Will too much urine on the pregnancy test stick cause errors? Will too much urine on the pregnancy test stick affect the results?

When using a pregnancy test stick, as long as the urine does not exceed the detection line and does not spill onto the display area, a little more or less will not have much impact. However, if it exceeds the detection line, it may have a certain impact on the result.

Within the urine range specified in the instructions, a little more will actually make the verification result more accurate.

The most accurate sample for measurement is the first urine discharged in the morning. If you are really pregnant, the HCG content in the morning urine is the highest, so the result is the most reliable. Urine should be collected in a clean and dry container to avoid affecting the measurement results.

The urine volume should not exceed the max line. If the urine does not reach the display area, it will not affect the result.

Some pregnancy test sticks are used in a way that the tester aims at the urine suction hole and urinates directly on it. Therefore, sometimes the urine volume is not well controlled and may lead to too much urine. In this case, the result will not be affected, because the pregnancy test stick uses the reaction presented by the combination of single and multiple HCG antibodies in the device and antigens in the urine to determine whether the pregnancy is present. As long as there is a certain amount of urine, it can be tested even if you urinate too much or directly insert the urine suction hole into the urine cup. Just avoid letting the urine reach the display area.

1. Direct urine spray

If the instructions for using the urine test on the pregnancy test stick require the tester to urinate directly into the urine absorption hole, then the urine only needs to be poured into the urine absorption area and avoid the display area to be considered valid.

2. Urine dripping

If the instructions for using the urine pregnancy test stick require the tester to use a plastic straw to suck up the urine and drop it into the small hole in the sample area, then about 3 drops of urine need to drip into the urine suction hole to be considered valid.

3. Insert urine cup

If the instructions for using the urine pregnancy test stick require the tester to collect the urine in a small cup and then insert the sample area at one end of the test paper into the cup, then make sure that the sample area contacts the urine and does not exceed the max line, then it is considered valid.

Usually, it is most accurate to use a pregnancy test stick when your period is 7 to 10 days late.

Because pregnancy test sticks mainly determine whether a woman is pregnant by detecting the HCG content in the urine of women of childbearing age, and since the amount of HCG emitted by different women varies, using pregnancy test sticks for testing too early is likely to result in inaccurate test results. The concentration of HCG in women's urine is highest when the menstruation is delayed by 7 to 10 days, so the test results obtained are often the most accurate.
