How long does a pregnancy blood test take to show positive?
It takes 3 or 4 days after implantation for sufficient hormone to be produced, so wait until 14 days or so after sex to do a pregnancy test.
Implantation bleeding can happen when the egg implants in the uterine wall. It is not something that happens in every case. You can have implantation bleeding and NOT be pregnant as well, because the blastocyte may have genetic abnormalities that do not permit growth, thus the egg dies.
Ideally you should wait until your period is late, that would assure a most accurate test, that being said, the stress of not knowing can sometimes get to you, there are certain tests on the market that allow you to test up to 4 days before your period is due, but if you get a negative, there still is a chance you may be pregnant and it's just too early to tell..

Cramp is when your muscles tighten and go stiff it will hurt but will go off some time after. Sometimes if you get cramp in your foot you wil be able to see it just stand on it and it will go off. Some people say that cramp is caused by not enough water but i dont believe that . It could be caused by low calcium levels in the blood.
Human chorionic gonadotropin is produced by the what gland?
placenta.
Human chorionic gonadotropin is produced by the placenta. During the first few weeks of pregnancy, the kidneys excrete large amounts of the hormone in the urine. Pregnancy kits test for this hormone in the urine to confirm an early pregnancy.
Can you still be pregnant if hcg levels drop?
Alot of reasons can cause that. You could be pregnant and not know and having a miscarriage! Take a blood pregnancy test asap!
How soon can pregnancy show positive in a blood test?
Hiya! A increase in HCG through a blood test can be detected by a Quantitative blood test, 42 hours after being previously tested.
Yes, I have. I was 7 weeks and 5 days pregnant when that started. I was told by my doctor that it was likely old blood that was being discarded and that it was nothing to worry about. In my heart this didn't feel right so I requested a sonogram. Sadly, the sonogram revealed that the pregnancy failed (there was no heart beat). So, for me, the spotting and mucus which was accompanied by mild cramping was a sign that my uterus was trying to abort the pregnancy.
Is a hcg level of 84 884 normal for seven weeks pregnant?
Every person HGC level is good... for an estimate of what you should be at every week please refer to this website which has a lot of good information in it.

Can an ovarian cyst cause a negative blood pregnancy test?
Ovarian cycts have absolutely no affect on pregnancy test. The test is simply measuring your HCG Titers, which is your hormone levels. When you are not pregnant this measurement is 0. During pregnancy, the numbers get well over the 1000s. Cysts do not release any hormones into your body. http://www.i-am-pregnant.com/encyclopedia/H/HCG/
What does it mean if the clear blue easy digital test says nothing but 'see leaflet'?
This can happen when you have too much urine on the test or test may be bad I would retest.
If you feel a knot in your tummy are you pregnant?
Well obviously you havent missed a period. I thought all of this too but i am now pregnant and know a lot more. No, just because it is hard around there doesnt mean you could be pregnant. It is more likely your muscles. When you first become pregnant, by the 4th week the only thing that is hard is a little spot right above your pubic bone.
What does it mean when the lines on a pregnancy test is faint?
Any time there is a line where the positive line should be, no matter how faint, is regarded as a positive result. It can be faint because the hCG levels are very low if taken very early in pregnancy or if the baby is not producing adequate levels.
ok, first of all there shouldn't be a negative line unless you bought a digital test. if there are two lines you are pregnant, one window just says the test worked the only reason any kind of line came up in the other window is becasue you are pregnant....hope this helped
Yes you can be pregnant. ASk for an ultrasound scan.
Can you have an accurate HIV test after 8 days?
Answer
HIV Duo Testing (ELISA IV), which detects the HIV-1-P24 antigen -- a definitive precursor of HIV -- has a superb success rate at as little as 7 days. However, a 28-day test is recommended, and apparently produces a higher degree of accuracy. Answer
HIV Duo detects both antibodies to HIV as well as p24, which is part of the virus itself. Antibodies are only formed after exposure to the antigen, so the antigen is detectable earlier than antibodies. This test reduces the window period significantly, and as the previous answer said, has a good sensitivity at even 7 days.
However, we must remember that each individual is different, and may "incubate" the virus for a different time to other people. In any particular individual, 4th generation ELISAs such as the Duo will only pick up antigen 7-10 days before the antibody appears. So those who would become positive on an antibody-only assay at 8 weeks will become positive on the Duo at 6.5-7 weeks. HIV first has to replicate locally before it spreads to the lymph nodes, and only after that does the major viraemia appear, and it is that viraemia that is detected by the p24 part of the assay. If the local replication occurs quickly, the person will be positive sooner.
There will always be the very small percentage who take longer.
There is one pont which is not logical.
So those who would become positive on an antibody-only assay at 8 weeks will become positive on the Duo at 6.5-7 weeks.
The antibody production is the host response to the antigen there may be differences in the time period of host response so it would be wrong to conclude the presence of antigen relative to antibody production.assume A and B are infected (read antigen present at point t(time)) A takes x period to seroconvert(antibody production) and B takes Y period to seroconvert.but both had antigen at t(time) hence it would be wrong to assume presence of antigen in A as x-c and B as Y-c (c is a constant). both would be different.

Can you be pregnant even if the pregnancy test says no?
Yes, it is possible. Wait a few days from the last time you took a test and best to use first morning urine, and if still negative but you think you still could be pregnant or haven't gotten your period yet, then go ahead and see a doctor. That is the best way to determine. They will take blood tests from you to.
Where does a doctor press on your stomach to tell if your pregnant?
The Dr is probably checking what is called your fundal height. Fundal height is determined by the size of the uterus to determine fetal growth and development. The Dr could also be checking the position of the baby if you are getting close to delivery.
Can you still have more than one period in early pregnancy?
Sometimes it is commen for women to have periods during pregnancy.
But, any kind of bleeding during a pregnancy should be reported to your doctor so they can check just in case to make sure that there was no miscarriage.
Is it possible that you are pregnant if you have had a positive HPT but a second test was negative?

How soon can you detect pregnancy?

A test that measure the hormone levels in the blood plasma?
test used to measure the levels of hormones in the blood plasma
What can make a pregnancy test read a false positive?
There are a few factors that can result in a false positive. Most of the time though false positives are rare! I recently experienced this. I have 4 children and have never had a false positive! My test never showed up unless I was pregnant. I recently had 5 tests show a faint positive and went to the doctor for blood test which was negative. I was told that a cyst on your ovaries can sometimes make a test appear positive (false positive). Other factors include chemical pregnancy. This is one where everything develops as though you are pregnant, except for the baby. If you are on any medication that contains the pregnancy hormone (HCG), this also can make your test turn up positive. It is best to have a blood test done by the doctor to totally insure you are not pregnant.
What is more serious getting a false negative or a false positive?
Positive = You really did it.
False Positive = The test said you did it, but you really did not.
