In most cases, home antigen tests or self-tests - the kind sold over the counter - are your best option. As antigen tests have become widely available, it’s easier and faster to get test results at home. “While vaccination remains the best way to combat severe illness from COVID-19, testing is the most important tool to prevent the spread of the virus right now,” said Craig Robbins, MD, physician co-lead for Kaiser Permanente’s national COVID-19 vaccination program. “Testing quickly identifies someone who is infected so they can stay home and prevent further transmission.” Home antigen tests are appropriate for most situationsĮarly in the COVID-19 pandemic, PCR lab tests were almost always used to detect the virus. Taking a home antigen test is the quickest and easiest way to put your mind at ease and make sure, if you are infected, you’re not putting others at risk by spreading the virus that causes COVID-19. Your blood sample or the extracted DNA samples will not be used for any other purpose.You wake up feeling sniffly, and your throat is scratchy. There will be no further clinical testing on this blood and your blood sample will be discarded once we have confirmed the results with you. The laboratory will extract cell-free DNA from your blood and carry out the NIPT on the cell-free DNA. We will send your blood sample along with your personal information (including name, date of birth, gestational age) to a company called TDL Genetics, which is based in London, United Kingdom. Who carries out the analysis of your blood for the NIPT? If your pregnancy is 11 +4 weeks or more you can have a nuchal scan (11 +4 -13 +6 weeks), or a mini-anomaly scan (14-19 weeks), or an anomaly scan (19-24 weeks) or a wellbeing scan along with a NIPT on the same appointment for a total cost of £500.If your pregnancy is less than 11 +4 weeks you can have a viability scan and NIPT from 10 weeks at a total cost of £400.It is therefore advisable that you still have ultrasound scans at 11-13 weeks and at 20-22 weeks to examine the fetal anatomy and at 30-32 weeks to examine the fetal growth. The NIPT does not provide information on physical defects, such as heart or brain abnormalities and spina bifida, or fetal growth.If the scan at 11-13 weeks shows a high nuchal translucency (more than 3.5 mm) or major defects, such as exomphalos, holoprosencephaly, heart abnormalities or megacysis, the chance for some rare chromosomal conditions may be high. In such cases you may choose to have CVS or amnio. The NIPT does not provide information on other rare chromosomal abnormalities.If the NIPT shows that there is a low chance (less than 1 in 10,000) that the baby has trisomy 21 or 18 or 13 it is unlikely that the baby has one of these conditions.If you want to be certain if the baby has one of these conditions you should have CVS or amnio. If the NIPT shows that there is a high chance that the baby has trisomy 21 or 18 or 13 it does not mean that the baby definitely has one of these conditions.If you want you can have the test repeated (at no cost) and there is a 65% chance that the test will give a result. This is due to technical problems with the analysis of the sample and does not suggest that there is a problem with the baby. In about 2% of cases the test does not give a result.The results from the test will generally be available within 4 business days and we will notify you as soon as we receive them by phone and email/letter.When do I expect to get the NIPT results?
