GENERAL INFORMATION:
What is this test?
This test evaluates blood in a newborn baby's stool or emesis (vomit). It is used to determine if the newborn baby is bleeding (fetal blood), or if the blood came from the baby's mother (maternal blood).
Why do I need this test?
Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:
- Perinatal gastrointestinal hemorrhage
How should I get ready for the test?
Stool:
Before the sample is collected, tell the healthcare worker if your newborn has a medical condition or is receiving medicine that may cause a bloody stool.
Vomit:
Ask the healthcare worker for information about how to prepare for this test.
How is the test done?
A sample of your newborn's stool or vomit is collected and sent to a lab for tests. A blood-stained diaper also may be used for this test.
Stool:
For a stool sample collected at home, place the newborn's stool into a container provided by the healthcare worker. Collect the largest amount of stool possible for the test. Avoid getting urine, water, tissues, or toilet paper in the sample.
Vomit:
Methods used to obtain a sample for this test vary. Ask the healthcare worker for information about how a sample is obtained for this test.
How will the test feel?
The amount of discomfort your newborn will feel depends on many factors, including your newborn's sensitivity to pain.
What should I do after the test?
Stool or vomit should be tested within 30 minutes after it is collected, or as soon as possible.
Stool:
If you collect your newborn's stool, close the container if it has a lid. Follow the healthcare worker's instruction about where to place the container. Clean your hands with soap and water. If you have been asked to collect the stool sample while at home, follow the directions provided.
Vomit:
There are no special instructions to follow after this test.
CARE AGREEMENT:
You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
