What's this test for?

This test is ideal if there's a concern that a newborn may have been exposed to opioids before birth. It confirms whether specific opioids like codeine, morphine, hydrocodone, hydromorphone, or oxycodone were present during pregnancy by analyzing the baby's first stool (meconium). It's often used when maternal drug history is unclear or when a newborn shows signs that could be related to opioid withdrawal.

How should I prepare for this test?

How can meconium naturally clear opioid traces over time? Meconium itself isn't something you can influence once formed, since it accumulates passively during the last trimester of pregnancy. The best way to support a newborn's recovery from opioid exposure is calm, low-stimulation care, frequent small feedings, skin-to-skin contact, and close monitoring for withdrawal signs. Reducing or stopping opioid use during pregnancy under proper guidance is the only way to lower the amount that accumulates in meconium.

What's included in this test?

This panel checks meconium for five specific opioids and their metabolites using a highly accurate lab method called gas chromatography/mass spectrometry. Testing multiple opioids matters because each one can come from different sources (prescription pain medication, illicit drug use, or breastfeeding exposure), and identifying the specific substance helps guide appropriate newborn care. Note that this test does not detect fentanyl, so a negative result doesn't rule out fentanyl exposure.

What happens after I get my results?

Your results will appear in your account, with each opioid listed along with its cutoff value so you can see exactly what a positive or negative result means. If any opioid is detected at or above the cutoff, the next step is typically closer monitoring of the newborn for withdrawal symptoms and follow-up care planning. A downloadable lab report is available in your account for your records, and you can revisit results anytime, though this is typically a one-time confirmatory test rather than one you'd track over time.

When will I get my results?

Results are typically ready within about 7 days of the lab receiving the meconium sample. Because this test uses a detailed confirmatory method, it takes a bit longer than a basic screening test, but it provides more definitive answers about which specific opioids were present.

Who should consider this test?

This test is generally considered for newborns when there's reason to suspect opioid exposure during pregnancy, such as unclear or inconsistent maternal drug history, or when a baby shows symptoms suggestive of withdrawal. It may also be used when the American Academy of Pediatrics guidance recommends meconium testing over urine or umbilical cord samples due to its ability to reflect exposure over a longer window.

What symptoms indicate I may need this test?

In newborns, signs like excessive crying, trouble feeding, tremors, poor sleep, sweating, or difficulty being consoled can be linked to neonatal opioid withdrawal syndrome. Low birthweight or preterm birth combined with a known or suspected history of maternal opioid use are also reasons this test might be recommended. These symptoms alone don't confirm exposure, which is why lab confirmation through meconium testing is useful.

What does a positive result mean?

A positive result means the specific opioid was found in the meconium at or above the cutoff level, confirming that the baby was exposed to that opioid before birth. This information helps guide appropriate monitoring and supportive care for the newborn since symptoms of withdrawal can vary depending on which opioid was involved. It should always be considered alongside the family history and physical exam findings for the fullest picture.

What does a negative result mean?

A negative result means none of the tested opioids were found above the cutoff level in the meconium sample. However, a negative result does not completely rule out in utero opioid exposure, since how often the opioid was used during pregnancy can affect whether it shows up in meconium. This test also doesn't screen for fentanyl, so a negative result doesn't rule out exposure to that specific drug.

What should happen if results are abnormal?

If an opioid is confirmed in the meconium, the next step is typically close monitoring of the newborn for withdrawal symptoms like tremors, feeding difficulty, or excessive irritability. Supportive care such as swaddling, dim lighting, frequent small feeds, and skin-to-skin contact can help manage mild symptoms. If withdrawal symptoms become severe, such as continuous vomiting, high fever, or seizures, seek medical care right away.
