Methionine Quantitative Plasma

Methionine Quantitative Plasma is a laboratory test that measures the amount of methionine in your blood.

• Methionine Quantitative Plasma is used to diagnose and monitor methioninemia, an inherited metabolic disorder that prevents your body from breaking down methionine properly.
• It can also help evaluate other metabolic disorders or inborn errors of metabolism.

Your doctor may recommend this test if:

• You or your child has symptoms or risk factors for methioninemia, such as developmental delays, seizures, or a family history of the condition.
• You have symptoms of other metabolic disorders or inborn errors of metabolism.

Elevated levels may indicate methioninemia, while low levels may indicate a deficiency in methionine or vitamin B12/folate or liver disease.

The test involves drawing a small amount of blood from a vein in your arm. 

No special preparations (like fasting) are required before Methionine Quantitative Plasma. However, inform your doctor about any medications or supplements that you are taking as they may affect the test results. It is advisable to consult your healthcare provider to determine if there are any particular requirements you should be aware of.

Your doctor may order other tests such as urine organic acid assay, plasma amino acid test, or molecular genetic testing. These tests can help diagnose and monitor several inherited metabolic disorders, including methioninemia.

Plasma Methionine Test or Methionine Blood Test

Methioninemia is an inherited metabolic disorder that prevents your body from breaking down methionine properly. This leads to elevated levels of methionine in the blood, which can cause developmental delays, seizures, and other health problems.
