Father has factor 5 leiden.am due for endovenous laser surgery on saphenous vein for varices under local anaesthetic.should i be tested?is it risky?

No : Does your father have a heterozygous or a homozygous factor v leiden? In the setting of no evidence of thrombosis/blood clots- you do not need to get a factor v leiden check. It is mainly a blood work. Your surgery is only local laser surgery - you should be fine. Post-op you should be able to be back on your feet and walk around again. Do not smoke, be active, avoid being sedentary, exercise.

Not likely: F you father is heterozygous for factor v leiden, you might not even have inherited the gene at all. I agree with dr. Ho, if you have never had a clot yourself, your risk (despite your family history), is extremely low and you shouldn't have to worry unless you have other risk factors like smoking, taking the birth control pill or hormones, and/or are over 45 years of age

Leiden 5: I would discuss this with your md and may be best to be evaluated prior to procedure
