Is homocysteine 12.2 considered high?

Homocysteine 12.2μmol/L is generally not high.

If normal people check homocysteine in blood under fasting conditions, and do not suffer from pyelonephritis, glomerulonephritis and other kidney diseases, kidney metabolic function is normal, the normal value of the test result is 5-15μmol/L, the above value belongs to the normal value, so it is usually not high. However, if homocysteine exceeds 15μmol/L, the patient should immediately inform the doctor, so as not to cause this value to rise all the time, increase the risk of thrombosis, easily block blood vessels, induce coronary atherosclerotic heart disease, acute myocardial infarction and other diseases.
