For Trisomy 21, the chance of a positive result being correct ranges from 33 percent to 83 percent. That means you could get a "false positive" result that would be concerning and might lead you to have additional testing. If you get a positive result, however, the accuracy is less reliable. If you get a negative result for these conditions, there's a high likelihood that the test is correct and you can feel fairly confident that you don't need any further testing. For Trisomy 18, the negative result accuracy is 97.7 percent, and for Trisomy 13 it's 96.1 percent. If you get a negative result, there's less than a 1 percent chance that it's incorrect. That said, when testing for the major conditions (see below), the NIPT test is very accurate – especially if you get a negative result.įor example, when testing for Trisomy 21 (Down Syndrome), the negative result accuracy of the test is 99.5 percent. So, a "normal" NIPT result doesn't guarantee a healthy baby, and an "abnormal" result doesn't mean your baby definitely has a certain condition. That means the results don't indicate for sure whether your baby has a chromosomal condition. No, NIPT is a screening test, not a diagnostic test. If you want to know, the test can tell you if you're having a girl or a boy.Results are provided fairly quickly (within a couple of weeks, often sooner).It's available very early in pregnancy, at 9 to 10 weeks pregnant or later.While you'll need follow-up diagnostic testing to confirm results, negative results provide a high degree of accuracy – and reassurance – for a number of conditions.( Amniocentesis and CVS carry a small risk of miscarriage, for example.) It's perfectly safe for you and your baby and carries none of the potential risks of some other testing.There's no need to schedule and take the time for an invasive procedure, like amniocentesis or CVS. A simple blood draw taken at a regular prenatal checkup is all you need. There are some good reasons why it's such a popular test: But the strike could lead to delays in getting appointments and non-urgent procedures being rescheduled.NIPT is a simple procedure that provides a lot of useful information. The company said it was bringing in thousands of temporary workers to fill gaps during the strike. The strikers include licensed vocational nurses, home health aides and ultrasound sonographers, as well as technicians in radiology, X-ray, surgical, pharmacy and emergency departments.ĭoctors are not participating, and Kaiser says its hospitals, including emergency rooms, will remain open during the picketing. The Coalition of Kaiser Permanente Unions, representing about 85,000 of the health system's employees nationally, approved a strike for three days in California, Colorado, Oregon and Washington, and for one day in Virginia and Washington, D.C. The non-profit company, based in Oakland, California, provides health coverage for nearly 13 million people, sending customers to clinics and hospitals it runs or contracts with to provide care. Kaiser Permanente is one of the country's larger insurers and health care system operators, with 39 hospitals nationwide.
