Welcome to Koala Labs!

Welcome to Koala Labs, led by consultant sonologist and obstetrician Dr. John D. Stephens. Located in Blaine, Washington, our office is limited to prenatal diagnosis using ultrasound imaging and screenings. At Koala Labs, we can help you find the answers to two important questions. Is my baby healthy and is it a boy or a girl?

We utilize the latest, cutting-edge technology to evaluate the health of your unborn baby in the first trimester. We offer a procedure, known as Fetal Anatomic Sex Assignment or FASASM, to determine the sex of a fetus with 100% accuracy by ultrasound in the 12th week of pregnancy. Dr. Stephens developed this patented technique. We also offer Ultra-Screen®, which is a non-invasive test used to determine the likelihood that a baby will have Down syndrome, trisomy 18 or other chromosomal abnormalities.

We welcome you to learn more about Koala Labs in Blaine, WA. Please contact us for more information.
