What's this test for?

This test is ideal if you or your child are experiencing developmental delays, feeding difficulties, or physical features that may point to a metabolic or genetic condition. It's also useful during pregnancy planning or after a family history of Smith-Lemli-Opitz syndrome has been identified. The test looks at cholesterol production in the body, which can be disrupted in this condition.

What's included in this test?

This test measures a compound related to cholesterol production in the body. Because cholesterol is essential for healthy cell growth, brain development, and hormone function, checking this marker can help identify a metabolic issue tied to Smith-Lemli-Opitz syndrome.

What happens after I get my results?

Your results will show up in your online account with each value's normal range clearly explained. If your result falls outside the expected range, the report will walk you through what that means and suggest reasonable next steps, including whether retesting or further evaluation makes sense. You can download a standard lab report anytime from your account, and if you test again down the road, our trends feature lets you compare results side by side.

How can I naturally support healthy cholesterol production?

Eating a balanced diet with healthy fats, like avocados, nuts, and olive oil, gives your body the raw materials it needs to build cholesterol naturally. Staying hydrated and getting regular movement also supports overall metabolic function. That said, Smith-Lemli-Opitz syndrome is a genetic condition, so lifestyle changes alone won't fix an underlying enzyme problem — this test is meant to help identify whether that's happening.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. You'll get a notification as soon as your report is available in your account, so there's no need to keep checking back manually.

Who should consider this test?

This test is a good option for parents concerned about a child's growth or development, adults with unexplained symptoms linked to cholesterol metabolism, or anyone who has a close family member diagnosed with Smith-Lemli-Opitz syndrome. It's also commonly considered during prenatal planning when there's a known family history.

What symptoms indicate I may need this test?

Signs that may point to a need for this test include slow growth, feeding problems in infants, distinctive facial features, or developmental delays. In adults or during family planning, a known genetic history of the condition is often the main reason to test. If you're noticing several of these signs together, it's worth checking your cholesterol-related markers.

What is cholesterol synthesis and why does it matter?

Cholesterol synthesis is the process your body uses to build cholesterol, which your cells need to grow, repair themselves, and produce certain hormones. When this process doesn't work properly, it can affect brain development and physical growth, especially in children. That's why checking this marker can be so useful for catching issues early.

How often should I retest?

Retesting isn't usually needed on a regular schedule for this particular test since it's typically used to answer a specific health question rather than track ongoing levels. If your first result is unclear or borderline, your report may suggest a repeat test to confirm the finding. Otherwise, retesting is generally guided by new symptoms or family planning needs.

What should I do if my results are abnormal?

If your results come back outside the normal range, start by reading through the explanation in your report to understand what the number means for you. Consider genetic counseling resources or additional testing to get a fuller picture, especially if you're planning a pregnancy or evaluating a child's symptoms. If symptoms are severe, such as significant feeding difficulty or failure to thrive in an infant, seek medical care promptly.
