Because of this taking multiple tests to check the color of the line is not a reliable means of monitoring the development of early pregnancy.
Early detection pregnancy test faint line.
20 miu tests will display a faint line when when hcg levels are at 20 miu while less sensitive tests will display a negative result.
Less sensitive urine tests and qualitative blood tests may not.
Easy home ovulation pregnancy strips.
In early pregnancy hcg levels rise exponentially and you will be likely to see a faint positive grow bolder in a matter of a few days.
2 low test sensitivity thresholds.
First response early result pregnancy test.
Even though you will likely pass more hcg in your urine as the pregnancy progresses a home test will not necessarily reveal a darker line hour by hour or day by day.
Most early result pregnancy tests can only detect hcg when it rises.
The simplest way is to hold and wait for another day or two.
So an extremely faint line on pregnancy test means you are just a few days away from getting pregnant.
Different tests detect hcg at different levels from 20miu to 100miu or more.
Hcg levels rise exponentially in the first two months of pregnancy so the earlier the test is performed the higher the chance of a false negative result.
The reason you would see a faint line on a pregnancy test is that the hcg level is probably very close to the sensitivity threshold of the test.
Whether you re looking for early pregnancy detection or an inexpensive option here are the best pregnancy tests of 2020.
Unfortunately a faint positive line can also be a sign of a very early miscarriage sometimes called a chemical pregnancy which occurs within the first 12 weeks of a pregnancy often much earlier.
Some very sensitive pregnancy test kits can detect pregnancy as early as 6 days before your missed period 5 days before you expect your period however the levels of hcg this early are so low that you can expect any line to be faint.
A false negative pregnancy test usually happens when testing is done too early and you are pregnant but you test negative.
