Quizplus · Accepted Answer

Homocysteine and methylmalonic acid levels are commonly used to assess risk for blood clots and stroke. High levels of these substances can indicate an increased risk for cardiovascular disease. HVA and 5-HIAA are metabolites of dopamine and serotonin, respectively, and are not typically used for assessing cardiovascular risk. Hexosaminidase A and B are enzymes used in the diagnosis of Tay-Sachs disease and are not related to cardiovascular risk.
