Homocysteine 17.5 umol/L suggests mild hyperhomocysteinemia. The more widely recognized normal fasting value is 5 to 15.9 μmol/L, with a value higher than 15.9 μmol/L defined as hyperhomocysteinemia. A test of 17.5 umol/L suggests a mildly elevated value, which is diagnostic of hyperhomocysteinemia and requires prompt treatment. There is no specific treatment for hyperhomocysteinemia. It is recommended to eat a light diet, not to eat excessively greasy, high-fat food, and to reduce the intake of animal protein.
