What sample is required?
The determination is made from a venous blood sample.
Is some kind of prior preparation necessary?

Why do the analysis?
To find out if you have a hereditary mutation in a gene that increases the risk of clot formation, and therefore of deep vein thrombosis (DVT) and/or venous thromboembolism.
When to do the analysis?
A couple of months after having suffered a thrombotic episode or when an anticoagulant treatment with heparin does not respond adequately.
