What's this test for?

This test is ideal if you're experiencing unexplained developmental delays, poor growth, unusual body odors, or recurring metabolic symptoms that suggest your body isn't processing certain building blocks of protein correctly. It's also helpful if you or a family member has a known or suspected inborn metabolic condition and needs ongoing monitoring. Many people use this test to check nutritional status when other explanations for fatigue or growth issues haven't panned out.

What's included in this test?

This test measures a wide panel of individual amino acids in your urine, giving a detailed snapshot of how your body is breaking down and using protein. Grouping these amino acids together helps paint a full picture of metabolic function rather than looking at just one piece, since imbalances often show up across several related compounds at once. This makes it possible to catch patterns tied to rare metabolic conditions as well as general nutritional gaps.

What happens after I get my results?

Your results will show up in your account with each amino acid level explained against its normal range, so you can see clearly which ones fall outside the expected zone. Depending on what's found, next steps might include dietary adjustments, targeted supplementation, or retesting after a few months to track progress. You can download a standard lab report from your account at any time, and the trends feature lets you compare results over time to see if changes are working.

How can I naturally support healthy amino acid metabolism?
Eating a variety of protein sources throughout the day helps your body get a balanced mix of amino acids rather than relying on just one type. Staying well hydrated supports your kidneys in properly filtering and excreting amino acids. Reducing processed foods and increasing whole foods like eggs, fish, legumes, and leafy greens can also support balanced protein metabolism over time.
When will I get my results?
Results are typically ready within about 7 days of your sample being received at the lab. This turnaround allows time for the detailed lab analysis needed to accurately measure the many individual amino acids in your sample. You'll get a notification as soon as your results are posted to your account.
Who should consider this test?
This test is a good fit for people with a family history of metabolic disorders, individuals with unexplained developmental or growth concerns, and those already diagnosed with a metabolic condition who need ongoing monitoring. It can also be useful for anyone wanting a deeper look at their nutritional and protein metabolism status. If you've had puzzling symptoms that haven't been explained by standard testing, this panel can offer more specific answers.
What symptoms indicate I may need this test?
Common signs include poor growth or developmental delays in children, unusual body or urine odors, frequent vomiting or lethargy after eating protein-rich foods, and unexplained muscle weakness. Adults might notice ongoing fatigue, brain fog, or digestive issues that don't have a clear cause. If these symptoms run in your family or have been present since childhood, this test can help identify an underlying metabolic pattern.
What is amino acid metabolism and why does it matter?
Amino acids are the building blocks your body uses to make proteins, muscles, hormones, and even brain chemicals. When your body can't properly process certain amino acids, they can build up to unhealthy levels or become deficient, which can affect growth, energy, and organ function. Understanding your amino acid levels helps identify whether an inherited or acquired metabolic issue might be behind ongoing symptoms.
What does an abnormal amino acid result mean?
A high level of a specific amino acid can mean your body isn't breaking it down efficiently, which is a hallmark of certain inherited metabolic conditions. A low level might point to inadequate protein intake or an issue with absorption. Either pattern is worth following up on with dietary changes, targeted nutrient support, or retesting to see if the pattern persists.
How often should I retest?
If you're monitoring a known metabolic condition, retesting every few months is common to track how well dietary or lifestyle changes are working. If this is a first-time screening and results come back normal, you likely won't need to retest unless new symptoms appear. Your results page will note whether your specific pattern suggests more frequent monitoring.
