The doctor will take a medical history and perform a physical examination.
Medical history questions may include:
- Have any other family members been born with extra fingers or toes?
- Is there a known family history of any of the disorders that can be associated with polydactyly?
- What other symptoms or abnormalities are also present?
Physical examination:
An infant with polydactyly may have other symptoms and signs that, when taken together, define a specific syndrome or condition. Diagnosis of that condition will be based on a family history, medical history, and thorough physical evaluation.
Diagnostic tests:
Laboratory studies such as chromosome studies, enzyme assays, x-rays, and metabolic studies may be done to confirm a suspected disorder.
After seeing your health care provider:
You may want to add a note to your personal medical record indicating that polydactyly was present, any diagnosis related to it, and any treatment done.
Prenatal diagnosis may involve ultrasound or more-advanced embryofetoscopy during the first trimester.
