There are different types of urine tests, which can be performed at home or at a doctor's office. A common pregnancy urine test is the urine dipstick test where urine is collected in a cup and a special urine dipstick is placed into the urine.
Another type of test involves placing a stick into the path of the urine stream and catching the urine midstream. It is important to understand that at different parts of the urine stream (beginning, middle, and end) the urine can be quite different in substance.
Usually the urine dipstick or other instruments to help with the test turn a different color to specify the presence of various chemicals. For accurate results, it is important to follow the test instructions carefully. It is very common for human error in test interpretation to cause unnecessary worry or concern in patients.
For women who are taking the urine test to see whether they are pregnant, it is usually best to perform the test on the first day of your missed period. The first missed period is typically a few weeks after conception.
The urine tests tend to have over 97% accuracy when performed as the instructions suggest. More error is added due to possible misunderstanding of the test or confusion with the results. Taking the urine test can be a stressful event and human error is quite common. If you are uncertain of the accuracy of the results, or your own ability to perform the test, you may want to consult with a medical professional.
Common pregnancy symptoms are missed periods, nausea, breast tenderness and fatigue. If you continue to experience these symptoms, you may want to take or re-take the test, or consult with a medical professional if the results of the home tests show up as negative.
