The Normal Range for Homocysteine Levels



Many of you have written about the homocysteine eAlert sent on May 18th and wanted to know what the normal range for homocysteine levels is. According to HSI panelist Allan Spreen, M.D., there is some disagreement within the medical community regarding what’s considered normal. But as a generally accepted guide, homocysteine levels between 5 and 15 micromoles per liter are considered by many labs as normal. Spreen points out, however, that reports in medical journals such as “Circulation” and the “American Journal of Epidemiology” suggest that risk for disease increases sharply at even lower levels – around 6.3 to 7.0 micromoles per liter. And, your risk can continue to increase as you approach 15.
