Can you get a negative HPT but positive blood test?

As with urine/home pregnancy tests, it is possible to end up with false results (both negative and positive) from a blood pregnancy test. A false negative (test is negative, but you’re pregnant) can occur if the blood pregnancy test was performed too early.

Can a HPT be negative and still be pregnant?

The simple answer is yes, you could still be pregnant even with a negative test, depending on when you took it, but there are also other reasons your period could be late. A pregnancy test detects HCG levels in your urine which increase the longer you are pregnant.

Why is my home pregnancy test positive and doctors negative?

The hook effect happens when you have too much hCG in your blood or urine. How is this possible? Well, the high levels of hCG overwhelm the pregnancy test and it doesn’t bond with them correctly or at all. Rather than two lines saying positive, you get one line that incorrectly says negative.

What is the longest hCG can show?

With most current pregnancy test kits, hCG can be detected in the urine as early as 3-4 days after implantation, though it often takes longer. If you are pregnant, on the day you miss your period about 74% of HPTs will be positive.

Can you be 7 weeks pregnant with a negative test?

Sometimes a test can also return a false positive result, detecting pregnancy where none exists, but false negative results are much more common, with as many as 9 out of 15 women testing negative until seven or eight weeks.

What is the longest it can take for hCG to show up?

A pregnancy test can usually detect hCG levels within 10 days of a missed period. Some tests can detect hCG even earlier, within a week of conception, but no test is 100% accurate.

Can it take up to 6 weeks to get a positive pregnancy test?

Depending on a woman’s cycle, a blood test can detect pregnancy between 6 and 14 days after conception and is considered by doctors to be 99% accurate.
