Often, ladies notice evaporation lines after a pregnancy test at home. Evap lines can create a feeling of anxiety. The question is, how common are evaporation lines? Why do they appear?
Evaporation line on the pregnancy test kit, what does it mean?
The sight of two lines on a pregnancy test kit can be a source of anxiety for many women. These two lines usually consist of a dark line and another hardly visible colorless line. The colorless line is what we refer to as the evaporation line. During a pregnancy test, one of the mistakes you don’t want to make is wrongly interpreting your result. Before proceeding with the question, “how common are evaporation lines?” it is vital to ensure you read the manual before taking action.
When faint lines appear within the reaction time of 5 minutes, this can be an indication of pregnancy. Nonetheless, evaporation lines must not be mistaken for pregnancy. Evap lines are not an indicator of pregnancy; they are simply signs of urine evaporation.
How does the evaporation line on a pregnancy test happen?
Giving the best answer to the question “how common are evaporation lines?” depends largely on certain factors. One of these factors includes timing. When a woman waits for too long after the reaction period, evaporation lines may appear. Typically, evaporation lines appear simply because the test strip is wet.
Nonetheless, not every individual will get the opportunity to see an evaporation line. Urine composition varies for different people. For some women, an evaporation line may appear a little after 5 minutes. Others may have to wait for over an hour or more.
Ways to avoid an evaporation line during a pregnancy test
- Reading the instructions by the manufacturer is important if you want to avoid evaporation lines. If you follow the right instruction, you may not need to ask the question of how common are evaporation lines. An evaporation line is what we refer to as a false positive. It is one of the errors that can occur from a pregnancy test. There are also true false positives and false negatives that rarely or may never occur.
- Get a watch to ensure proper timing. Most test strip indications recommend you read within 5 to 30 minutes.
- Use a digital test kit to get rid of all the misreading that may occur as a result of evaporation lines. Using a digital will also save you from mixing up yesterday’s experiment with the current.
Evaporation lines misunderstanding
Some people often misunderstand the evaporation line as a faint line. A faint line that appears within the reaction period is an indication of pregnancy. A faint line can occur when the level of the hCG is low (diluted urine). A faint line can also occur when you test too early. Another thing that can lead to a faint line is a chemical pregnancy. In this case, the hCG is not enough to cause a reaction.
It is, therefore, important to take note of the difference. A faint line within the reaction period is an indication of pregnancy. Any line that appears after the reaction period is over is an evaporation line.
Home pregnancy test strips—types and mode of use
Home urine pregnancy tests are reliable today and can produce an accurate result. Two types of pregnancy test kits are popular or home use. These two are the urine dipsticks/test strip and the urine test device. You can either dip the test strip inside a cup of urine or splashing urine on the test strip. In a positive pregnancy test, the dye will accumulate on the antibody area of the strip to produce a second line. If there is no hCG present in the urine, there will be nothing to react with, and no second line will appear on the strip.
The urine test device requires dipping the device into a cup of urine. Modern versions of these devices have a small cup on one end that collects a small quantity of urine. On the center of the device is a result window where you see the results of your test. The up and the result window make up the test area. Using an eyedropper tool, add drops of urine into the cup. In the case of a positive result, the color of the test device will change. Every test strips whether digital of manual has a control line. The control line indicates that the test strip is working fine.
How common are evaporation lines?
You may never get to see an evaporation line if you use your test strip properly all the time. However, some people fail to read and follow the directive by the manufacturer. To them, evaporation lines can be very common.
