How to Use a Pregnancy Test: General Guidelines
Inside every home pregnancy test kit is an instructional guide that teaches how to use a pregnancy test. Before performing the urine test, make sure to check the expiration date on the packaging. This is an important factor for the test to work correctly.
There are many different home pregnancy tests available in the market, but they all generally follow the same guidelines and principles:
- Remove the plastic lid in order to reveal the absorbent window where you are supposed to place the urine sample.
- Align the absorbent tip directly where the urine stream is supposed to land. Collect the urine sample in about 7-10 seconds of flow to ensure that the testing tool obtains a sufficient amount. You may also consider another method of collecting the sample by placing the urine in a clean container. Afterward, go straight to dipping half of the absorbent pad in the urine for at least 10 seconds. It is also best to collect early morning urine, as it is more concentrated.
- Once the device is able to gather the necessary sample, you may re-cap it and leave it horizontally on a clean surface.
- Wait for the test to finish processing for 5 minutes.
How to Use a Pregnancy Test.: Interpretation of the Results
Pregnancy tests can determine the level of human chorionic gonadotropin (hCG) in the urine sample. The hCG levels provide an indication of either a positive or a negative result based on the number of lines that appear.
Two Lines = Positive (Pregnant)
Both the Control (C) and Test (T) sections have distinct and consistent color bands. The bands’ color intensity varies depending on the concentration and stage of hCG levels. The two lines yielded indicate a high hCG level (above 25 mIU/mL).
One Line = Negative (Not Pregnant)
On the top Control (C) section, there is only one color band, which indicates a low level of hCG (less than 5 mIU/mL).
