Optimal Result: 0 - 2 mmol/mol creatinine.

2-Oxo-4-methylthiobutanoic acid, also known as 4-(methylsulfanyl)-2-oxobutanoate or 2-keto-4-methylthiobutyrate, belongs to the class of organic compounds known as thia fatty acids. Thia substituted fatty acids are saturated fatty acids which are modified by insertion of a sulfur atom at specific positions in the carbon backbone.

What does it mean if your 2-Oxo-4-methiolbutyric result is too high?

- High 2-Oxo-4-methiolbutyric acid may be due to an error in methionine metabolism.

- Confirmation of the genetic disorder requires testing of plasma amino acids.
