Methionine-to-Sulfur Ratio
MET / SULF
Description
"Methionine-to-Sulfur Ratio" test measures the balance between methionine, an essential amino acid, and sulfur metabolites that play a role in methylation and detoxification. Doctors may recommend it when metabolic dysfunction, fatigue, or liver strain is suspected. An imbalanced ratio may indicate disrupted methylation, poor nutrient processing, or sulfur metabolism issues. A blood sample is used to assess this balance. Results help guide targeted care through dietary changes, supplements, or deeper metabolic testing to restore function and energy.

Results That Differ From The Norm (Direct and Indirect Causes)
Increased levels may indicate:
Amino acid (sulfur) supplementation
Cystathionine beta-synthase deficiency (Genetic disorder affecting methionine metabolism)
Homocystinuria (Genetic disorder resulting in elevated homocysteine and methionine levels)
Kidney dysfunction
Methionine adenosyltransferase deficiency (Deficiency in the enzyme responsible for met...
Key Reasons For Testing
Assessment of Sulfur Amino Acid Metabolism: Evaluates the balance between methionine, cysteine, and other sulfur-containing compounds.
Diagnosis of Sulfur Metabolism Disorders: Detects conditions like homocystinuria and cystathionine beta-synthase deficiency.
Newborn Screening: Identifies inherited metabolic disorders early for timely intervention.
Assessment of Liver Function: Reflects alterations in liver health through sulfur metabolism.
Evaluation of Nutritional Status: Assesses dietary intake and metabolism of sulfur amino acids.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
