Threonine Quantitative Urine Test

The Threonine Quantitative Urine Test measures the amount of threonine in your newborn's urine sample.

• To identify metabolic disorders that affect the threonine pathway • To detect inborn errors of metabolism • To detect vitamin B6 insufficiency

• If your doctor suspects any metabolic disorder or inborn errors of metabolism, they may order this test. Common indications include muscle weakness, developmental delay, or liver disease. • Newborns are also tested to detect metabolic disorders that can cause serious health problems early on.

Elevated levels may indicate metabolic disorders such as liver disease, multiple sclerosis, or even cancer. Low levels could indicate malnutrition or digestive issues.

• Provide a 10-ml spot urine sample of your newborn. • The sample will be taken to a laboratory for testing.

• Follow the fasting recommendations of your doctor. • Stop amino acid supplementation or medication for some time before the test. • Inform your doctor if you have any specific requirements.

Other tests that may be ordered alongside the Threonine Quantitative Urine Test include complete blood count, liver function tests, and other urine organic acid tests.
