The MSAFP test is a simple blood test. A small sample of the mother's blood is drawn, usually from a vein in the arm. The blood sample is then sent to a laboratory, where the AFP levels are measured. The results are typically available within a week. It's important to note that the MSAFP test is a screening test, not a diagnostic test. Abnormal results indicate a need for further testing, such as [ultrasound](https://), [amniocentesis](https://), or [chorionic villus sampling](https://), to confirm the presence of any abnormalities.
