Quantitative hCG Blood Testing - this form of test not only looks for the presence of hCG but the hCG levels present, giving an indication not only of pregnancy but can also give an indication of how far along the pregnancy has progressed.

Blood tests are generally considered to be more accurate than urine tests.

Qualitative hCG Blood Testing - much like urine testing this type of blood test only looks for the presence of hCG in the blood, giving a yes or no result.

There are two kinds of blood pregnancy tests that can be performed: Blood pregnancy tests are performed by a doctor who will take a blood sample and send it to a lab for testing. Blood tests can detect the presence of hCG by around 11-14 days of suspected pregnancy. Many home pregnancy test kits recommend testing the first urine of the morning as it is more concentrated and can give a better indication of the presence of pregnancy hormones.Īlthough blood tests also look for the presence of hCG to determine pregnancy, blood pregnancy tests are generally more accurate and can be used earlier. No matter the specific method required, urine testing is generally very fast and can show a result in only a few minutes.Home testing kits are readily available at chemist shops as well as a number of supermarket chains. These tests utilise a strip of material with a plasma membrane housing antibodies that can bind to hCG and dyes that react to this binding to give a visual indication of the presence of the hormone.īoth at home testing kits and urine tests that a doctor may use work in this fashion but the method of testing can vary from manufacturer to manufacturer, with some tests needing to be dipped into a container of urine and others that can be held in the flow of urine. Urine pregnancy tests are qualitative, meaning that they only test for the presence or absence of hCG, giving a yes or no result. There are two major types of pregnancy tests performed: urine and blood. After 10-12 weeks of pregnancy the levels of hCG plateau and then begin to fall.

Human Chorionic Gonadotropin (hCG) starts being produced when an egg is implanted in the uterus and the levels of the hormone increase exponentially for the first seven to 10 weeks of pregnancy, making this the optimal window for testing. Both home testing kits and tests performed by a doctor look for this hormone, with the major difference being that home test kits only test urine, but doctors may opt for a far more accurate and detailed blood test to not only detect pregnancy but how far along the pregnancy may be. Modern tests examine the blood or urine of a woman to determine pregnancy by detecting the presence of a substance known as Human Chorionic Gonadotropin (hCG), a hormone produced by the placenta. No matter the form the testing took, these tests invariably looked for the same thing - evidence of hormones made during pregnancy. Pregnancy testing has changed markedly over the years, from injecting small animals with a woman’s urine to see if the hormones in the urine would cause the animal to ovulate or produce sperm, to urine testing that didn’t involve any animal involvement. Home pregnancy tests are 100% safe, so when in doubt, test.Some medical conditions and medications can also affect the accuracy of urine based testing.If used improperly or too early, home pregnancy tests can offer false positive or false negative results.Doctors may perform a blood test to determine both the presence and amount of hCG giving an indication of how far along the pregnancy has progressed.

Home test kits test for the presence of hCG in urine.Modern pregnancy tests work by detecting the presence of a hormone produced by the placenta known as hCG.
