Baby and Co 4D is proud to now offer SneakPeek Gender Determination as early as seven weeks. The test is done in our studio by a phlebotomist who will draw a sample of your blood for the test. For the test to be accurate, you must be at least seven weeks along. We do this testing Tuesday through Friday. Call us at 937-524-5414 to arrange an appointment – we do not yet have a way to place an appointment on line.
