Serum homocysteine 44 micromol/liter is abnormal and higher than normal, which is hyperhomocysteinemia, a risk factor for cardiovascular and cerebrovascular diseases, dementia, and other diseases. Normal values for serum homocysteine are 5 to 15 micromoles/liter. Homocysteine is metabolized in the body through two pathways: methylation and transsulfuration. Problems in these two pathways affect homocysteine methylation and transsulfuration, resulting in homocysteine accumulation and elevated values, which can damage cells, tissues and organs. Hyperhomocysteinemia is an independent risk factor for many chronic diseases, which include cardiovascular and cerebrovascular diseases such as hypertension, stroke, and coronary atherosclerotic heart disease, but also diseases such as dementia and chronic kidney disease. In conclusion, if the test suggests a serum homocysteine of 44 micromoles/liter, it is recommended to follow medical advice for further consultation.
