Yes: Raynaud's syndrome is "secondary raynaud's", meaning that another medical condition is causing the raynaud's [henomenon. A primary care or rheumatology doctor can order blood tests and other tests to look for the cause. Raynaud's phenomenon is the vasospasm symptom itself, leading to cold, whitish fingers and toes due to decrease in blood flow (a blood test is not needed to verify the symptom).

No: Cold testing usually shows it.
There are some folks with sevondary raynaud's and blood testing may confirm the underlying arthritis, lupus etc.

No: In fact, I wouldn't bother. Some physicians run an anti-nuclear antibody in the hopes that if it's negative, the person won't sit up worrying about scleroderma / CREST. It's not a guide to treatment.

Is there a blood test to confirm raynauds disease?

No: Though many people with raynaud's have a positive ANA (antinuclear antibody), there is no blood test to confirm the diagnosis. However, your doctor should test for associated diseases such as scleroderma. Raynaud's can exist by itself or be associated with other conditions.
