Homocysteine should not be taken on an empty stomach

Homocysteine

is an intermediate product of methionine and cysteine metabolism, which is easily affected by dietary factors. In order to ensure the accuracy of the test, it is necessary to draw blood on an empty stomach. If you eat before the test, it may lead to an increase in the raw materials for synthesizing cysteine, causing an increase in homocysteine indicators, and thus affecting the doctor's judgment of the disease.

The normal value of homocysteine is 5-15μ mol/L. If the index is>15μ mol/L, you should be alert to hyperhomocysteinemia, H-type hypertension, coronary atherosclerotic heart disease and other diseases. Trace element examination, blood pressure measurement, coronary angiography, etc. should be further performed to confirm the diagnosis.
