A pregnancy test is a way to determine if youre pregnant by looking at the amount of human chorionic gonadotropin in your body.

Pregnancy Blood Test Results
Did your test come back positive for hCG in your blood? Then congratulations are in order youre definitely pregnant!
A test that comes back negative for hCG usually means a woman isnt pregnant. But rarely, its possible for an hCG blood test to deliver a false negative.
If your test doesnt detect any hCG but you and your provider still suspect youre pregnant, he or she may recommend re-doing the test in a week. At that point, if youre pregnant, your blood hCG levels should be higher and more easily detected.
If you were given a quantitative hCG test, the results will tell you exactly how much hCG is in your bloodstream. Try not to read into these numbers too closely or compare them with other moms-to-be. Theres a very wide range for what counts as normal and no two pregnant womens levels are exactly alike.
And if yours do look a little different? Take a deep breath: Everything is likely still A-okay. Most likely your due date is a little off, and in some cases, higher levels could mean youre having twins.
Ultimately, the most important thing is that your pregnancy is progressing normally and that your hCG levels continue going up until weeks 7 to 12 of pregnancy .
But if you have any questions or concerns, bring them up with your practitioner. Chances are he or she will be perfectly happy with your numbers and you should be too.

The presence of the hormone in urine is a strong indication of pregnancy.
Urine hCG qualitative tests do not show the specific hormone level, so it cannot be used to determine the proper development of a pregnancy. The test can also result in false negatives and false positives. However, some urine tests are highly sensitive and can detect lower hCG levels, resulting in early pregnancy detection.

Which Ultrasound Imaging Techniques Are Available
There are several types of ultrasound imaging techniques. As the most common type, the 2-D ultrasound provides a flat picture of one aspect of the baby.
If more information is needed, a 3-D ultrasound exam can be done. This technique, which provides a 3-D picture, requires a special machine and special training. The 3-D image allows the health care provider to see the width, height and depth of the images, which can be helpful during the diagnosis. The 3-D images can also be captured and saved for later review.
The latest technology is 4-D ultrasound, which allows the health care provider to visualize the unborn baby moving in real time. With 4-D imaging, a three-dimensional image is continuously updated, providing a live action view. These images often have a golden color, which helps show shadows and highlights.

At-home pregnancy tests are a fast and convenient way to take a pregnancy test. Home pregnancy testing is very similar to qualitative urine hCG testing performed in the laboratory, but there are some important differences to be aware of:

- At-home pregnancy tests should typically be done using a urine sample taken the first time you urinate in the morning. This is when urine is the most concentrated and has enough hCG to be detected.
When used correctly, most at-home pregnancy tests produce the same result as the qualitative urine hCG test done by a medical provider.
