnosed by making a visual examination of the distinctive rash. No further testing is usually required in children.
In cases involving adults who have joint pain but no skin rash, a diagnosis of slapped cheek syndrome may be missed at first as the symptoms are often mistaken for arthritis or joint damage.
Because of this you may be referred for a series of blood tests and X-rays.
If there is doubt over a diagnosis, you may have a blood test to check the antibodies that your body produces as a response to infection. This results of this test will confirm a diagnosis.
High-risk groups
If you're in a high-risk group, for example, if you are pregnant or you have a weakened immune system, a blood test may be recommended if you have been in close contact with someone who is known to have the infection.
The blood test can be used to see if you are immune to the infection. If you are not immune, treatment can begin immediately to prevent complications.
