Tests & Diagnosis
A diagnosis of Laron syndrome is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis and rule out other conditions that cause similar features. This generally includes blood tests to measure the levels of certain hormones that are often abnormal in people with Laron syndrome. For example, affected people may have elevated levels of growth hormone and reduced levels of insulin-like growth factor I. Genetic testing for changes (mutations) in the GHR gene can also be used to confirm a diagnosis in some cases.
