I found it on a Planned Parenthood Page. :)
How accurate are pregnancy tests after abortion?
The pregnancy hormone, HCG (human chorionic gonadatropin), can remain in the body for up to 60 days after an abortion. Similarly, HCG levels can be measurable for weeks after childbirth. This can lead to pregnancy tests with false positive results.
Women who are concerned about the accuracy of pregnancy tests during the weeks after abortion may want to take a few tests a few days apart. That can help them see if the levels of HCG are increasing or decreasing. Women who use home pregnancy tests and who are still concerned that pregnancy is continuing or another pregnancy has occurred can consult their clinicians to test for the precise levels of HCG. After at least two tests, the clinician will be able to tell whether the HCG is rising � a continuing or new pregnancy � or whether it is falling � no pregnancy.

No pregnancy test can detect pregnancy that early. It takesabout 2 weeks for your body to produce the hormone that would test you as positive.
Attempting to manipulate a pregnancy test to produce a false positive result is dishonest and can have serious consequences. It is important to use a pregnancy test as directed and to seek medical guidance for accurate results.
A pregnancy test can show a positive result if you have miscarried. There is still enough hormone in your body to produce a positive result.
It means that there is a trace amout of the pregnancy hormone in your urine and you are in fact pregnant. There are, in a few cases, what is called a chemical pregnancy where you will produce the hormone from a fertilized egg that never implants and doesn't actully lead to conception, but still reads as a positive due to trace hGc in your urine stream. It is still however a positive and you should make a call to your OBGYN.
Yes, home pregnancy tests can produce both false positives and false negatives. If a home pregnancy test is positive, you should see a gynecologist to have the pregnancy confirmed as soon as you can.
It is possible for a spayed dog to produce milk. This is a phenomenon that is known as false pregnancy.
Pregnancy tests aren't 100% accurate. Some brands will show a positive reading after 10 mins even if you aren't, so it is important to always read the test when the instructions for the test say to. I don't trust pregnancy tests now as I did 6 pregnancy test and only one showed a positive result, even the test at the dr showed negative and after doing 2 bloodtests over 2 days did i know that i was in fact pregnant and yet i was 6 wks.Pregnancy tests test the pregnancy hormone level in your urine. It is very important to look at the instructions on the box, and read the test when it says to read it.For some women, they don't produce enough hormone for the test to register that they are in fact pregnant. A false positive is a very rare occurrence, however.Chances are, if you got a positive, then yes, you're probably pregnant.
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/
A home pregnancy test can not detect an ectopic pregnancy. If you have gotten a postitive pregnancy test here is what you need to do.IF YOU DO EXPECT YOU DO HAVE AN ECOTOPIC PREGNANCY YOU SHOULD GET LOOKED AT AS SOON AS POSSIBLE. Possible complications are- Loss of embryo, Infertility and serious cases death this happens when the fallopen tube the embryo is in ruptures from the growing embryo and it can be a very serious risk to your health. -Go to your family doctor or nearest walk in clinic and get a refferal to get a blood test to confirm pregnancy - you should also ask for a refferal for an ultrasound to check how far along you are.***(THRU AN ULTRASOUND THEY CAN DETECT AN ECOTPIC PREGNANCY)*** consider all your options if you are pregnant -keeping the pregnancy -abortion(must be 6 to 8 weeks to have an abortion) In Canada they will not preform abortions after 16 weeks however in the States I believe they will do them up to 21 weeks. I personally do not believe in abortion I'm just trying to inform you to make your own decision. -adoption -once results are in ask your family doctor or doctor you are currently seeing if he can refer you to an obctetrician (get on thiss there is a huge baby boom right now and if you want a doctor with you thru out your pregnancy to monitor you and your baby there can be long waiting lists depending on your location) hope this is helpful best of luck
can levothyroxine produce hcg hormone or give a false positive pregnancy result
Yes, a very faint line on a pregnancy test can indicate pregnancy. If the test is taken early, the hCG levels may be too low to produce a dark line. As pregnancy progresses, hCG levels increase, and test lines typically become darker.
Usually around week 24 of pregnancy.
