Other Names for this Disease
- ED syndrome
- Ehlers Danlos syndrome
Tests & Diagnosis
A diagnosis of Ehlers-Danlos syndrome is typically based on the presence of characteristic signs and symptoms. Depending on the subtype suspected, some of the following tests may be ordered to support the diagnosis:
- Collagen typing performed on a skin biopsy is important for the diagnosis of vascular type, arthrochalasia type, and dermatosparaxis type. Collagen is a tough, fiber-like protein that makes up about a third of body protein. It is part of the structure of tendons, bones, and connective tissues. People with Ehlers-Danlos syndrome often have abnormalities of certain types of collagen.
- Genetic testing is available for most subtypes of Ehlers-Danlos syndrome, except the hypermobility type.
- Imaging studies such as CT scan, MRI, ultrasound, and angiography may be useful in identifying certain features of the condition.
- Urine tests to detect deficiencies in certain enzymes that are important for collagen formation may be helpful in diagnosing kyphoscoliosis type.
