Pregnancy tests are used to determine amount of Human Chorionic Gonadotropin or hCG that circulates all throughout the woman’s body. To ensure precise results, women should opt for the most accurate tests.
What are the Most Accurate Pregnancy Tests?
- Quantitative blood a test is considered the most accurate test since particular amount of beta hCG is properly determined. This can be observed over time to figure out if pregnancy is healthy or if miscarriage can possibly occur.
- The qualitative urine and blood tests detect whether Human Chorionic Gonadotropin is present or not based on the cut-off value for sensitivity of the tests. There are tests that are ultimately sensitive and might detect hCG level as low as 5mlU/ml. Some other tests are less sensitive and cannot detect pregnancy until the level reaches 25mlU/ml or even greater.
- The home pregnancy tests work by means of binding hCG in woman’s urine to antibody. Antibody is said to be anti-hCG and binds to hormone. This is also coupled with blue or pink eye indicator and as urine moves up into the membrane, this crosses two lines.
- The first line is the test line with antibody anchored into the test membrane and the second line is the control line that contains antibody into the dye. This is actually an indicator that the pregnancy test functioned properly. If control lines do not appear, then the pregnancy test is invalid.
If women have hCG bound into the antibody, this will bind antibody on test line and color will start to develop. If there’s insufficient or no hCG at all in the urine, antibody tend to wash over test lines and dye will adhere to regulate the line. Color will not develop on test line in the second situation.
When Should You Take Pregnancy Test?
Many types of pregnancy tests guarantee to be precise as early as the main day of missed period or even before. You’re probably going to get more precise outcomes but in the event that you hold up until after the very first day of missed period or better yet a week after the missed period.
So, why wait? Soon after the fertilized egg connects into your uterine lining known as implantation, placenta will then structure and create the hormone Human Chorionic Gonadotropin or HCG. This hormone enters your urine and bloodstream.
During the early pregnancy, HCG concentration increases quickly-multiplying every two to three days. The earlier you take the pregnancy test, the harder it may be for the test to identify HCG.
Remember that the right ovulation timing may change among ladies or even from one month to another and fertilized egg can embed into the uterus at various period of time.
This can influence the time when HCG production starts and ends up noticeable.
It is vital to confirm pregnancy immediately and depending on how far you are in your pregnancy, your healthcare provider may suggest that you have an ultrasound or repeat a urine test in the doctor’s facility or have your blood tested to properly measure your Human Chorionic Gonadotropin or hCG.
