Free Beta hCG

FREE BETA HCG Test

This test measures the free beta subunit of human chorionic gonadotropin (hCG) in the blood. hCG is a hormone produced during pregnancy, and its levels change as pregnancy progresses.

This is commonly used as part of first-trimester prenatal screening, particularly in combination with PAPP-A, maternal age, and ultrasound findings such as nuchal translucency (NT). This combined assessment helps estimate the risk of certain chromosomal conditions, including Down syndrome (Trisomy 21) and other chromosomal abnormalities.

The test may also be used in early pregnancy evaluation as advised by a healthcare provider. A free beta hCG result by itself cannot diagnose a chromosomal abnormality or confirm the health of a pregnancy; it must be interpreted as part of the appropriate clinical or screening protocol.

This Test is Recommended for Individuals:

• Pregnant women undergoing first-trimester prenatal screening
• Women undergoing dual marker / double marker screening
• Pregnant individuals having an NT scan as part of combined screening
• Women requiring risk assessment for chromosomal abnormalities
• Individuals undergoing early pregnancy evaluation as advised by their healthcare provider

FAQs

1. What does the Free Beta hCG test measure?
It measures the free beta subunit of hCG in maternal blood. This marker is commonly used in first-trimester prenatal screening.

2. When is Free Beta hCG tested during pregnancy?
It is commonly measured during the first trimester, particularly as part of combined screening around the time of the NT scan. The exact timing depends on the screening protocol and healthcare provider's recommendation.

3. Does a high or low Free Beta hCG result mean the baby has a chromosomal abnormality?
No. An individual Free Beta hCG result does not diagnose a chromosomal condition. It is combined with PAPP-A, maternal age, gestational age, and ultrasound findings to calculate an overall screening risk.
