What's this test for?

This test is ideal if you're planning a family and want to know your carrier status for dihydrolipoamide dehydrogenase deficiency (DLDD), especially if you have Ashkenazi Jewish ancestry. It's also useful if you or a family member has unexplained symptoms like poor muscle tone, feeding problems, or lactic acid buildup that could point to a genetic metabolic condition. Many people use this test simply for peace of mind before starting a family.

What's included in this test?

This test looks specifically for two DLD gene changes that together explain most cases of this condition in people of Ashkenazi Jewish background. Screening for these two specific variants matters because it tells you and your partner your chances of passing this rare metabolic disorder on to a child, without needing broader, more expensive genetic testing.

What happens after I get my results?

Your results will show up in your online account along with a plain-language explanation of what a positive or negative carrier result means. If you test positive as a carrier, a practical next step is to have your partner tested too, since the condition only affects a child when both parents pass on a variant. You can download the official lab report anytime from your account, and if you test again in the future for other genetic panels, you'll be able to track your results over time. If a result raises urgent health concerns for a child already showing symptoms, seek medical care right away.

How can I naturally support metabolic health if I'm a carrier?
Being a carrier of a DLD gene variant does not affect your own metabolic health, since carriers typically have no symptoms at all. That said, general habits like eating a balanced diet, staying hydrated, and avoiding excessive fasting support healthy energy metabolism for anyone. If you're planning a pregnancy, focus on getting your partner tested and discussing family planning options based on both results.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your report is available in your secure online account, so there's no need to call and check.
Who should consider this test?
This test is a good fit for couples planning a pregnancy who want to know their genetic carrier status ahead of time, particularly those with Ashkenazi Jewish heritage where these variants are more common. It's also relevant for families with a history of unexplained metabolic or neurological symptoms in infants or young children. Anyone curious about their genetic background related to rare metabolic conditions can also consider it.
What symptoms indicate I may need this test?
In infants, warning signs include poor feeding, low muscle tone, vomiting, slow growth, and unusual sleepiness or lethargy. Older children or affected individuals might show developmental delays, stiffness or spasticity, seizures, or repeated episodes of unexplained illness during infections or fasting. If you've noticed these signs in a child, or if they run in your family history, this test can help identify an underlying genetic cause.
What is DLD deficiency and why does it matter?
DLD deficiency, also called maple syrup urine disease type III, is a rare inherited condition where the body can't properly break down certain proteins and produce energy correctly, leading to a buildup of harmful acids in the blood. It matters because untreated cases can cause serious problems like developmental delays, seizures, and repeated health crises, especially during illness or fasting. Knowing your carrier status ahead of a pregnancy lets you plan and get early testing for a newborn if needed.
What causes DLD deficiency to appear in a child?
A child only develops DLD deficiency if they inherit one altered gene copy from each parent, since it's a recessive condition. If both parents are carriers, each pregnancy has a 25% chance of the child being affected, a 50% chance the child is a carrier like the parents, and a 25% chance the child has no variant at all. This is why testing both partners is such an important step in family planning.
What should I do if my results are abnormal?
If you test positive as a carrier, the most useful next step is to have your partner tested for the same two variants to understand your combined risk for a future child. This information can then guide conversations about family planning options and whether additional prenatal or newborn testing makes sense. There's no need to worry about your own health, since carriers are generally healthy and unaffected.

Negative

What this means

A negative result means neither of the two tested DLD gene variants was found, so your chance of being a carrier for this specific form of DLD deficiency is very low. A positive result would mean you carry one copy of a variant, which typically doesn't cause symptoms but is important for family planning.

* 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.
