Methionine
Methionine from blood (measured value)
A test for methionine in the blood can be useful to identify certain disorders or metabolic problems. Methionine is an essential amino acid involved in several biochemical processes in the body.
Here are some reasons why this test can be done:
- Diagnosis of amino acid metabolism disorders: An elevated level of methionine in the urine may indicate a disorder of amino acid metabolism, such as cystathioninuria, homocystinuria, or methioninuria. These disorders are often hereditary and lead to abnormally high levels of methionine in the body.
- Monitoring liver disease: Elevated levels of methionine in the urine may be associated with liver disease because the liver is involved in the regulation of amino acids, including methionine.
- Monitoring treatments: For patients already diagnosed with amino acid metabolism disorders, the test can be used to monitor the effectiveness of treatments and dietary interventions.
- Dietary assessment: In some cases, the test can be used to assess whether the diet contains enough methionine. Dietary methionine deficiency can lead to health problems.
Methionine in blood is usually targeted to specific medical situations; this test is not routinely performed in healthy individuals. If you think you have a reason to have this test done, discuss it with a doctor. A doctor can determine if the test is appropriate based on your symptoms, medical history and family history, and can take appropriate steps to evaluate and diagnose possible conditions.
