There are several ways to test for Dupuytren's contracture. A doctor can observe and feel the hands themselves or have the patient do a tabletop test: the individual lays their hand palm down on a table. Inability to fully flatten the fingers, along with the characteristic knots and thickened cords, are strongly suggestive of Dupuytren's contracture. Some people may also require genetic testing, which has confirmation benefits over the tabletop test but also limitations and risks.
