There are two kinds of blood tests for pregnancy tests -- quantitative and qualitative. Assuming you've waited long enough (much less than 49 days), and the test is done properly by the lab, the quantitative test is very accurate. The qualitative blood test is about the same accuracy as urine tests. Even the home urine tests are 97% accurate. So if you took the quantitative blood test you can be very sure it's right. Even with the other tests 97% is pretty accurate. I suspect the error rate in blood labs is greater than that.

No, menstrual blood should not interfere with urine pregnancy test results. The hormone detected in a pregnancy test (hCG) is not present in menstrual blood, so the presence of menstrual blood should not impact the accuracy of the test.
Would a test be accurate during implantation?
Fertilization is when the pregnancy hormone hCG has begun production and this hormone is what is searched for by pregnancy tests (urine and blood). However, this amount can be very little and may be difficult for a urine test to pick up. You can get the best accuracy a few days after your missed period, but they (urine tests) can detect up to 5 days before the first day of your last menstrual period. There is hCG during implantation, so it does have the potential to be detected and accurate, particularly for blood tests which are much more sensitive than urine tests.

How does menopause affect pregnancy test accuracy?
Menopause typically does not affect pregnancy test accuracy, as these tests detect the presence of pregnancy hormones in the urine or blood. However, menopausal women may encounter irregular hormone levels that could potentially cause a false-positive or false-negative result on a pregnancy test. It's recommended to consult a healthcare provider for confirmation if there is uncertainty.
