Does staying up late affect homocysteine test?

Stay up late generally does not affect homocysteine test.

Homocysteine is a sulfur-containing amino acid, which is an intermediate product of cysteine and methionine metabolism. Stay up late generally does not affect cysteine and methionine metabolism, and does not affect homocysteine levels in the blood. Therefore, homocysteine test can usually be done after staying up late.

Although staying up late does not affect homocysteine test results, it is not recommended to stay up late for a long time, so as not to cause immune decline and induce endocrine disorders.
