Testing & Diagnosis for Sarcoidosis in Children

How is sarcoidosis diagnosed?

Since sarcoidosis can affect so many different parts of the body, and may have such varying symptoms in different people, diagnosing sarcoidosis is typically difficult and delayed.

The first step is to consider sarcoidosis as a possible cause of difficult-to-explain symptoms. Your child's physician will obtain a complete prenatal and birth history and ask if your child has had any recent colds or other infections. The diagnosis is usually confirmed through a combination of:

  • reported symptoms
  • laboratory tests - certain blood tests, for example, may help rule out other conditions that can mimic sarcoidosis
  • x-rays - a diagnostic test which uses electromagnetic energy to produce images of internal tissues, bones and organ on film
  • vision test/eye examination
  • biopsy - a small sample of areas thought to be affected by granulomas may be taken for microscopic examination to help confirm the presence of sarcoidosis
