Fetal Blood Sampling
Fetal blood sampling is a procedure used to diagnose, treat or monitor various fetal problems. Using a very small needle, specialists in Maternal Fetal Medicine are able to remove a tiny amount of blood from the fetus during pregnancy.
This procedure is performed to:
- Determine blood type
- Diagnose genetic or chromosome abnormalities
- Diagnose possible fetal infections
- Identify possible fetal anemia (low red blood cell count)
- Identify possible low platelet count
How is this procedure performed?
- This procedure is performed using continuous ultrasound guidance to place a needle through the maternal abdomen into a tiny fetal blood vessel.
- A sample of fetal blood can then be sent for testing.
Will I need to have a full bladder?
Sometimes but usually not.
When will I get the results?
Your physician can advise you regarding when to expect the results, as result times do vary depending on the kind of test.
