I tested positive for pregnancy. A quantitative hCG test at 3w6d since LMP showed a level of 40. 5 days later my hCG was 120. Is this increase too low?

Quantitative Hcg (Definition)

A qualitative pregnancy test tells you either yes or no. It can be by blood or urine. A quantitative HCG measures the exact amount of the pregnancy hormone that is present in the blood test and is useful in a few ways. A number that doubles every 48 hours means a normal pregnancy - less may mean a tubal pregnancy. The value may also give an indication of how far ...Read more

Biochemical Pregnanc: If the test was positive and now lower, it is likely you had a biochemical pregnancy. This may mean that the pregnancy was not normal and would not result in you having a baby. Your body eliminated the tissue. This happens more often than we realize. Still, if it happens to you on more than 2 occasions, it suggests that there may be something else going on and you should talk to your doctor. ...Read more

If embryo isn't connected to maternal blood supply until 7days post conception, this would mean hCG isn't yet produced for a urine pregnancy test?

If embryo isn't connected to maternal blood supply until 7days post conception, this would mean hCG isn't yet produced for a urine pregnancy test?

No: The embryo can produce HCG as early as 5 days post fertilization but the amounts are so small and the maternal-fetal blood connections are so minimal that not even a blood test can pick it up, let along a urine pg test that is not positive until your HCG levels are 20 iu/ml or more. You should, however, be able to pick up HCG in a blood test as early as day 9 post ovulation but the levels are low. ...Read more

I had a quantitative hCG test done and my results were <1. What does that mean? I had it done 3 weeks and 2 days after intercourse.

I had a quantitative hCG test done and my results were <1. What does that mean? I had it done 3 weeks and 2 days after intercourse.

U r NOT pregnant: This long after intercourse the ball of cells would have implanted in the uterine wall and have been pumping out ever increasing amounts of human chorionic gonadotrophin. The fact that the assay could not even detect even 1 unit implies that you have no functioning placenta growing - i.e. no pregnancy! ...Read more

Need to repeat: Had you been pregnant with a healthy embryo, HCG level would have increased two fold over two days. It would be prudent to repeat the HCG levels. If you get abdominal pain, go to the emergency room of a hospital to rule out ectopic pregnancy. ...Read more

Took hCG pregnancy test one day before period due and came out negative. Can I trust this result.....

Took hCG pregnancy test one day before period due and came out negative. Can I trust this result.....

Too soon: Nope. You wasted the money on the test. It is negative, but because you had not missed a period yet, and if your period does not start you will have to retest. Wait a few days. If the period does not start then retest. ...Read more

Is it true that pregnancy results depend on the level of hCG being detected on a pregnancy test. Can the level be so low that doctors draw blood?

Is it true that pregnancy results depend on the level of hCG being detected on a pregnancy test. Can the level be so low that doctors draw blood?

Yes, most pregnancy: Tests depend on the detection of a certain level of HCG in the blood. It takes about a week after fertilization (sex that results in pregnancy) for any pregnancy test to be positive (even the blood test). After that time, the blood test will reliably detect pregnancy, and after 2-4 days the urine dipstick test will reliably detect pregnancy. ...Read more

I got a? on a first response pregnancy test. Does that mean there is still hcg present but not enough for a positive result?

I got a? on a first response pregnancy test. Does that mean there is still hcg present but not enough for a positive result?

Mommy, AreWeThereYet?: Maybe it means that you are pregnant and the baby has a question for you. Or, according to their instructions, it means there was an error in the test and that they want you to do the test again. Tests of various kinds often have to be repeated for that reason, a glitch in the mechanics of the test, or a faulty sample. But I kinda like the first idea. Think about what questions your baby might ask you ...Read more
