A serum pregnancy test is a blood test performed in a physician's office or laboratory to get quantitative hCG. A "triple screen" is a blood test for hCG, AFP, and uE3.
The other type of pregnancy test is an over-the-counter test which examines urine for the presence of hCG.

How it is possible for some one to test negative on a simple urine test and positive on the standard test?
Pregnancy tests measure the level of hcg in your body. When you are pregnant, and as your pregnancy progresses, your hcg level rises. When you take a urine pregnancy test and it comes back negative, the level of hcg is not high enough to register on the test. When the quantitative serum pregnancy test is positive, it is a more acurate reading of how far along in your pregnancy you actually are.

Can you determine pregnancy from a blood test?
A pregnancy blood test or a pregnancy serum test is a test that measures the exact amount of the pregnancy hormone, human chorionic gonadotropin (hCG), in the bloodstream of a woman to detect pregnancy. Human chorionic gonadotropin (hCG) is a hormone that is produced by the placenta of a pregnant woman. It is detectable in the blood and urine within 10 days of fertilization. There are two types of blood pregnancy tests, namely, quantitative blood test which measures the exact amount of hCG in the blood and qualitative hCG blood test which gives a simple yes or no answer to whether you are pregnant or not.
Can you be pregnant if your hometest came back negative and you had IVF?
Commonly a serum pregnancy test is checked 14 days after egg retrieval in an IVF cycle. Sometimes if a patient performs a home pregnancy test at that time instead, it could read false negative even though she may actually be pregnant. This is because the home test cannot detect low levels of the HCG hormone, however a serum test can. For this reason most IVF centers advise against taking a home test
