The price of homocysteine testing ranges from$35-$50, where the price varies slightly between different levels of hospitals. Homocysteine testing is primarily a screening test for stroke, for elevated serum homocysteine, which is also a risk factor for cerebrovascular disease. Homocysteine can usually be measured after blood collection, and the normal value is usually within 20 μmol/L. If a patient has hyperhomocysteinemia, it is recommended that the patient take regular oral folic acid and vitamin B12 to reduce the serum homocysteine level. Patients are also advised to eat more fresh vegetables and fruits, as they contain folic acid and vitamins that can lower serum homocysteine and also fight against atherosclerosis. For serum homocysteine testing, patients are advised to visit a regular hospital for testing. In case of abnormalities, oral medication should be taken under the guidance of a physician.
