blood pregnancy test

A positive blood pregnancy test result is a pregnancy hCG test that is positive about 3-4 days after implantation. In most cases, a blood pregnancy test is run by the obstetrician during the first office visit. While the urine pregnancy test can detect the presence of the hCG hormone, it cannot tell the doctor how much of the hormone is present in the body. The blood pregnancy test delivers an hCG level which can tell a lot about the baby, or babies.

How early after conception and implantation can a pregnancy be detected with a positive pregnancy test?

If you are pregnant, then the urine home pregnancy test HPT can be positive as early as 10-11 days after ovulation and fertilization. That would be several days before the next menstrual period. The blood pregnancy hCG test is usually positive several days earlier. 


Q: What are the reasons for a false positive or false negative pregnancy test result?

A: A pregnancy hcg test checks for the presence of the pregnancy hormone hCG or human chorionic gonadotropin in your body. A false positive hCG pregnancy test, a positive hCG test when you are not pregnant, rarely happens, but if it happens then it can be seen both with blood and urine tests, though in each case, the causes can be slightly different. 


hCG pregnancy hormone information on hCG numbers in early pregnancy and all the facts are presented here. Urine tests measure the urine HCG numbers in early pregnancy qualitatively, which means that the HPT results are either "positive" or "negative" while blood HCG numbers in pregnancy give a specific number in mIU/ml. 


When is the hCG titer in the blood considered to be too low and when is it considered to be slow rising?

A lot of science goes in to getting pregnant, and even more goes into the pregnancy itself.  Biology, physics (if you don't know what I mean about that, you haven't felt the inverse pressure of your growing belly on your lower back!), and mathematics too--you know, baby + bladder = higher water bill?  

And that's just the science on the inside.  The science on the outside is enough to make your newly-hormonal brain flip inside-out.  


There are two types of pregnancy test – blood and urine – that most women come in contact with when trying to conceive. The urine pregnancy test can be administered at home or in the doctor’s office (they are both generally the same test), but the blood pregnancy test is reserved for the lab. Both tests are looking for the same hormone, human chorionic gonadotropin, but they are testing for different things. Is the blood test worth the extra time and money?


A woman;s  body is constantly changing. Hormone levels rise and fall as do blood glucose and blood pressure. Many of the early signs of pregnancy are also signs of other physical changes in the body.


HCG is the abbreviation for "Human Chorionic Gonadotropin".  HCG is the "pregnancy hormone" which is being produced by the placenta as soon as implantation happens about one week after fertilization and ovulation. hCG then continues to rise until about 10-12 weeks at which point it will stabilize or drop.

Many women wonder whether they have a normal hCG level or not.


A urine home pregnancy test HPT usually becomes positive within a week or so after implantation, or around the time of your expected menstrual period. It becomes positive about 12-14 days days after ovulation and fertilization.
