The Free Beta HCG Serum test is typically recommended as part of prenatal screening for pregnant individuals, especially those at increased risk of chromosomal abnormalities in the fetus. This may include pregnant women over 35 years old, those with a personal or family history of chromosomal abnormalities, or individuals with abnormal results from other prenatal screening tests. Ultimately, the decision to undergo the test should be made in consultation with a healthcare provider based on individual circumstances and preferences.
