False Pregnancy Test

no prednisone is a steriod that does not interfere with pregnancy tests.

I think it depends on how early you are in pregnancy. I took 10tests which all were negative even though I knew I am pregnant before the HgC levels were high enough to indicate pregnancy via test. You can usually get an accurate reading about 1-2weeks pregnant with a good test such as Clearblue digital (I used this which indicated I was 1-2weeks pregnant) and I'm not 4weeks pregnant and registered with the midwife. Good luck!

There are several gunpowder contaminants such as the fertilizer, detergent, match head, even soil and cigarettes. They contain nitrates which gives similar result to gunpowder residues when treated with Diphenylamine (DPA) Reagent.However, their reaction differ from gunpowder nitrates from the characteristics of the specks as well as the distribution of the specks. Usually a gunpowder contaminants will show a smear of blue color .

i was always told you will know when your pregnant, and it was about 6 days before i was even supposed to miss my period and i just had a feeling so i took a home preg. test, knowing it was too early, and it came back positive, with a very very faint line. about 3 weeks later i took another and it was clearly positive so i went to the dr and am 9 weeks pregnant now. so i believe it can be up to a week b4 u miss your period for some people, maybe not all. but if its coming up positive, you probably are prego

No. If you think you may be pregnant and your home test says different; trust your body. A doctor will do a blood test which will not only show right away; a 'quantitative' test can tell the level of hcG, telling about how long since you conceived. Which can be double checked with an ultrasound if necessary.

In very early pregnancy, yes. The reason it is recommended to take the test in the morning is because the hCG levels are more concentrated in the urine then, and can be more readily detected. So if it is in the first weeks of pregnancy, the level can go undetected.

yes. some pregnancy test show up negative, even though you are pregnant. I have the SAME problem with the EXACT same symptoms. I hope someone answers your question because I need help on this one too :(

The first three months while your baby is busy developing

Results are not considered accurate after that amount of time has elapsed. After 10 minutes it is said to disregard all results. If you still think you could be pregnant, then take another one in 3 days preferably with your first morning urine.

There are several things that can contribute to a negative pregnancy test even if you are pregnant. Some medications can give you a false negative, the timing of the test can affect the results. If you did not follow directions properly; if you let the test sit for too long the results may read negative after a while. It is important to read the results within the amount of time given on the instructions of that particular pregnancy test you bought. To ensure the best results: * Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1-2 days before expected period. Although some test say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low. * urinate for as long as possible on the foam-like strip * wait for the results!

Yes you can. I'm 18 and 3 months pregnant. I was starting off with my regular periods but, out of the blue my periods just stopped for 6 months I took a home pregnancy test(hpt) it came out negative. So I went to the doctor to get a blood test done and found out I was 3 MONTHS PREGO I asked my doctor why did I have a negative result and it was because my hcg levels were not high enough for the hpt to detect the pregnancy. So the answer to your question is yes you can be pregnant

If you deliver a diluted sample, they'll flunk you just for the dilution.

Perform another pregnancy test

that happened to me i took a pregnancy test 2 weeks or maybe 3 after unprotected sex when i first took the test just one line popped up then when i went back it was faintly positive then maybe a week after my late period i started bleeding very heavily and took 3 more test and they where all negative and when i went to my docter i found out i miscarried == == Unfortunately if you test very early you can get a positive hpt then bleed very heavy cause the egg did not take then you can get a neg. cause the baby is no longer there. That is the reason why most doctors do not like to test early. This has happened to a lot of women when they didn't even know it cause they get there period like normal.

If you are 42 days late, but a home test is still showing negative - and I assume the test has been taken at least twice - then it might be appropriate to consult with your doctor, but wait till day 44 (one month past last period plus two weeks) and test again.

Of course, if you are of an age where menopause is likely, this may not be a concern. But if not, then you should see your doctor.

Promethazine (Phenagren) can cause a false negative.

You would have extremely bad lower abdominal cramps. The ones you can't walk with. If you are pregnant now and are concerned tell your doctor. Your tubes can burst and get an infection following it.

Further to this- 5 women in the UK die every year from missed ectopic. Also, you will most like have prune- juice like bleeding- dark and syrupy. Treatment is either a shot or surgery which may lead to the loss of the affected tube.

I would say u r pregnant. I took 3 hpt's & went to my doc. within that hour & their test were neg. I am 6 months pregnant now. You can get false neg. for a lot of reasons. Mine was because I wasn't even late for my period yet & I sat in the doctors office drinking 2 cups of water which deluted my urine so the hormone wasn't detected. Later I took 11 more hpt's & all faint pos. All were first response.

Defanitly. not all pregnancy tests are valid. it could be because of the experasion date, if yu take the test to early before ur missed period, if yu pee to much or not enough. If yu take more then one test and they all come out faint i advise yu to take a free walk in pregnancy test at a clinic just to be safe.

Absolutely not!

No u cant reuse a preganancy test

pregnancy tests are only 99% accurate. this means that there is still a possibilty that it is incorrect. although it is highly unlikely that you are pregant if you tested negative three times, it still might be a good idea to see your doctor and have him/her test you for pregnancy if you have missed your periods and are suffering from any pregnancy symptoms such as spotting blood, breast tenderness, morning sickness, nausea or bloating. but i wouldn't worry too much if the only reason you think you may be pregnant is just because you have missed a few periods. this is not unusual and is quite common amongst teens and women. either way, a visit to your doctor should put your mind at ease.

Do a home pregnancy test (maybe not at home if you are trying to avoid your parents finding out for now!!) But to make sure it is as accurate as possible be sure to use your morning urine if possible. Whatever you do don't drink a tone of fluids just so you can urinate to do the test. That will dilute your urine and can cause a false reading. Also, wait until you are at least 1-2 days before your expected period. If it comes up positive, you may feel the need to do a couple of more though your outcome probably won't change. If you feel you are pregnant and it gives you a negative reading try another one because a womans hCG levels (the pregnancy hormone) double every two days. There are a few contributing factors that can give you a false pregnancy test reading negative when you really are pregnant (medications, timing of the test, etc.). If they are all positive you are going to have to tell your parents eventually but to help you out you might want to remain calm and to keep your parents calm you might want to say something like this "Look, mom, dad I know you had big plans for me and wanted me to grow up with certain expectations but I have made some mistakes in my life and I need you to be supportive about this." Then announce in whatever fashion you wish that you are pregnant then add, " but I don't need you to be angry about this, at least if you are going to be angry please don't be angry while around me. I realize I may have made a mistake or I at least wasn't ready for this yet. But if all I feel is anger from you and the family that is probably going to cause some resentment from me toward my baby. And I don't want that. Everything is going to be okay, even though I don't know exactly how yet. Just please be supportive of this. I am going to be receiving enough punishment from myself just going through highschool being pregnant and all of my plans being changed; I really don't need the added stress from you guys."

I know this is probably a bit more answer that you were looking for

I don't think that is something that it has been shown to do. You should be aware, though, that if you are pregnant that you should stop taking Topomax immediately. The manufacturers of Topomax are currently involved in a number of class action lawsuits regarding birth defects in babies whose mothers took the drug.

False negatives are usually caused by testing too early. Either you are testing too soon before your period is due, or you had an irratic cycle and ovulated late and it's just too early to pick up the pregnancy hormone. Some women online have taken multiple tests and gotten negatives, then later got a positive.. it was just too early.
