No data for homocysteine screening

A Canadian physician recommends screening for homocysteine. There is no data to support this recommendation:

While screening for hyperhomocysteinemia itself is not difficult, a benefit from lowering the homocysteine concentration on cardiovascular and venous thromboembolic disease remains unproven. Thus, even if we identify patients with an elevated homocysteine concentration it is not clear that acting on this information is of benefit.
