Lysine Quantitative Plasma Test

The Lysine Quantitative Plasma test measures the amount of lysine, an amino acid, present in your blood.

The Lysine Quantitative Plasma test is mainly done to

• Detect inherited metabolic disorders or inborn errors of metabolism.
• Monitor the effectiveness of treatment for such conditions.
• Establish a provisional diagnosis based on the clinical history and suspected symptoms.
• Evaluate lysine supplementation and medication recommendations.

Your doctor might recommend this test if

• You have symptoms suggestive of metabolic disorders or inborn errors of metabolism.
• You have a family history or genetic risk factors for such conditions.
• You are undergoing treatment that could affect lysine levels.

Elevated levels may indicate the presence of metabolic disorders or kidney disease, while low levels may indicate lysine deficiencies or malnutrition. 

A sample of your blood will be collected by a healthcare professional using a needle and a syringe. 

To prepare for the test, follow any fasting recommendations provided by your doctor. You should also inform them about any supplements or medications you are currently taking that could affect lysine levels. It is advisable to consult your healthcare provider to determine if there are any particular requirements you should be aware of.

Other tests that may be ordered alongside this test include urinary amino acid analysis, urine organic acid analysis, and blood chemistry tests like liver and kidney function tests.

Lysine quantitation test

Inherited metabolic disorders or inborn errors of metabolism are genetic conditions that affect how the body processes and converts food into energy. These conditions can lead to abnormal levels of amino acids, sugars, and other substances in the blood and urine, causing various health problems.
