Pregnancy Blood Test
When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks.

Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Yes: Both tests check to see whether the pregnancy hormone, known as HCG (human chorionic gonadotropin) is present. The qualitative HCG simply gives a result as to whether any HCG is present or not. The quantitative HCG test actually measures the level of the HCG in the blood. This can be helpful in diagnosis of abnormal pregnancies such as ectopic, molar, or miscarriage. ...Read moreSee 1 more doctor answer
Testing: You are asking the wrong question. HCG increases daily after a viable pregnancy is old enough to be big enough to have blood and chemicals. That transition occurs at about ten days post conception. It also corresponds with the time a period is due and it stops the period leading to a missed period and the first real symptom of early pregnancy. That is the sign to look for to know when to test. ...Read more
Yes: Blood tests can be done soon after conception (8-9 days after). It's best to wait until after your first missed period to test with he urine pregnancy tests.

I took a pregnancy blood test last week it came out positive, then this week redid another blood test it came out negative why.
Pregnancy blood test came back at 25 mi/mu. What does that mean? How far along is that. Was told negative then said to be postitive. Which is it?
It is positive: Blood pregnancy tests ( HCG level) can detect HCG earlier in a pregnancy than urine or home pregnancy tests can. These tests can confirm a pregnancy about 8 to 10 days after ovulation. Blood pregnancy tests will yield a positive result if they detect 5 miu or more of HCG in the blood. ...Read more

If i ovulate on sept 2, when is the SOONEST i can do pregnancy blood test? Thank you for the answer
Patience...: Patience is a virtue that all parents and future parents should seek. A urine pregnancy test done correctly should give a reliable result 3 weeks after sex. A blood test is not needed. Hopefully, it will be what you wish it to be, but there should be no need to give it another thought until then. If one's normal regular menstrual period comes, she is not pregnant and a test is not needed. ...Read more
I took a pregnancy blood test at 9 DPO and it was negative, is there a chance I could still be pregnant?
Maybe: It could have been too soon. Take it again when you have missed period for 2 days, if the test says it is accurate by then. Follow the instructions exactly! If negative, repeat in a week. If still negative & no period, consider seeing doc for blood pg test. Also, assume you're pregnant until sure you're not & no drugs, alcohol, tobacco, any otc meds or drugs not okayed by doc, Prenatal vit.s OK. ...Read more
If someone ovulates and concieves and then a week later takes a pregnancy blood test, how accurate will that be?
Not if it's negative: A positive test is pretty accurate, but a negative test is not reliable that early. It can take 11 days after conception to show a positive blood test result. To make it more complicated, since sperm can live for up to 5 days inside a woman, and ovulation is sometimes difficult to pinpoint exactly, she can conceive later than she thought, and need to wait longer for a positive result. ...Read more
Hi I went for a pregnancy blood test but it came back negative and I have been taken early first response test and all 6 came back with lightpinkfaint?
Yes: Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. ...Read moreSee 1 more doctor answer
No such thing: You can not be weakly positive, or a little pregnant. It is either positive or negative. Odds are, it is positive. If you are not sure how to read the test, wait a day or two and repeat it with a test that has 1 line or 2 or turns a definitive color, etc. So you have no question as to the answer. Good luck. ...Read more
You can: But the utility of a pregnancy test in this setting is more so to assess for the possibility of a spontaneous abortion. Remember, spotting during pregnancy, especially the first trimester is rather common. I would say though, if you urine pregnancy testing is negative, the odds that this is pregnancy related bleeding goes way down. ...Read more
