What is homocysteine called?

Homocysteine has no other name.

Homocysteine is a sulfur-containing amino acid that is an intermediate in methionine and cysteine metabolism. The normal range is 5-15μmol/L. If a patient has a lower homocysteine level than normal, it is usually not clinically significant. If homocysteine levels are higher than normal, it may be related to physiological factors such as smoking, drinking alcohol, eating foods rich in methionine, etc. It may also be caused by disease factors, such as hypothyroidism, psoriasis, cerebral infarction, acute lymphoblastic leukemia, etc.

For patients with abnormal homocysteine test results, it is necessary to further combine other tests to clarify the cause, such as physical examination, thyroid function test, tumor marker test, CT examination, etc.
