How is an alpha-fetoprotein test performed?
Although the specific details of each procedure vary slightly, generally, an alpha-fetoprotein test follows this process: • Blood is usually drawn from a vein between the 15th and 20th weeks of pregnancy (16th to 18th is ideal). • The blood sample is then sent off for laboratory analysis. • Results are usually available within one to two weeks or less, depending on the laboratory.
