Cord blood banking testing overview
Informed by recognized medical guidance
Overview
Cord blood banking testing is a set of checks done on blood taken from a baby’s umbilical cord just after birth. The blood is then stored (banked) for possible future medical use, such as treating certain blood or immune system conditions. The testing looks for infections, genetic problems, and whether the blood is suitable for transplant.
Key facts
- Cord blood contains special cells called stem cells that can grow into different types of blood cells.
- Testing checks for infections (like hepatitis or HIV), genetic disorders, and the blood type.
- The blood can be stored in a public bank (donated for anyone) or a private bank (kept for your family).
- Cord blood is collected immediately after birth — it does not harm you or your baby.
Cord blood banking is becoming more common, but it is still an optional choice for parents. Many hospitals offer information about it during pregnancy.
Cord blood banking testing affects parents who are considering storing their baby’s cord blood. It is most relevant for families with a known genetic condition or who have a child who might need a stem cell transplant.
Symptoms
- There are no symptoms that require an emergency call related to cord blood banking testing. However, if you or your baby have any medical emergency during or after birth, call your local emergency number immediately.
- ⚠If you have concerns about the collection process or your baby’s health after birth, speak to your midwife or doctor the same day.
Common symptoms
- This test does not have symptoms. It is done on a healthy baby’s cord blood after birth. Parents may consider testing if they have a family history of certain blood or immune disorders.
Symptoms in children
- No symptoms — the testing is done on the cord blood itself, not on the child.
Symptoms in older adults
- Not applicable.
Causes
Main causes
- Cord blood banking testing is not caused by a condition. It is a choice made by parents. Reasons include having a family history of blood cancers, immune deficiencies, metabolic disorders, or other illnesses treatable with stem cells.
Risk factors
- There are no risk factors for the testing itself. But certain genetic conditions may be more common in some families, making stored cord blood more valuable for future treatment.
When to see a doctor
See a doctor urgently if:
- No urgent need related to the testing itself. If you are in labour and have not yet decided about cord blood banking, let your healthcare team know as soon as possible.
Book a routine appointment if:
- Talk to your midwife or doctor during pregnancy (usually at an antenatal appointment) about cord blood banking options. They can explain the testing process and where to get more information.
Diagnosis
This is not a diagnosis — it is a screening and testing process for stored cord blood. The cord blood sample is sent to a laboratory where it is checked for infections (like HIV, hepatitis B and C, syphilis), blood type, and cell count. Genetic testing may also be done if you choose private banking or if there is a family history of certain conditions.
Tests that may be done
- Infectious disease testing (HIV, hepatitis B, hepatitis C, syphilis, etc.)
- Blood type (ABO and Rh)
- Total nucleated cell count (a measure of stem cell quantity)
- Viability testing (checks if stem cells are alive and healthy)
- Genetic testing (only if specifically requested, e.g., for inherited disorders)
What to expect at your appointment
If you choose to bank cord blood, your midwife or doctor will collect it after your baby is born and the cord is cut. The process takes about 10 minutes and is painless. The sample is sent to a cord blood bank, which will test it and store it if it meets safety standards. You will usually get a report with the test results within a few weeks.
Treatment
Cord blood banking testing itself is not a treatment. The stored cord blood may be used in the future as a treatment for certain conditions, such as leukaemia, lymphoma, sickle cell disease, or immune disorders. Treatment involves transplanting the stem cells to help rebuild the patient’s blood and immune system.
Self-care at home
- No self-care is needed for the testing. If you bank cord blood, make sure to follow the instructions provided by your cord blood bank regarding storage and record-keeping.
Medical treatments
If cord blood is used for treatment in the future, it is given as an infusion (drip) into a vein, similar to a blood transfusion. Before the transplant, the recipient may need chemotherapy or radiation to prepare the body. The stem cells then travel to the bone marrow and begin making new healthy blood cells. This is a complex medical procedure that is carried out in a specialist hospital.
When is surgery considered?
Cord blood infusion is not a surgery. It is a transplant procedure. If the stem cells are used to treat a condition, no surgical incision is needed.
Living with this condition
If you choose to bank cord blood, there is no effect on your daily life. The blood is stored for years. You may want to keep the bank’s contact information and your child’s medical records in case the blood is needed later.
Lifestyle tips
- No specific lifestyle changes are required. The decision to bank cord blood is personal. Some families feel reassured knowing the stem cells are available if needed.
Diet and exercise
No changes to diet or exercise are needed for cord blood banking. A healthy lifestyle during pregnancy is always recommended for your overall health and your baby’s health.
Mental health and emotional wellbeing
For some parents, the decision to bank cord blood can bring up feelings of worry about future health problems. It is normal to feel uncertain. Talk to your healthcare provider or a counsellor if you are anxious. Remember that banking is an option, not a necessity.
Prevention
Cord blood banking testing does not prevent any disease. It simply stores stem cells that might be used for future treatment. Some conditions that could be treated with cord blood are not preventable.
Vaccines
Not applicable. But standard vaccinations during pregnancy and for your baby are important for overall health.
Screening programmes
Prenatal screening (during pregnancy) can identify some genetic conditions. Cord blood banking testing is a separate process that happens after birth.
Complications
Long-term outlook
Cord blood banking is a personal choice that can offer hope for future medical treatments. Most people will never need to use their banked cord blood. However, for families with a known genetic condition, it can be a valuable resource. The testing process is reliable and standardised.
