Pregnancy Tests

No. An hpt is 99% accurate when the is result is positive and roughly 50% when negative. The reason for this disparity between a false negative and false positive is in the early days of pregnancy, the hormone an HPT tests for maybe too low for a positive result. That is why the tests says it should not be taken sooner then four days before your expected period. The closer you are to your period, the more accurate the results. Once you missed your period, a negative and positive test are on par in terms of accuracy. For instance, if a test is negative a week after your expected period, chances are you are not pregnant. If you have not had your period for three months, you would have just ended your first tri-mester and therefore your hormones will would be at a very comfortably level of detection. Chances are you have not gotten your period because of stress, being over/underwieght, of changes in what you eat or your amount of excercise. There are a multitude of other explanations so go see your doctor to find out why.

It depends on the pricing system. They can be more expensive in some clinics. However the quantitative is 100% accurate compared to the qualiative. **********************************************************

Momoftwo0506: It Really Depends On The Type Of Blood Test It Is I Guess I Am Going To Have One Done Today And It Only Cost $19.00 So I Guess It Really Depends On The Place You Go And The Type Of Test You Get.

Wait a full missed cycle. I know the test kits tell you that they can give a reading in 2 days, but the hormone they test for takes a cycle to build up and you are apt to get a false reading with an eariler test. Save your money and do it after you have missed one cycle.
14 weeks after intercourse is the most accurate date for determining pregnancy with a home pregnancy test.

Ironically, the Walmart cheapies -- Equate brand. It identified my pregnancy four days before my period was due. (A faint line, but definitely a line.)

I have read on other site that one week is necessary.

When I got my tubes tied my doc warned me about getting tubal pregnancies. You might want to check it out. It could just be the fact that you got your tubes tied. My periods haven't been the same since I got mine tied. yes, i had my tubal and 4 months later my period was 2 months late...i had negative tests...i went to the dr and he said that it was normal, but if it goes beyond 2 months and you are having symptoms, then tests needed to be ran or medication to start your period..he said that even if you have a tubal pregnancy, that you will most likely have a positive test..

You might be pregnant.
if you only recently started your period, that could be a reason, as you may be experiencing irregular periods. i started mine in august '09, and i didn't have one at all in september. i hope this helped :)
pregnancy, diet, stress, other underling medical conditions, see ur gp for peace of mind
There are very few reasons; the most common one is being pregnant.
You could be pregnant. Or your body could just be changing causing your period to be missed.
Irregular periods, recently stopping or stopped taking birth control, recently took the morning after pill, illness, stress, underlying medical conditions, hormonal imbalance and pregnancy.

Home pregnancy tests are quite accurate. If anything, they give false negatives because it might not have picked up enough of the pregnancy hormone but positives are usually accurate. If you want to be absolutely sure, take another test and if that one too says you are pregnant, count on it.

most are 99%

Depends on the technology used. DNA sequencing for forensic or paternity, or bone marrow transplant can take at least 24 hours for just the testing, then the data is checked and rechecked by several scientists. Then the report is sent . all this can take an additional 2 weeks depending on the workload as some if it is batched with other samples. Lower technology DNA testing for simple disease association or solid organ transplants can take as little as 6 hours, but again, is batched with other samples, and reviewed several times before release, so maybe a week for that testing. All this varies by the lab, and workload.

Yes, ectopic pregnancy is a rare effect of having a tubal ligation. If you've had a tubal ligation and begin experiencing single sided pain, spotting, bleeding or dizziness you need to be evaluated for tubal pregnancy immediately.

The Titanic sunk around 1912, about 98 years ago.

Yes. The embryo may not attach until the 2nd day of your missed period. The hormone that pregnancy tests look for is not evident until the embryo has attached. Which means that you may be pregnant and reciving a false neg. result. I would try again a few days after your missed period.

My doctor told me that can happen, but it can also be a false-positive. He explained that to me that every month when you ovulate, your body gears up to be pregnant, feels like it is, and that's when you can get the false positives. Then, you either become pregnant, or you have your period, that's why he said to wait until you ACTUALLy are late to take a test.

if you go to the dmv to take the test you can get it right then

but if you take the test online you have to wait 24 hours

Yes but it's risky for the pregnancy.

Prenatal testing involves risk and is discouraged for the sole reason of determining paternity because of an increased risk of miscarriage.

The result is considerable variability in the amount of mutated mtDNA molecules that each of the offspring inherits

Consistently

Home pt tests have a time window. If 10 min is still within the window on your particular test then your result is valid. You can always take a second test to be sure.

you work out the date of the first day of period and count how many weeks its been since then, that's how far you will be or use a due date calculator.

To read test strips, first ensure you follow the instructions provided with the specific test. Generally, you dip the strip into the sample (like urine or blood) and wait for the designated time, usually a few seconds to minutes. After waiting, compare the color changes on the strip to the color chart included with the test kit, which indicates the presence or concentration of the substance being tested. Make sure to read the results in natural light for the most accurate interpretation.

This might mean that you have very low estrogen fluid in your body right now, because your so early in your pregnancy. Yes, if i was you i would take another test in about a week.

http://www.intmed.mcw.edu/clincalc/pregnancy.html I went to the above website put in July 18th as your due date. So your light period was probably implantation bleeding, some women will have light spotting when there period would be due when they are pregnant. Also that website goes by a 28 day cycle, So if your cycle is more or less you can add or subtract how many ever days you need to get to your cycle lenth.

Why dont you see your OBGY consultant?

It takes the average couple 8,5 months to get pregnant so the odds are you are not pregnant. Being anxious and waiting for your period can make it skip.
