Answer 1

Women receiving hCG therapy to treat a luteal phase defect or other fertility problem should consult their doctor as to accuracy of home pregnancy tests

Answer 2

Yes, the tests can be wrong for many reasons, most common, human error when doing test.

Here is info on the 2 most common tests.

What's the difference between pregnancy tests that check urine and those that test blood? Which one is better?
There are two types of pregnancy tests. One tests the blood for the pregnancy hormone, hCG. The other checks the urine for this hormone. You can do a urine test at home with a home pregnancy test. You need to see a doctor to have blood tests.

These days, most women first use home pregnancy tests (HPT) to find out if they are pregnant. HPTs are inexpensive, private, and easy to use. Urine tests will be able to tell if you're pregnant about 2 weeks after ovulation. Some more sensitive urine tests claim that they can tell if you are pregnant as early as one day after a missed period.

If a HPT says you are pregnant, you should call your doctor right away. You doctor can use a more sensitive test along with a pelvic exam to tell for sure if you're pregnant. Seeing your doctor early on in your pregnancy will help you and your baby stay healthy.

Doctors use two types of blood tests to check for pregnancy. Blood tests can pick up hCG earlier in a pregnancy than urine tests can. Blood tests can tell if you are pregnant about 6 to 8 days after you ovulate (or release an egg from an ovary). A quantitative blood test (or the beta hCG test) measures the exact amount of hCG in your blood. So it can find even tiny amounts of hCG. This makes it very accurate. Qualitative hCG blood tests just check to see if the pregnancy hormone is present or not. So it gives a yes or no answer. The qualitative hCG blood test is about as accurate as a urine test.

Answer 3

Most likely, it is right, but there is always that like 1% chance that it can be wrong. At the doctors, they would probably run a blood test on you, and if you get a positive, they will go by your last period to tell how far along you are.

Answer 4

Once you get a positive result on a home pregnancy test, you should call your ob/gyn (or your GP) and tell them about it.

With most of my pregnancies, the doctor's office took a positive home test as proof that I was pregnant. They will still run a pregnancy test when they send you for your prenatal blood work, just to confirm the pregnancy and to get your HCG levels.

They will ask you when your last period started, and determine how far along you are according to that date.

Good luck and congratulations!

Answer 5

It could be what they call a false-positive however those are fairly rare. If you received a positive result it is best to assume that it is correct and make a followup appointment with your doctor. This is in the best interest of both you and the baby. The doctor should be able to tell you and estimated date after asking you some questions.

Answer 6

Pregnancy tests generally don't give false positives (ie telling you that you are pregnant when you're not) because they test for a hormone which is usually only produced if you are pregnant. You're due date can be worked out by counting 40 weeks from the date of the first day of your last period.

Answer 7

well if a home test gives u positive it might be wrong cause for the lack of menstruation the hormones rises but if u made a blood test then the positive answer its definely right, if u go to the doctor they do tell u how far is ur preagnancy, hope i had been of help to u

Answer 8

Positive preg results happen within 9-12 days after conception. If you get a true positive (i.e. Bright line) then seeing your doc for a quantative beta would be the next step.

Answer 9

I've seen alot of false negatives, but never a false positive unless it's an old test or you're looking at the results after 10 mins.

Answer 10

Is highly unlikely that the test is wrong, but you can ask your dr to confirm it anyway. Length of pregnancy is taken from the first day of your last period (even though you prolly didnt fall pregnant till around 2 weeks after). They can get a slightly more accurate gage of the babies age in terms of its developent n measurements so far when you have a scan later in the pregnancy.

Answer 11

You will never ever ever get a false positive -- and a doctor can only tell you how far ALONG you are by testing the hormone level in your blood, or by doing an early ultrasound.
