If there are no associated injuries to other parts of your knee, the signs and symptoms of a posterior cruciate ligament injury can be so mild that you might not notice that anything's wrong. Over time, the pain might worsen and your knee might feel more unstable.
Expecting parents can use NIPT as a blood test to determine gender of their baby. However, this non-invasive test is used to test chromosomal conditions such as Down's syndrome. It is usually done at 10 weeks of pregnancy. NIPT is 92%-99% accurate in detecting chromosomal conditions.
Pregnancy test accuracy is typically expressed in terms of percentages. For example, the pregnancy tests sold at Early-Pregnancy-Tests.com have a stated accuracy level that exceeds 99.9%. This means that the pregnancy tests will correctly yield a positive result 99.9% of the time when immersed in a sample containing 20 miu/ml or greater of the hormone Human Chorionic Gonadotropin (hcg). The accuracy of most brands of pregnancy tests, generally speaking, tends to be around the 99% mark. These tests are calibrated such that a faint test line will be visible at 20 miu/ml hcg, while no test line should be visible at lower levels.
