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.
Ultrasound is a good alternative test for blood test to determine gender because it is safe and accurate in determining baby sex. What's more, it can also detect defects such as heart defects, cleft palate, and club foot that other tests fail to detect.
