Yes, it is possible to get a blood test at around 8 weeks of pregnancy to determine the baby's gender. This type of test is commonly known as non-invasive prenatal testing (NIPT) or cell-free DNA testing. To obtain this test, you will need to consult with your healthcare provider who will guide you through the process. The NIPT analyzes fetal DNA present in the mother's blood and can provide accurate results regarding the baby's gender. However, it is important to note that no medical test is 100% accurate, and there may be a small margin for error. As for insurance coverage, it varies depending on your specific policy and provider. It is recommended to check with your insurance company beforehand to understand if they cover this type of testing and what costs may be involved.
