To confirm pregnancy, one of the tools used most often are urine pregnancy tests and blood tests. Upon choosing it, many mothers tend to buy several brands to be sure. The truth is that all urine pregnancy tests without exception detect a hormone that is released at the time of pregnancy.
What hormone is released?
Pregnancy tests, both urine and blood, detect human chorionic gonadotropin hormone (hCG), which is secreted during pregnancy.
When can occur a false positive?
In some cases, a pregnancy test may give a wrong result, which is attributed to several specific conditions of the patient.
In the case of false positives, often due to:
• If the patient has a tumor on the ovary, which which may result is an increase in the production of hCG
• If the patient has protein in the urine
• If the patient is under treatment for fertility
• If you have had a recent birth
• If you have recently suffered a spontaneous abortion
• If urine was collected incorrectly, ie directly from the toilet
• If the pregnancy test has been affected by some external factor, such as temperature
What are urine pregnancy tests?
Pregnancy tests sold at the pharmacy are for the mother to know whether or not pregnant. These tests identify the hormone hCG pregnancy test. However, such tests must be performed with a certain time after possible conception, since a higher level of hCG to be detected, otherwise the blood tests necessary.
Using a pregnancy test?
For a pregnancy test, consider the following:
• Be sure to read the test. Each brand has its particularity, so it is best to take the time to read the instructions and avoid altering the outcome
• Perform the test with the first morning urine. This will help guarantee that the levels of hCG in urine are the highest of the day
• Avoid drinking too much before the test, as this will only cause the urine is diluted and more difficult to identify the hormone. Ideally, as does drinking fluids regularly and wait until you feel like going to the bathroom
• If you are taking any medications, consult your doctor to see if it can affect the test or not

The blood test can be performed in 10 to 14 days after ovulation. To do this, go to a lab and ask them to perform a pregnancy test. Through a blood sample, you can tell if you are pregnant or not.
Blood tests to confirm pregnancy have a 90% accuracy, so they are very reliable.
