August 11, 2011- Tufts University researchers studied a number of blood tests that are available to people online but are not often used by doctors in the U.S. The study was published Wednesday in the August 10th Journal of the American Medical Association.
Fifty-seven published studies for gender testing were reviewed by the school’s researchers that included over 6,000 pregnancies. Tests that are sold directly to the consumer were not part of the research rather they looked at one called the PCR that can detect genetic material. The woman pricks her finger and sends the blood in to the manufacturer and they in turn send it to a lab.
Their results were that nearly 95% of the time gender predicting is accurate when the woman is at minimum seven weeks pregnant, over a full month prior than any of the other conventional test like ultrasound or amniocentesis. Tests that were done prior to the seven week period using blood or urine were not accurate.
Many researchers are saying this is a break through for women that may have babies that are at risk of hereditary diseases that are sex linked. But concerns were raised about the study in fear that abortions will increase.
