Examinations and Tests
Because an attack of
Raynaud's phenomenon ends quickly, your health
professional most often will determine whether you have Raynaud's phenomenon by
your description of your symptoms. Your health professional will review your medical
history, perform a physical examination, and do blood tests or other tests to rule
out a secondary cause of Raynaud's phenomenon. If possible, you may want to
take a colour photograph of your hands when you are having
symptoms to bring to your appointment.
A
rheumatologist or
dermatologist may examine the small blood vessels
(capillaries) at the base of your fingernails using a small magnifying lens.
Known as "capillaroscopy," this simple examination may help distinguish between
primary Raynaud's and secondary Raynaud's that is part of a connective tissue
disease such as
lupus,
scleroderma, or
rheumatoid arthritis.
