What's this test for?

This test is ideal if you're experiencing unexplained developmental delays, unusual fatigue, or metabolic symptoms that suggest your body isn't processing certain nutrients normally. It's also useful if you or a family member have a history of inherited metabolic conditions and need to track how well a treatment plan or diet is working. Many people use this test to get a clearer picture of their overall nutritional and metabolic status.

What's included in this test?

This test measures a broad panel of individual amino acids in your blood plasma, giving a detailed snapshot of how your body is building and breaking down proteins. Looking at the full pattern of amino acids helps identify imbalances that single markers might miss, which is especially useful for catching rare metabolic issues early or confirming that a nutrition or treatment plan is working as intended.

What happens after I get my results?

Your results will show up in your account with each amino acid level explained alongside its normal range, so you can see exactly where you stand. If any values fall outside the expected range, the report offers simple next steps, such as dietary adjustments or a recommended retest schedule to keep monitoring your levels. You can download a standard lab report directly from your account at any time, and the trends feature lets you compare results over multiple tests to see how your levels change.

How can I naturally support healthy amino acid balance?
Eating a variety of protein sources like eggs, fish, beans, and dairy helps ensure you get a full range of amino acids your body needs. Staying well hydrated and eating regular, balanced meals also supports steady amino acid levels throughout the day. If you follow a restricted diet, such as vegan or low-protein, paying extra attention to combining plant proteins can help fill in any gaps.
When will I get my results?
Results are typically ready within about 7 days of your sample being tested. This slightly longer turnaround reflects the detailed lab analysis needed to measure the many individual amino acids included in this panel. You'll receive a notification as soon as your results are available in your account.
Who should consider this test?
This test is a good fit for people with a personal or family history of inherited metabolic disorders, or anyone already being monitored for a condition affecting protein metabolism. It's also useful for those wanting a deeper look at their nutritional status beyond a standard blood panel. Parents tracking a child's growth and development concerns may also find this test helpful.
What symptoms indicate I may need this test?
Symptoms like unexplained tiredness, muscle weakness, slow growth in children, or unusual reactions to certain foods can all be reasons to consider this test. Some people notice a distinct odor in their sweat or urine, which can also be linked to amino acid imbalances. If you have a family history of metabolic conditions, even mild or vague symptoms are worth checking out.
What does a high amino acid result mean?
A high level of a specific amino acid can mean your body isn't breaking it down properly, which sometimes points to an inherited metabolic condition. It can also simply reflect a very high-protein diet or certain supplements you're taking. The report explains which amino acids are elevated and offers practical next steps, like adjusting your diet or considering a retest.
What does a low amino acid result mean?
A low level of an amino acid may mean your diet isn't providing enough protein, or that your body is using it up faster than usual due to stress, illness, or intense physical activity. It can also point to how well your body absorbs nutrients. Adding more varied protein sources to your meals is often a simple first step, along with retesting to track improvement.
How often should I retest?
If you're monitoring a known metabolic condition or an ongoing treatment plan, retesting every few months is a common approach to track progress. If you're testing simply to check your nutritional status with no known issues, retesting once a year is usually enough unless your results or symptoms change. The trends feature in your account makes it easy to see these changes over time.

Demo results
Low Normal (0.6-1.5 mg/dL) High

What this means

This result shows phenylalanine slightly above the typical range, which can happen with a high-protein diet or may point to a metabolic issue that affects how your body processes this amino acid. On its own, a mild elevation isn't usually a cause for alarm, but a pattern of elevated results deserves closer attention. The full amino acid panel helps put this single result into context.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
