Homocysteine levels are typically measured through a blood test. The normal range for homocysteine is generally between 5 and 15 micromoles per liter (μmol/L). Levels above this range indicate hyperhomocysteinemia, which can be categorized into moderate (15-30 μmol/L), intermediate (30-100 μmol/L), and severe (>100 μmol/L).
