Yes, it can depend on whether your urine was diluted from drinking a lot of fluids or which type of test you take. The more expensive ones can detect early pregnancy. Here is some info on why there is a difference in the tests. Check with the manufacturer on their sensitivity levels.
The sensitivity of a pregnancy test determines how soon after conception pregnancy can be detected by the diagnostic kit. Concentrations of hCG are reported in milliInternational Units (mIU) or amounts equal to 1/1000th of an IU per milliliter. Pregnancy tests with a sensitivity of 20 mIU/ml are more sensitive than tests with 50 to 100 mIU/ml. With 20 - 25 mIU/ml tests, high sensitivity equates to early detection of pregnancy. That means you can begin testing accurately as early as eight days after conception. Conception may take place several days after date of intercourse, so the date of intercourse should not be viewed as the necessary day of conception.
No , but a negative test can be a false positive .
This happened to me when I got pregnant with my third child. The first test was negative and the second positive. From what I understand, a pregnancy test can give a false negative but rarely gives a false positive.
Yes
If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.
No, if you're having a miscarriage, the pregnancy test will still be positive as you're passing the pregnancy.
Pink- Positive Blue-Negative
a negative pregnancy test can be wrong because it could have misditected, a positive pregnany can't be wrong though.
Depends...
There is no false positive pregnancy test result. If it has ever been positive, then it is positive.
It means you had a miscarriage.
A positive answer on a home pregnancy test means that you are pregnant and should see a Dr. A negative answer means that you are not pregnant. If you get a negative response and feel that it is in error you should wait two days and test again or see your Dr.
Only if the test is defective or you took the test incorectly.
