Description
The homocysteine test measures blood levels to assess cardiovascular and neurological health risks, especially for patients with family history, vitamin B12/folate deficiency, or recurrent clotting—costs ¥7–30 at partner hospitals in China, with ChinaMedicalHub coordinating booking and interpreter support.
Main Uses
Homocysteine testing is primarily used to assess the risk of cardiovascular diseases, including heart attack and stroke. It is also useful in diagnosing and monitoring treatment for vitamin B12 or folate deficiencies, and in evaluating patients with unexplained blood clots, especially in younger individuals.
Normal Range
The normal range for homocysteine levels in the blood is typically between 5 to 15 micromoles per liter (μmol/L).
Low Values - Possible Causes
Low homocysteine levels are less common and usually not a significant health concern. However, they can be associated with: excessive intake of folic acid or vitamin B12, certain genetic mutations, or over-supplementation.
High Values - Possible Causes
High homocysteine levels, known as hyperhomocysteinemia, can be caused by: deficiency in vitamins B6, B12, or folic acid, kidney disease, thyroid disorders, psoriasis, or genetic factors such as MTHFR gene mutation.
